I'm getting this "Execution failed for task 'app:mergeDebugResource'" error every time I try to build or clean my project. I have reinstalled Gradle, Java, Android Studio, and all of the SDKs several times, so it's not that. And none of the answers on StackOverflow seem to be helpful. I'm trying to learn Android development but can't because of this error. Please help!
Here are the results of Gradle build --stacktrace:
