    Launch configuration

    -

    Here is how to configure your development environment.

    +

    Configuring IDEA

    +

    + Working on the Kobalt code base with Intellij IDEA is very easy. +

    +

    Edit kobalt.version

    +

    + First of all, edit the file src/main/resources/kobalt.properties and set it + to a nonexistent version. For example, if the current version is 0.399, + set it to 0.400. +

    +
    +                    kobalt.version=0.400
    +                
    +

    + When you launch Kobalt from IDEA with a nonexistent version, Kobalt will show a message saying + that it couldn't locate that version and instead, it will use the classes generated by IDEA. This + way, you will always be running the files that you just modified with IDEA. On start up, + Kobalt will display a message looking like: +

    +
    +Couldn't find .../kobalt-0.400.jar, using ...
    +                
    +

    + Note that at the moment, Kobalt expects to be located in $HOME/kotlin/kobalt. +

    +

    Launch configuration

    +

    Next, create a launch configuration in IDEA.

    Kobalt's main class is com.beust.kobalt.MainKt. Here is a typical launch configuration:

    Build file classpath

    +

    + If you are writing code or an inline task in your build file that requires additional libraries, + you can specify these dependencies with the buildFileClasspath() directive, which accepts a list + of dependencies in parameters.

    +

    Dependency versions

    +

    + Kobalt lets you specify Maven coordinates in one line, such as "org.testng:testng:6.9.10". Note that Kobalt uses the Maven Coordinates defined in the Maven specification, which are a little bit different from the ones that Gradle uses. +

    +

    + The standard format for such coordinates, as explained in the link above, is: +

    +
    +groupId:artifactId:packaging:classifier:version
    +

    + packaging (e.g. "jar") and classifier (usually an arbitrary name) are optional and can be omitted. If version + is omitted, Kobalt will resolve the artifact to its latest version from all the specified repos. + Most of the time, you will only specify groupId, artifactId and version, but if you ever need to specify additional components such as packaging (sometimes referred to as "extension") or classifier, + please take note that these should appear before the version number. +

    +

    + Here are a few examples of valid Maven coordinates: +

    +
    +# No version, resolves to the latest

    Settings

    +

    + You can define settings that will apply to all your Kobalt builds by creating + the file ~/.config/kobalt/settings.xml: +

    + +
    +<kobalt-settings>
    +    <local-repo>/Users/beust/my-kobalt-repo</local-repo>

    +

    + Here is a list of the parameters you can configure: +

    + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + +
    NameDefaultDescription
    default-reposDefault reposList of repos overriding the default ones that Kobalt uses.

    local-repo~/.kobalt/repositoryWhere Kobalt stores all the downloaded dependencies.
    + +

    Templates

    +

    + Templates are invoked with the --init parameter and typically used when you are creating + a new project and you want Kobalt to generate a few files to get you started. Plug-ins can provide multiple + templates and you can invoke as many as you need to get your project started. You can get a list of available + templates with the --listTemplates parameter: +

    +
    +$ kobaltw --listTemplates
    +Available templates
    +  Plug-in: Kobalt
    +    "java"              Generate a simple Java project
    +    "kotlin"            Generate a simple Kotlin project
    +    "kobaltPlugin"      Generate a sample Kobalt plug-in project
    +

    + You can then invoke any of these templates with --init: +

    +$ kobaltw --init kobaltPlugin
    +Build this project with `./kobaltw assemble`
    +

    + Kobalt just generated a full project that will create a simple Kobalt plug-in. This plug-in adds + a simple task to Kobalt, so let's build it and test it: +

    +
    +$ ./kobaltw assemble
    +----- kobalt-line-count:compile
    +----- kobalt-line-count:assemble
    +Created .\kobaltBuild\libs\kobalt-line-count-0.18.jar
    +Created .\kobaltBuild\libs\kobalt-line-count-0.18-sources.jar
    +Created .\kobaltBuild\libs\kobalt-line-count-0.18-javadoc.jar
    +Wrote .\kobaltBuild\libs\kobalt-line-count-0.18.pom
    +BUILD SUCCESSFUL (5 seconds)
    +

    + We can test this plug-in with another useful command line parameter: --pluginJarFiles. You give this parameter a comma-separated list of jar files, each of which is expected to be a Kobalt plug-in. Let's invoke + Kobalt with it and ask for a list of available tasks (some of the output was elided): +

    +
    +$ ./kobaltw --pluginJarFiles kobaltBuild/libs/kobalt-line-count-0.18.jar --tasks
    +...
    +  ===== kobalt-line-count =====
    +    dynamicTask         Dynamic task
    +    lineCount           Count the lines
    +...
    +

    - You can create settings that will apply to all your Kobalt builds by creating - a file in ~/kobalt/settings.xml: + Kobalt loaded this plug-in and added the tasks that it provides. The parameter + --pluginJarFiles is mostly targeted at Kobalt plug-in developers so you can test + your plug-ins on your local file system without having to upload them to a Maven repo. More commonly, + you will run templates from plug-ins published in a Maven repository, and for this, + you use the --plugins parameter. For example, let's see what templates the + Android Kobalt plug-in offers:

    -<kobalt-settings>
    -    <localRepo>/Users/beust/my-kobalt-repo</localRepo>
    -</kobalt-settings>
    -          
    -

    - Here is a list of the parameters you can configure: -

    - - - - - - - - - - - - - - - - - - -

    +

    +We see the same plug-ins we just reviewed and a new one provided by the Android plug-in called +"androidJava". The --plugins parameter expects a comma-separated list of plug-in +id's and it acts as if you had specified these Maven id's in your Build.kt file. +The reason why this parameter is useful is that typically, when you run a template, you don't +have a build file yet since you are starting a project from scratch. +

    +

    Testing

    +
    +dependenciesTest {
    +    compile("org.testng:testng:6.9.9")
    +}
    +

    + By default, Kobalt supports TestNG, JUnit and Spek. You can also configure how your tests run + with the test{} directive: +

    +
    +test {
    +    args("-excludegroups", "broken", "src/test/resources/testng.xml")
    +}
    +

    + The full list of configuration parameters can be found in the TestConfig class. +

    +

    + Additionally, you can define multiple test configurations, each with a different name. Each + configuration will create an additional task named "test" followed by the name of + that configuration. For example: +

    +
    +test {

    +

    Setting up IDEA

    +

    Launch configuration

    +

    + The simplest way to run your plug-in in your IDE is to create a main function in the main class of your + plug-in as follows: +

    +
    +fun main(argv: Array<String>) {
    +    com.beust.kobalt.main(argv)
    +}
    +
    +

    + In order for this code to compile, you will have to switch the dependency of your plug-in from + kobalt-plugin-api to just kobalt, which is the actual application (and which + therefore contains the main() entry point). +

    +
    +        // Normal dependency
    +        compile("com.beust:kobalt-plugin-api:$KOBALT_VERSION")
     
    -                

    Plug-in architecture

    -

    -

    - Plug-ins often produce files and data that other plug-ins need to use in order for a build to succeed. For example, - the Android plug-in needs to generate a file called R.java and then make this file available at - compile time by the Java or Kotlin (or any other language) plug-in. Since plug-ins have no idea about what other - plug-ins are currently enabled and running, they can't directly talk to each other so instead of calling into - Kobalt, Kobalt calls into them. This is done by declaring various "actors" that Kobalt will invoke whenever - it needs the information that your plug-in produced. This is a design pattern often referred to as the - "Hollywood Principle": "Don't call us, we'll call you". -

    -

    - These "actors" are exactly what the kobalt-plugin.xml file describes. This file informs Kobalt about - the various ways in which your plug-in participates in the build system by specifying 1) plug-ins, 2) contributors - or 3) interceptors. -

    -

    + // Development dependency + compile("com.beust:kobalt:$KOBALT_VERSION") +
    +

    + You might find it convenient to leverage Kobalt's ability to use regular Kotlin variables to make things easier: +

    +
    +val dev = false
    +val kobaltDependency = if (dev) "kobalt" else "kobalt-plugin-api"

    kobalt-plugin.xml

    -

    - The kobalt-plugin.xml file (stored in META-INF in the jar file of your plug-in) is mandatory and describes all the actors of your plug-in. This file contains a list of class names, each of which is expected to implement at least one of IPluginActor's interfaces: -

    +val p = project { + // ... + + compile("com.beust:$kobaltDependency:$KOBALT_VERSION") +} +
    +

    + Then you can simply set the dev to true during development and back to false + when you are ready to publish your plug-in. + +

    +

    + Then resync your build file in IDEA and your main() function should now build and be launchable. + You can right click on that class file and select "Debug <your class name>", which will launch Kobalt + with your plug-in. You can set a breakpoint in one of your tasks or anywhere that gets invoked. Don't forget + to invoke this launch configuration with the regular parameters passed to Kobalt (e.g. "assemble"). +

    +

    Local dependencies

    +

    + In the process of building your plug-in, you will probably be invoking it from test projects and since + you will be making changes to your plug-in and generating jar files often, you might find it more convenient + to have these test projects point to your local jar file instead of the Maven one (which would require you + to upload your plug-in all the time). For this, you might find the file() and homeDir + () directives convenient: +

    +
    +    // Regular dependency
    +    compile("com.example:myPlugin:0.1")
    +
    +    // Development dependency
    +    compile(file(homeDir("kotlin/myPlugin/kobaltBuild/libs/myPlugin-0.1.jar"))
    +
    +

    + With this latter configuration, simply build your plug-in to generate the jar file with ./kobaltw + assemble, switch to your test project and invoke Kobalt on it so that your plug-in will get invoked + and you should see the latest version of your code being invoked. +

    +

    +Tasks are provided by plug-ins and can be invoked from the command line, e.g. ./kobaltw assemble. There are two kinds of tasks: static and dynamic. +

    +

    Static tasks

    +

    +Static tasks are functions declared directly in your plug-in class and annotated with the @Task annotation. Here is an example: +

    -@Task(name = "lineCount", description = "Count the lines", runBefore = arrayOf("compile"))
    +@Task(name = "lineCount", description = "Count the lines", dependsOn = arrayOf("compile"))
     fun lineCount(project: Project): TaskResult {
         // ...
         return TaskResult()
     }
     
    -

    - A Kobalt task needs to accept a Project in parameter and return a TaskResult, which indicates whether this task completed successfully. -

    -

    - The @Task annotation accepts the following attributes: -

    -
    name
    -
    The name of the task, which will be used to invoke it from the command line.
    -
    description
    -
    The description of this command, which will be displayed if the user invokes the usage for the kobaltw command.
    -
    runBefore
    -
    A list of all the tasks that this task should run prior to.
    -
    runAfter
    -
    A list of all the tasks that should run before this task does.
    -
    alwaysRunAfter
    -
    A list of all the tasks that will always be run after this task if it's invoked.
    -
    -

    -

    - The difference between runAfter and alwaysRunAfter is subtle but important. runAfter - is just a declaration of dependency. It's basically the reverse of runBefore but it's useful in case - you are not the author of the task you want to run before (if you were, you would just use the runBefore - annotation on it). Since you can't say "a runBefore b" because you don't own task "a", - you say "b runAfter a". -

    -

    - For example, compileTest is declared as a runAfter for the task compile. - This means that it doesn't make sense to run compileTest unless compile has run first. - However, if a user invokes the task compile, they probably don't want to invoke compileTest, - so a dependency is exactly what we need here: invoking compileTest will trigger compile - but not the other way around. -

    -

    - However, there are times where you want to define a task that will always run after a given task. - For example, you could have a signJarFile task that should always be invoked if someone builds a jar - file. You don't expect users to invoke that target explicitly, but whenever they invoke the assemble - target, you want your signJarFile target to be invoked.

    Dynamic tasks

    +

    +A Kobalt task needs to accept a Project in parameter and return a TaskResult, which indicates whether this task completed successfully. +

    +

    +The @Task annotation accepts the following attributes: +

    +
    name
    +
    The name of the task, which will be used to invoke it from the command line.
    +
    description
    +
    The description of this command, which will be displayed if the user invokes the usage for the kobaltw command.
    +
    dependsOn
    +
    A list of all the tasks that this task depends on.
    +
    reverseDependsOn
    +
    Make the following tasks depend on this task.
    +
    runBefore
    +
    A list of all the tasks that this task should run prior to.
    +
    runAfter
    +
    A list of all the tasks that should run before this task does.
    +
    +

    +

    + Kobalt defines two different concepts for tasks: dependencies and orderings. And for each of this concept, + you can define the relation to go in one direction or the other. +

    +

    + If your task cannot run until another task has run, you need to declare a dependency. Dependencies cause + additional tasks than those requested to be executed. For example, "assemble" depends on "compile", which means that whenever you invoke "assemble", "compile" + will be automatically run first. This is a dependency and it is controlled by "dependsOn" and + "reverseDependsOn". You can see "reverseDependsOn" as a way to insert your task before an existing task. +

    +

    + Orderings, controlled by "runBefore" and "runAfter" merely specify an ordering + but do not pull new tasks in. This is how you tell Kobalt "In case the user asks for my task to run, + here is when it should be invoked", but your task will run only if it's explicitly invoked by the user. +

    +

    +Here are a few different scenarios to illustrate how the three attributes work for the task example: +

    +Result of the command ./kobaltw --dryRun compile +

    +
    + Make the "example" task depend on "compile". +
    reverseDependsOn = "compile" +
    clean
    +example
    +compile
    +
    + Insert the "example" task before "compile". +
    runAfter = "compile" +
    clean
    +compile
    +
    + Make "example" run after "compile" but only if it's invoked explicitly. +
