Method Detail

• getModel

  <T> T getModel​(java.lang.Class<T> modelType)
          throws UnknownModelException

  Fetches a snapshot of the model of the given type for the default project. The default project is generally the project referenced when a ProjectConnection is created.

  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.

  Type Parameters:

  T - The model type.

  Parameters:

  modelType - The model type.

  Returns:

  The model.

  Throws:

  UnknownModelException - When the default project does not support the requested model.

• getModel

  <T,​P> T getModel​(Model target,
                         java.lang.Class<T> modelType,
                         java.lang.Class<P> parameterType,
                         Action<? super P> parameterInitializer)
                  throws UnsupportedVersionException,
                         UnknownModelException

  Fetches a snapshot of the model of the given type for the given element using the given parameter.

  The parameter type must be an interface only with getters and setters and no nesting is supported. The Tooling API will create a proxy instance of this interface and use the initializer to run against that instance to configure it and then pass to the model builder.

  See getModel(Class) for more details.

  Type Parameters:

  T - The model type.

  P - The parameter type.

  Parameters:

  target - The target element, usually a project.

  modelType - The model type.

  parameterType - The parameter type.

  parameterInitializer - Action to configure the parameter

  Returns:

  The model.

  Throws:

  UnknownModelException - When the target project does not support the requested model.

  UnsupportedVersionException - When the target project does not support the requested model or Gradle version does not support parameterized models.

  Type Parameters:

  T - The model type.

  P - The parameter type.

  Parameters:

  target - The target element, usually a project.

  modelType - The model type.

  parameterType - The parameter type.

  Returns:

  The model.

• run

  <T> java.util.List<T> run​(java.util.Collection<? extends BuildAction<? extends T>> actions)

  Runs the given actions and returns their results. Attempts to run the actions in parallel, when supported by the Gradle version.

  This method works with all Gradle versions. For versions 6.7 and earlier, the actions are run sequentially rather than in parallel.

  When one or more actions fail with an exception, the exceptions are rethrown by this method and no result is returned.

  Type Parameters:

  T - the result type.

  Parameters:

  actions - The actions to run.

  Returns:

  The action results. These are returned in the same order as the actions that produce them.

  6.8

• getCanQueryProjectModelInParallel

  boolean getCanQueryProjectModelInParallel​(java.lang.Class<?> modelType)

  Returns true when actions run using run(Collection) and that query project models of the given type will run in parallel. Returns false when the models will not be queried in parallel, for example because the target Gradle version does not support parallel execution, or because some build configuration disables the parallel execution, or because the queries are unsafe to perform in parallel.

  Returns:

  true when project models may be queried in parallel.

  Since:

  6.8

• send

  @Incubating
  <T> void send​(T value)

  Streams an object to the client application.

  The client application can receive objects sent using this method by registering a StreamedValueListener. The client application receives objects in the order they were sent, and before it receives the result of the BuildAction.

  This method sends the object asynchronously and does not block until the client application has received the object.

  The build action will fail if the client application did not register a listener to receive the streamed objects.
