I want to start the build task from a new task I’m creating. How do I do this?

I don’t quite understand what you are asking for.

I want to create a new task and have one of the things that the task does be starting a build.

Does the org.gradle.api.tasks.GradleBuild task do what you need?

I’m not sure how to use that. I’ve set my task as type GradleBuild but the build doesn’t start.

OK, I think I’ve got it now:

```gradle
task release(type: GradleBuild) {
    tasks = ['build']
}

```

So is this working for you now Jordan?

Yes - it does what I want. I’m not sure, though, if there’s a better way.

(Gradle newbie here)

I’m curious about Jordan’s solution - does the following snippet do the same thing? (except that the build task would run before the release task)

```gradle
task release(type: GradleBuild, dependsOn: build) {
}

```

Shorn - that generates an error. I’m not sure why.

Shorn, no they are two different things.

The org.gradle.api.tasks.GradleBuild task is for launching a separate Gradle process during a Gradle build. So if you need to build a completely separate Gradle project from another Gradle project it’s useful.

If you’re trying to create a task named “release” that just _triggers_ the “build” task in the same build, you just need:

task release(dependsOn: build)

Does that explain the difference?

Oh, yes - I see now (I didn’t realise what the GradleBuild task was doing).

Cheers.
