Android Studio 3.0 Canary 1 annotation processor error

Question

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'
compile 'com.squareup.retrofit2:retrofit:2.1.0'
compile 'com.squareup.retrofit2:converter-gson:2.1.0'
compile 'com.squareup.okhttp3:logging-interceptor:3.2.0'
compile 'com.jakewharton.timber:timber:4.4.0'
compile 'io.reactivex:rxandroid:1.0.1'
compile 'io.reactivex:rxjava:1.0.14'
compile 'com.squareup.retrofit2:adapter-rxjava:2.1.0'
compile 'com.jpardogo.googleprogressbar:library:1.2.0'
compile 'com.wang.avi:library:2.1.3'
compile 'link.fls:swipestack:0.3.0'
compile 'com.jakewharton:butterknife:8.4.0'
compile 'com.codemybrainsout.rating:ratingdialog:1.0.7'
compile 'org.greenrobot:greendao:3.2.0'
compile 'com.android.support.constraint:constraint-layout:1.0.0-beta5'
testCompile 'junit:junit:4.12'
annotationProcessor 'com.jakewharton:butterknife-compiler:8.4.0'
provided 'org.projectlombok:lombok:1.12.6'

Answer 1

Turns out Lombok and Butterknife were causing issues

I updated ButterKnife and added annotationProcessor for Lombok which solved the issue

implementation 'com.jakewharton:butterknife:8.6.0'
annotationProcessor 'com.jakewharton:butterknife-compiler:8.6.0'

compileOnly 'org.glassfish:javax.annotation:10.0-b28'
compileOnly "org.projectlombok:lombok:1.16.16"
annotationProcessor "org.projectlombok:lombok:1.16.16"

Update

As per @Beshoy's comment below changed compile to implementation and provided to compileOnly

Answer 2

see the error message after compiling. it will show the package name which need Annotation process. for example:

Error:Execution failed for task ':MPChart_libary:javaPreCompileDebug'.
> Annotation processors must be explicitly declared now.  The following dependencies on the compile classpath are found to contain annotation processor.  Please add them to the annotationProcessor configuration.
    - realm-android-0.87.5.jar
  Alternatively, set android.defaultConfig.javaCompileOptions.annotationProcessorOptions.includeCompileClasspath = true to continue with previous behavior.  Note that this option is deprecated and will be removed in the future.
  See https://developer.android.com/r/tools/annotation-processor-error-message.html for more details.

search name "realm-android-0.87.5" in build.gradle file of Module "MPChart_libary":

dependencies {
    provided 'io.realm:realm-android:0.87.5' 
}

fix build.gradle file as following:

dependencies {
    provided 'io.realm:realm-android:0.87.5' 
    annotationProcessor 'io.realm:realm-android:0.87.5' //fix here
}
