Just upgraded to Android Studio 3.0, a project which was compiling before is throwing following error

Error:java.lang.RuntimeException: Annotation processors must now be declared explicitly. The following dependencies in the compile classpath are found to contain annotation processors. Please add them to the annotationProcessor configuration.

However, this following is not defined. here is how compile statements in my build.gradle looks like

compile('com.crashlytics.sdk.android:crashlytics:2.6.7@aar') {
    transitive = true;
}

compile 'com.android.support:support-v4:25.3.1'
compile 'com.android.support:appcompat-v7:25.3.1'
compile 'com.android.support:design:25.3.1'

  1. Open build.gradle of project

  2. Just add these line in defaultConfig :

     javaCompileOptions {
                annotationProcessorOptions {
                      includeCompileClasspath true
                  }
             }

I have same problem with MPchart library, in build.gradle of MPchart project add this:

defaultConfig {
        ...
        javaCompileOptions {
            annotationProcessorOptions {
                includeCompileClasspath true
            }
        }
    }

Make sure that in your app gradle file you use:

annotationProcessor

instead of

implementation or compile

It's easier and faster,

e.g.

dependencies {

    //BUTTERKNIFE
    implementation 'com.jakewharton:butterknife:8.8.1'
    annotationProcessor 'com.jakewharton:butterknife-compiler:8.8.1'

}
