# ProjectConnection

interface ProjectConnection : Closeable(source)

Represents a long-lived connection to a Gradle project. You obtain an instance of a `ProjectConnection` by using connect.

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

       //obtain some information from the build
       BuildEnvironment environment = connection.model(BuildEnvironment.class).get();

       //run some tasks
       connection.newBuild()
         .forTasks("tasks")
         .setStandardOutput(System.out)
         .run();

    }
