Build.gradle

Multi-Project Configuration

allprojects

The allprojects block is used to add configuration items that will apply to all sub-projects, as well as the root project.

"allprojects" is a property that contains a list with the current project and all its subprojects underneath it. It can be called with a closure, and the statements of the closure are delegated to the projects.

subprojects

The subprojects block is used to add configuration times for sub-projects only.

subprojects {
    ...
}

Respond to Build Lifecycle Events

Example of how to respond to project build lifecycle events.

allprojects {
      afterEvaluate { project ->
          if (project.hasTests) {
              println "Adding test task to $project"
              project.task('test') {
                   doLast {
                         println "running tests for $project"
                   }
              }
          }
     }
}

gradle.afterProject {project, projectState ->
      if (projectState.failure) {
          println "Evaluation of $project FAILED"
      } else {
          println "Evaluation of $project succeeded"
      }
}

Respond to Task Lifecycle Events

Examples of how to respond to task lifecycle events.

Task Creation

tasks.whenTaskAdded { task ->
      task.ext.srcDir = 'src/main/java'
}

Task Execution

gradle.taskGraph.beforeTask { Task task ->
      println "executing $task ..."
}
gradle.taskGraph.afterTask { Task task, TaskState state ->
      if (state.failure) {
          println "FAILED"
      }
      else {
          println "done"
