public interface BuildLauncher extends LongRunningOperation
BuildLauncher allows you to configure and execute a Gradle build.
Instances of BuildLauncher are not thread-safe. You use a BuildLauncher as follows:
BuildLauncher by calling ProjectConnection.newBuild().
run() or run(ResultHandler) to execute the build.
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();
}

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

BuildLauncher.
Be aware that not all of the Gradle command line options are supported!
Only the build arguments that configure the build execution are supported.
They are modelled in the Gradle API via StartParameter.
Examples of supported build arguments: '--info', '-u', '-p'.
The command line instructions that are actually separate commands (like '-?' and '-v') are not supported.
Some other instructions like '--daemon' are also not supported - the tooling API always runs with the daemon.
If an unknown or unsupported command line option is specified, UnsupportedBuildArgumentException
will be thrown at the time the operation is executed via run() or ModelBuilder.get().
For the list of all Gradle command line options please refer to the user guide
or take a look at the output of the 'gradle -?' command. Majority of arguments modeled by
StartParameter are supported.
The arguments can potentially override some other settings you have configured.
For example, the project directory or Gradle user home directory that are configured
in the GradleConnector.
Also, the task names configured by forTasks(String...) can be overridden
if you happen to specify other tasks via the build arguments.
See the example in the docs for BuildLauncher
withArguments in interface LongRunningOperationarguments - Gradle command line argumentsBuildLauncher setStandardOutput(OutputStream outputStream)
OutputStream which should receive standard output logging generated while running the operation.
The default is to discard the output.setStandardOutput in interface LongRunningOperationoutputStream - The output stream. The system default character encoding will be used to encode characters written to this stream.BuildLauncher setStandardError(OutputStream outputStream)
OutputStream which should receive standard error logging generated while running the operation.
The default is to discard the output.setStandardError in interface LongRunningOperationoutputStream - The output stream. The system default character encoding will be used to encode characters written to this stream.BuildLauncher setStandardInput(InputStream inputStream)
InputStream that will be used as standard input for this operation.
Defaults to an empty input stream.
If the target Gradle version does not support it the long running operation will fail with
UnsupportedOperationConfigurationException when the operation is started.
setStandardInput in interface LongRunningOperationinputStream - The input streamBuildLauncher setJavaHome(File javaHome)
If the target Gradle version does not support it the long running operation will fail eagerly with
UnsupportedOperationConfigurationException when the operation is started.
BuildEnvironment model contains information such as Java or Gradle environment.
If you want to get hold of this information you can ask tooling API to build this model.
If not configured or null passed the sensible default will be used.

If the target Gradle version does not support it the long running operation will fail eagerly with
UnsupportedOperationConfigurationException when the operation is started.
BuildEnvironment model contains information such as Java or Gradle environment.
If you want to get hold of this information you can ask tooling API to build this model.
If not configured, null an empty array passed then the reasonable default will be used.

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