/**
 * A {@code BuildLauncher} allows you to configure and execute a Gradle build.
 * 

* Instances of {@code BuildLauncher} are not thread-safe. You use a {@code BuildLauncher} as follows: * *

    *
  • Create an instance of {@code BuildLauncher} by calling {@link org.gradle.tooling.ProjectConnection#newBuild()}. *
  • Configure the launcher as appropriate. *
  • Call either {@link #run()} or {@link #run(ResultHandler)} to execute the build. *
  • Optionally, you can reuse the launcher to launch additional builds. *
* * Example: *
 * 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();
 * }
