This issue is motivated by an issue that a user raised a while back with STS tooling here:

Note: the wording 'aggregated task' is terminology that I am not sure is actually correct 'Gradle Speak'. But I hope the description is clear enough.

Essentially, I think what the user is poiting out is that we don't have a mechanism to do something like "run all tasks called 'test' on all this project's subprojects".

I could imagine an option checkbox in the STS UI that says 'show aggregated tasks'. When selected, we would show the union of the names of all tasks on a given project and all of its subprojects, and when such an 'aggregated task' is executed it would actually execute the task with that name on all projects.

I could probably implement this kind of task agregation on the STS side, but I'm reluctant to do so because I recall talking with some of you guys a while back and, I believe, you were saying this is something Gradle already knows how to do (and I would fear if STS is doing it, it may not be equivalent or correct when it comes the analyzing task dependency and deciding task execution order).

Thus I think it would be best if the Tooling API would provide some kind of way to retrieve a list of aggregated tasks and execute an aggregated task.

Please excuse me if the term 'agregated tasks' is incorrect, feel free to correct me

Now available via http://www.gradle.org/docs/nightly/javadoc/org/gradle/tooling/model/gradle/BuildInvocations.html model as TaskSelector instances. Those can be used to run a build using

projectConnection.newBuild().forLaunchables(selector1, selector2, ...)
