在build.gradle中编译的选择性模块

Question

is there a way to selectively compile modules per flavor?

I am trying to reduce build time in development by not compile various modules when running debug flavor.

in Eclipse, I would not put them in the libs folder and instead put them in the addon-libs and compile them only when exporting (via a gradle build script) and in the code have something like this:

try {
   if(Class.forName(clazz) {
      doStuffForLib();
   }
} catch (ClassNotFoundException ex) {
   // DO NOTHING
}

my question is, can I do something similar in my build.gradle now and reduce build time some more?

ie, I would write something like this

buildTypes {
   debug{
   }

   release {
      compile 'some.module:version:1.+'
   }
}

Answer 1

You can achieve it with flavors or buildTypes using.

dependencies {
    flavor1Compile xxx
    debugCompile xxxx
}

Answer 2

After searching around I found this JIRA ticket that fixed my issue.

You can supply compiles per version and use the provided dependency task for the others while maintaining the code provided for avoiding use of modules that weren't compiled when they aren't present as such

public boolean isClassFound(String clazz) {
    try {
        return Class.forName(clazz);
    } catch (ClassNotFoundException e) {
        e.printStackTrace();
    }
    return false
}

And in the build.gradle add:

dependencies {
    provided 'some.module:version:1.+'
    releaseCompile 'some.module:version:1.+'
}
