generateRJava function failing due to non existent dependencies.

Hi,

I am facing an issue when trying to assemble a release variant due to the generateRJava in fat-aar.gradle. Below is the exception: C:\Mobile 3.7 Android\testproj\build\generated\source\r\release\com\eye\R.java:1264: error: cannot find symbol public static int Theme_popupMenuStyle = com.company.mobile.android.sdk.activity.R.styleable.Theme_popupMenuStyle; ^ symbol: variable Theme_popupMenuStyle location: class styleable Note: Some input files use or override a deprecated API. Note: Recompile with -Xlint:deprecation for details. Note: Some input files use unchecked or unsafe operations. Note: Recompile with -Xlint:unchecked for details. 100 errors :testproj:compileReleaseJavaWithJavac FAILED

• What went wrong: Execution failed for task ':testproj:compileReleaseJavaWithJavac'.

  Compilation failed; see the compiler error output for details.

BUILD FAILED

I think that this might be because fat aar is generating the R.java for the aar's that I am trying to embed. This is creating the dependencies that are not being resolved. Also when I comment out the code in generateRJava everything works fine.

Another observation, there are 2 aar's that we are trying to embed, one of them doesnt have a R.java file, I saw this when I opened the exploded AAR. Maybe this is causing some issue.

One more question: In the below part of the code, the R.java is getting generated. This is where the project expects the variable that is in the aar to be in my project also. Why is this being done?

// Generate the R.java file and map to current project's R.java // This will recreate the class file def rTxt = file("$aarPath/R.txt") def rMap = new ConfigObject()

if (rTxt.exists()) {
  rTxt.eachLine {
    line ->
      //noinspection GroovyUnusedAssignment
      def (type, subclass, name, value) = line.tokenize(' ')
      rMap[subclass].putAt(name, type)
  }
}

def sb = "package $aarPackageName;" << '\n' << '\n'
sb << 'public final class R {' << '\n'

rMap.each {
  subclass, values ->
    sb << "  public static final class $subclass {" << '\n'
    values.each {
      name, type ->
        sb << "    public static $type $name = ${libPackageName}.R.${subclass}.${name};" << '\n'
    }
    sb << "    }" << '\n'
}

sb << '}' << '\n'

@siddpande Hi,did you solved this already?any idea?Thanks~

No, had to move away from fat arr due to this issue.

you can filter none exist id，hope this will help you `task generateRJava << { println "Running FAT-AAR Task :generateRJava"

// Now generate the R.java file for each embedded dependency
