Class GradleConnector

java.lang.Object
  org.gradle.tooling.GradleConnector

public abstract class GradleConnector
extends Object

A GradleConnector is the main entry point to the Gradle tooling API. You use this API as follows:

1. Call newConnector() to create a new connector instance.
2. Configure the connector. You must call forProjectDirectory(java.io.File) to specify which project you wish to connect to. Other methods are optional.
3. Call connect() to create the connection to a project.
4. When finished with the connection, call ProjectConnection.close() to clean up.

Example:

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

 try {
    connection.newBuild().forTasks("tasks").run();
 } finally {
    connection.close();
 }
 

GradleConnector instances are not thread-safe. If you want to use a GradleConnector concurrently you must always create a new instance for each thread using newConnector(). Note, however, the ProjectConnection instances that a connector creates are completely thread-safe.
