LongRunningOperation

public interface BuildLauncher
extends LongRunningOperation

A BuildLauncher allows you to configure and execute a Gradle build.

Instances of BuildLauncher are not thread-safe. You use a BuildLauncher as follows:

• Create an instance of BuildLauncher by calling ProjectConnection.newBuild.
• Configure the launcher as appropriate.
• Call either run() or run(ResultHandler) to execute the build.
• Optionally, you can reuse the launcher to launch additional builds.

 ProjectConnection connection = GradleConnector.newConnector()
    .forProjectDirectory(new File("someFolder"))
    .connect();

 try {
    BuildLauncher build = connection.newBuild();

    //select tasks to run:
    build.forTasks("clean", "test");

    //include some build arguments:
    build.withArguments("--no-search-upward", "-i", "--project-dir", "someProjectDir");

    //configure the standard input:
    build.setStandardInput(new ByteArrayInputStream("consume this!".getBytes()));

    //in case you want the build to use java different than default:
    build.setJavaHome(new File("/path/to/java"));

    //if your build needs crazy amounts of memory:
    build.setJvmArguments("-Xmx2048m", "-XX:MaxPermSize=512m");

    //if you want to listen to the progress events:
    ProgressListener listener = null; // use your implementation
    build.addProgressListener(listener);

    //kick the build off:
    build.run();
 } finally {
    connection.close();
 }

addProgressListener

public BuildLauncher addProgressListener(ProgressListener listener)

{@inheritDoc}

Since:

1.0-milestone-3

forTasks

public BuildLauncher forTasks(String... tasks)

Sets the tasks to be executed. If no tasks are specified, the project's default tasks are executed.

Parameters:

tasks - The paths of the tasks to be executed. Relative paths are evaluated relative to the project for which this launcher was created.

Returns:

this

Since:

1.0-milestone-3

forTasks

public BuildLauncher forTasks(Task... tasks)

Sets the tasks to be executed. If no tasks are specified, the project's default tasks are executed.

Note that the supplied tasks do not necessarily need to belong to the project which this launcher was created for.

Parameters:

tasks - The tasks to be executed.

Returns:

this

Since:

1.0-milestone-3

forTasks

public BuildLauncher forTasks(Iterable tasks)

Sets the tasks to be executed. If no tasks are specified, the project's default tasks are executed.

Note that the supplied tasks do not necessarily need to belong to the project which this launcher was created for.

Parameters:

tasks - The tasks to be executed.

Returns:

this

Since:

1.0-milestone-3

run

public void run()

Executes the build, blocking until it is complete.

throws:

UnsupportedVersionException When the target Gradle version does not support build execution.

throws:

UnsupportedOperationConfigurationException When the target Gradle version does not support some requested configuration option such as setStandardInput(java.io.InputStream), setJavaHome(java.io.File), setJvmArguments(String...).

throws:

UnsupportedBuildArgumentException When there is a problem with build arguments provided by withArguments(String...).

throws:

BuildException On some failure executing the Gradle build.

throws:

GradleConnectionException On some other failure using the connection.

throws:

IllegalStateException When the connection has been closed or is closing.

Since:

1.0-milestone-3

run

public void run(ResultHandler handler)

Launches the build. This method returns immediately, and the result is later passed to the given handler.

If the operation fails, the handler's ResultHandler#onFailure(GradleConnectionException)#onFailure(GradleConnectionException) method is called with the appropriate exception. See run() for a description of the various exceptions that the operation may fail with.

throws:

IllegalStateException When the connection has been closed or is closing.

Parameters:

handler - The handler to supply the result to.
