How to build 1 jar of 3 submodules using gradle

Question

I have:

• Android Studio 3
• gradle 4.1
• gradle tools 3: classpath 'com.android.tools.build:gradle:3.0.1'

When I had one module and gradle 2 tools were used, I used:

task makeJar(type: Copy) {
    def releaseFolder = new File('build/intermediates/bundles/release/')
    if (releaseFolder.exists()) {
        from('build/intermediates/bundles/release/')
    } else {
        from('build/intermediates/bundles/default/')
    }
    into('build/outputs/jar/')
    include('classes.jar')
    rename ('classes.jar', 'MY-Android-SDK.jar')
}

---

You now have 3 modules:

              MainModule (com.my)
                 /   \
(com.my.m1) Module1   Module2 (com.my.m2)

I want to create a MY-Android-SDK.jarfile from all three modules .

So far I can create 3 jar files for each module and somehow combine them, but I believe that this is not the right way to do this.

Any ideas?

Answer 1

First of all, if you are creating Android libraries, create an AAR, not a JAR. AAR files follow the structure of the android SDK and can have manifest files and therefore require permission and xml resources, among other things.

settings.gradle

settings.gradle

rootProject.name = 'MainModule'
include 'module2'
include 'module3'

build.gradle, MainModule, :

build.gradle

configurations {
    modules
    compile.extendsFrom(modules)
}

dependencies{
    modules project(':moudle2')
    modules project(':moudle3')
}

task packageAll(type: Jar) {
    manifest {
        attributes 'Main-Class': 'YourMainClass'
    }

    // pack yours main module
    from sourceSets.main.output

    // pack your other two modules
    from {
        configurations.modules.collect { it.isDirectory() ? it : zipTree(it) }
    }

    // pack all dependencies in the project
    from configurations.compile.collect { it.isDirectory() ? it : zipTree(it) }

    version = ""
    baseName = "MY-Android-SDK"
}
