在Gradle插件中获取项目源目录

Question

First of all sorry if I've missed this in the documentation somewhere.

I'm trying to write a Gradle plugin in Java.

More specifically I need to do this:

public class MyPlugin implements Plugin<Project>{

    @Override
    public void apply(Project project) {
        project.getSourceDir();
    }
}

In other words, how can I, if possible, get the directory where the sources of the project my plugin is run over reside?

Am I correct in my assumption that when the apply method gets called Gradle will already know where the sources are and this location can not change further on?

Thanks.

Answer 1

Yes because the plugin is applied to a Project per your parameter. If you "apply" it to two projects then it creates two instances of the plugin and pass your project objects to the apply method.

Answer 2

Look through the Gradle user guide.

A project has a list of "sourceSet" objects, which you get to with "project.sourceSets". Each sourceSet has a set of properties.

It's good to browse through The DSL reference to see what properties are available. Look for "SourceSet".
