Interface ProjectConnection
Represents a long-lived connection to a Gradle project. You obtain an instance of a ProjectConnection
by using GradleConnector.connect()
.
ProjectConnection connection = GradleConnector.newConnector() .forProjectDirectory(new File("someFolder")) .connect(); try { //obtain some information from the build BuildEnvironment environment = connection.model(BuildEnvironment.class) .get(); //run some tasks connection.newBuild() .forTasks("tasks") .setStandardOutput(System.out) .run(); } finally { connection.close(); }
Thread safety information
All implementations of ProjectConnection
are thread-safe, and may be shared by any number of threads.
All notifications from a given ProjectConnection
instance are delivered by a single thread at a time. Note, however, that the delivery thread may change over time.

Method Details
-
getModel
Fetches a snapshot of the model of the given type for this project. This method blocks until the model is available.This method is simply a convenience for calling
model(modelType).get()
- Type Parameters:
T
- The model type.- Parameters:
modelType
- The model type.- Returns:
- The model.
- Throws:
UnsupportedVersionException
- When the target Gradle version does not support the given model.UnknownModelException
- When the target Gradle version or build does not support the requested model.BuildException
- On some failure executing the Gradle build, in order to build the model.GradleConnectionException
- On some other failure using the connection.IllegalStateException
- When this connection has been closed or is closing.- Since:
- 1.0-milestone-3
-
getModel
<T> void getModel(Class<T> modelType, ResultHandler<? super T> handler) throws IllegalStateException Starts fetching a snapshot of the given model, passing the result to the given handler when complete. This method returns immediately, and the result is later passed to the given handler'sResultHandler.onComplete(Object)
method.If the operation fails, the handler's
ResultHandler.onFailure(GradleConnectionException)
method is called with the appropriate exception. SeegetModel(Class)
for a description of the various exceptions that the operation may fail with.This method is simply a convenience for calling
model(modelType).get(handler)
- Type Parameters:
T
- The model type.- Parameters:
modelType
- The model type.handler
- The handler to pass the result to.- Throws:
IllegalStateException
- When this connection has been closed or is closing.- Since:
- 1.0-milestone-3
-
newBuild
BuildLauncher newBuild()Creates a launcher which can be used to execute a build.Requires Gradle 1.0-milestone-8 or later.
- Returns:
- The launcher.
- Since:
- 1.0-milestone-3
-
newTestLauncher
Creates a test launcher which can be used to execute tests.Requires Gradle 2.6 or later.
- Returns:
- The launcher.
- Since:
- 2.6
-
model
Creates a builder which can be used to query the model of the given type.Any of following models types may be available, depending on the version of Gradle being used by the target build:
GradleBuild
BuildEnvironment
GradleProject
BuildInvocations
ProjectPublications
IdeaProject
BasicIdeaProject
EclipseProject
HierarchicalEclipseProject
A build may also expose additional custom tooling models. You can use this method to query these models.
Requires Gradle 1.0-milestone-8 or later.
- Type Parameters:
T
- The model type.- Parameters:
modelType
- The model type- Returns:
- The builder.
- Since:
- 1.0-milestone-3
-
action
Creates an executer which can be used to run the given action. The action is serialized into the build process and executed, then its result is serialized back to the caller.Requires Gradle 1.8 or later.
- Type Parameters:
T
- The result type.- Parameters:
buildAction
- The action to run.- Returns:
- The builder.
- Since:
- 1.8
-
close
void close()Closes this connection. Blocks until any pending operations are complete. Once this method has returned, no more notifications will be delivered by any threads.- Since:
- 1.0-milestone-3
