Android Studio error: Execution failed for task ':app:processDebugResources'

Question

Opened a project I haven't touched in like two months to make a slight update and after updating Android Studio I am not able to compile the code without the following error.

I have been googling this for the past two hours and cannot resolve it. I have tried pretty much everything in the other similar threads including changing my compileSdkVersion to 28 amongst others.

Full error message:

FAILURE: Build failed with an exception.

* What went wrong:
Execution failed for task ':app:processDebugResources'.

Answer 1

Maybe problem in

implementation 'com.github.turing-tech:MaterialScrollBar:13.+'

I go to github and look to this lib build gradle file:

    def libVersion = '13.3.2'

android {
    compileSdkVersion 28
    buildToolsVersion '28.0.3'

    defaultConfig {
        minSdkVersion 14
        targetSdkVersion 28
        versionName libVersion
    }
    compileOptions {
        sourceCompatibility JavaVersion.VERSION_1_8
        targetCompatibility JavaVersion.VERSION_1_8
    }
}

i see

buildToolsVersion '28.0.3'

but in you project:

27.1.1

Try to set more older version for lib, just add

implementation 'com.github.turing-tech:MaterialScrollBar:13.3.0'

instead this

implementation 'com.github.turing-tech:MaterialScrollBar:13.+'
