Error:warning: Ignoring InnerClasses attribute for an anonymous inner class

[jackdh]

Hey,

I'm getting this warning from Gradle when I run the application.
(Putting it in a gist as it's quite long)

My pro guards file is currently empty.

This is my build.gradle

apply plugin: 'android-apt'

    compileSdkVersion 25

    defaultConfig {
        multiDexEnabled true

        testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"

    }
    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'

        }
    }

I see that in other Android projects as well, it seems to be related to inner classes and did not seem to cause any actual harm when running those applications.

Also the warnings are about code that are not compiled as part of this project, i.e. com.bea.xml.stream and org.apache.xmlbeans and thus there is likely not much that can be done about as it would require recompilation from source of those third party dependencies.

[jackdh]

I see is there a way to mute these warnings just for those dependencies?

Closing as not really related to the workaround itself.
