## Kotlin Compiler Requirement
Please make sure Kotlin is installed and that the `KOTLIN_HOME` environment variable is set.
Please make sure the Kotlin compiler is [installed](https://kotlinlang.org/docs/command-line.html#install-the-compiler).
You can also manually configure the Kotlin home location as follows:
```java
@BuildCommand(summary = "Compiles the Kotlin project")
public void compile() throws Exception {
new CompileKotlinOperation()

}
```
While older version of Kotlin are likely working with the extension, only version 1.9.24 or higher are officially supported.
The Kotlin compiler executable can also be specified directly:
```java
@BuildCommand(summary = "Compiles the Kotlin project")
public void compile() throws Exception {
new CompileKotlinOperation()
.fromProject(this)
.kotlinc("/usr/bin/kotlinc")
.execute();
}
```
While older version of Kotlin are likely working with the extension, only version 1.9.24 or higher are officially
supported.
## Template Project
There is also a [Template Project](https://github.com/rife2/kotlin-bld-example) with support for the [Dokka](https://github.com/rife2/bld-dokka) and [Detekt](https://github.com/rife2/bld-detekt) extensions.
