怎么在Gradle中编译.so库

There is a topic we known as: "https://gist.github.com/khernyo/4226923", But i have try this method in gradle plugin 0.4.0+, it doesn't copy the so libs to apk.
So I'm confused. But I figured out a new way to hack this before gradle support.
The way is: use jar to copy so libs. Is it amazing?right?. Let me show how-to:
If you have the following structure:
project
|---libs
      |---armeabi/xxx.so
      |---xxx.jar
      |---xxx.jar
1.We archive the armeabi folder to zip named:armeabi.zip with the folder in zip like: lib/armeabi/xxx.so
2.Rename armeabi.zip to armeabi.jar and put armeabi.jar into libs folder with the other jars.
3.And when we call
dependencies {
compile fileTree(dir: 'libs', include: '*.jar')
}
in our build.gradle file, it will extract the so libs to the apks.
