I have an android project with both java and kotlin files.

After compilation, when I unzip the generated apk file, I can see all the Kotlin files of my project in their package path.
The Java files however are not present.

How can I fix this, and stop the Koltin files from beeing added to the apk ?

Thanks

My build.gradle:

buildscript {

    ext.kotlin_version = '1.2.71'

    repositories {

        jcenter()

        maven { url 'https://maven.fabric.io/public' }

        google()

    }

    dependencies {

        classpath 'com.android.tools.build:gradle:3.1.3'

        classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:$kotlin_version"

    }

            def relativeRootDir = output.packageApplication.outputDirectory.toPath()

                    .relativize(rootDir.toPath()).toFile()



            output.outputFileName = new File("$relativeRootDir/$dir", name)

        }

    }

}

Finally found the issue:

I had to removed resources.srcDirs = ['src'] from the sources set

This was copying all non-java files contains under the src folder
