# ModelBuilder

interface ModelBuilder<T> : ConfigurableLauncher<T> (source)

A `ModelBuilder` allows you to fetch a snapshot of some model for a project or a build. Instances of `ModelBuilder` are not thread-safe.

You use a `ModelBuilder` as follows:

- Create an instance of `ModelBuilder` by calling model.
- Configure the builder as appropriate.
- Call either get or get to build the model.
- Optionally, you can reuse the builder to build the model multiple times.

Example:

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

    try {
       ModelBuilder<GradleProject> builder = connection.model(GradleProject.class);

       //configure the standard input in case your build is interactive:
       builder.setStandardInput(new ByteArrayInputStream("consume this!".getBytes()));

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

       //get the model:
       GradleProject project = builder.get();

       //query the model for information:
       System.out.println("Available tasks: " + project.getTasks());
    } finally {
       connection.close();
    }
