AndroidStudio says Error:Execution failed for task ':app:processDebugResources' - gradle

Question

I get the following error, while compiling / building my app with AndroidStudio 1.4:
Error:Execution failed for task ':app:processDebugResources'.>
com.android.ide.common.process.ProcessException:
org.gradle.process.internal.ExecException: Process 'command
'/home/pepperonas/Android/Sdk/build-tools/23.0.2/aapt'' finished with
non-zero exit value 1
Who knows what causes this issue? I spent a lot of time trying different gradle versions and configurations, but the error is raised again.
This is how my gradle looks like:
buildscript {
repositories {
jcenter()
}
dependencies {
classpath 'com.android.tools.build:gradle:1.5.0'
}
}
apply plugin: 'com.android.application'

Answer 1

Got it. The issue comes from the two FAB-libraries I added to the project.
compile 'com.melnykov:floatingactionbutton:1.2.0'
compile 'com.github.clans:fab:1.6.1'
I guess some resources are named the same ("duplicate").
