Question

I am attempting to add a maven repository to my Android Studio project. When I do a Gradle project sync everything is fine. However, whenever I try to build my apk, I get this e

Answer 1

Add this in defaultConfig

android.defaultConfig.javaCompileOptions.annotationProcessorOptions.includeCompileClasspath = true

Answer 2

I was with a similar error. I follow the instructions on the Google link and it works.

try to add the follow instructions to your app gradle file:

defaultConfig {
    applicationId "com.yourdomain.yourapp"
    minSdkVersion 17
    targetSdkVersion 25
    versionCode 1
    versionName "1.0"

    javaCompileOptions {
        annotationProcessorOptions {
            includeCompileClasspath = false
        }
    }
}

Attention to -> includeCompileClasspath false

Answer 3

If you have dependencies on the compile classpath that include annotation processors you don't need, you can disable the error check by adding the following to your build.gradle file. Keep in mind, the annotation processors you add to the compile classpath are still not added to the processor classpath.

 android {
    ...
    defaultConfig {
        ...
        javaCompileOptions {
            annotationProcessorOptions {
                includeCompileClasspath false
            }
        }
    }
}

If you are experiencing issues migrating to the new dependency resolution strategy, you can restore behavior to that of Android plugin 2.3.0 by setting includeCompileClasspath true. However, restoring behavior to version 2.3.0 is not recommended, and the option to do so will be removed in a future update.
