Manual execution of build task

[eugene.m...@gmail.com]

Hi,

I have a task that needs to do some work before calling build itself. And I wanted to call build manually from that task. Accordingly to what I have found it can be done with something like this:

task someTask << {

    ...

    tasks['build'].execute()

    ...

}

But it does not trigger build at all. Though the same way of calling tasks works fine with the tasks declared inside build.gradle.

Am I missing something here?

P.S. I was able to trigger build by placing dependsOn inside task declaration

task someTask(dependsOn : 'build') << {

...

}

but it is not what I am looking for

There's a task called "preBuild" that is run before all other tasks, so you could do the following:

task someTask << {

}

preBuild.dependsOn someTask

This ensures that your task is always run before a build.

Hi, 

I may be missing something, but as far as I remember, executing tasks with execute() method executes only task itself, not its task dependencies.

Besides, execute() is internal api of org.gradle.api.internal.AbstractTask

http://www.gradle.org/docs/current/javadoc/org/gradle/api/DefaultTask.html

Yes, calling execute() on tasks is not supported in any way.

Gradle is always in control of deciding when to execute tasks (i.e. via dependsOn, mustRunAfter, finalizedBy etc.) and not the build script author. Therefore, it makes no sense to try and programatically execute a task.
