How to upload Archives for several modules by using gradle?

Question

I want to publish my SDK in maven with $ ./gradlew uploadArchives

I had this project structure:

MyProject

  |_ SDK
     |_ src
         |_ main
              |_ java
                   |_ java files
     |_ build.gradle
  |_ gradle
        |_ gradle-publish.gradle

I used following code (gradle-publish.gradle) that works as expected:

task androidJavadocsJar(type: Jar, dependsOn: androidJavadocs) {
    classifier = 'javadoc'
    from androidJavadocs.destinationDir
}

task sourcesJar(type: Jar) {
    classifier = 'sources'
    from android.sourceSets.main.java.sourceFiles
}

uploadArchives {
    repositories {
        mavenDeployer {
         /* ... */
        }
    }
}

artifacts {
    archives sourcesJar
    archives androidJavadocsJar
}

Now I splitted main module to 2: SDK and new_module so my project structure looks like:

MyProject

  |_ SDK
     |_ src
         |_ main
              |_ java
                   |_ java files  "com.app"
     |_ build.gradle

 |_ new_module
     |_ src
         |_ main
              |_ java
                   |_ java files "com.app.mod"
      |_ build.gradle
  |_ gradle
        |_ gradle-publish.gradle

However no matter what I do, I always get only SDK sources and not new_module a.e. com.app should be merged with com.app.mod

I tried to play with sourceSets but it looks like it works inside main module SDK and not under root project:

sourceSets {
    main{
      java {
        srcDirs(
                "src/main/java",
                 "../new_module/src/main/java"
        )
    }
}

and:

task sourcesJar(type: Jar) {
   classifier = 'sources'   
   from android.sourceSets.main.java.srcDirs    
}

Any ideas, tips?

Edit

I added

sourceSets {
    main{
      java {

        srcDirs("src/main/java",
                "${root_dir}/new_module/src/main/java"
        )
      }
    }
  }

However on maven I see all have sources but classes.jar contains only app .class files

Answer 1

Add custom sourceSet under android section of your SDK build.gradle:

android{
    //...
    sourceSets {
        main{
            java {
                srcDirs "$rootDir/new_module/src/main/java/"

            }
        }
    }
}

You don't need include "src/main/java" - its already included

Also you don't need bind new_module into your dependancies, new_module will be a part of your SDK module

task androidSourcesJar(type: Jar) {
    classifier = 'sources'
    from android.sourceSets.main.java.sourceFiles
  }

Answer 2

Check this link it's intended for distribution through Jcenter, follow the steps mentioned in the link for each of your submodules.

And make sure all your submodules are published to the same remote with a common GROUP_ID.
