+## Version is "unspecified"
+
+This is a common problem steaming from the configuration and build phases in Gradle.
+
+It is always preferable to access to version during the execution stage, in a `doFirst` or `doLast` closure within your tasks:
+
+```gradle
+task foo() {
+    doFirst {
+        println project.version
+    }
+}
+```
+
+or if absolutely necessary, at the end of the configuration stage in a `project.afterEvaluate` block:

+```gradle
+foo {
+    project.afterEvaluate {
+        println project.version
+    }
+}
+```
