推荐答案

首先，该代码不起作用，因为它仅适用于带有Java gradle插件的Java项目.所以我搜索了一下，发现有一些解决方法. 这是我的代码.

First,the code doesn't work because it's only for the java project with java gradle plugin. So I googled and found something work around. Here is my code.

project.afterEvaluate {
    ...
    def sets;
    if (Utils.is140orAbove()) {
        sets = project.android.sourceSets;
    } else {
        sets = project.android.sourceSetsContainer;
    }
    sets.all { AndroidSourceSet sourceSet ->
        if(sourceSet.name.startsWith("main"))
            for(File file:sourceSet.java.getSrcDirs())
                if(file.exists()) {
                    mainSource = file;
                    break;
                }
    }
    ...
}

我的代码不漂亮.正在等待更好的答案.

My code is not beautiful.Waiting for better answer.
