After update Android Studio to 2.3 version I have warning:
Warning:Using incompatible plugins for the annotation processing: android-apt. This may result in an unexpected behavior.
Any solutions? My app stopped working...
Your app level gradle dependencies should include (as per butterknife website instructions):
compile 'com.jakewharton:butterknife:8.8.1'
annotationProcessor 'com.jakewharton:butterknife-compiler:8.8.1'
You can remove the line :
apply plugin: 'com.neenbedankt.android-apt'
Annotation Processing became available in Android Gradle plugin (2.2 and later) so there is now no need to use the above plugin anymore if using this version of gradle or greater.
If you'd like to know how to turn annotation processing off and on and AS the setting is in :
Settings > Build, Execution, Deployment > Compiler > Annotation Processors
In my project I use, among other things, Butter Knife and Immutables. After adding Immutables I got the following warning
Warning:Using incompatible plugins for the annotation processing: android-apt. This may result in an unexpected behavior.
and ButterKnife stopped working.
My configuration was as follows:
build.gradle (Project: MyApplication)
buildscript {
repositories {
jcenter()
}
dependencies {
classpath 'com.android.tools.build:gradle:2.3.1'
classpath 'com.neenbedankt.gradle.plugins:android-apt:1.8'
}
}
build.gradle (Module: app)
apply plugin: 'com.android.application'
apply plugin: 'android-apt'
...
dependencies {
...
// Butter Knife
compile 'com.jakewharton:butterknife:8.5.1'
annotationProcessor 'com.jakewharton:butterknife-compiler:8.5.1'
// Immutables
apt 'org.immutables:value:2.4.4'
provided 'org.immutables:value:2.4.4'
provided 'org.immutables:builder:2.4.4'
provided 'org.immutables:gson:2.4.4'
}
After changing
annotationProcessor 'com.jakewharton:butterknife-compiler:8.5.1'
to
apt 'com.jakewharton:butterknife-compiler:8.5.1'
warning disappeared and everything works as it should.
UPDATE
As Mark said, an annotation processor was included in the Gradle version 2.2 , so there is no reason to provide an extra one.
So:
1) Remove the class path for the apt from the build.gradle (Project: MyApplication)
classpath 'com.neenbedankt.gradle.plugins:android-apt:1.8'
2) Remove the plug in from the build.gradle (Module: app)
apply plugin: 'android-apt'
3) Change the dependencies from apt to the new annotationProcessor
annotationProcessor 'com.jakewharton:butterknife-compiler:8.5.1'
annotationProcessor 'org.immutables:value:2.4.4'
To add to @Milan's answer, if you used the hotchemi permissiondispatcher library in your app level gradle file then you should replace it as follows:
Replace
apt 'com.github.hotchemi:permissionsdispatcher-processor:2.4.0'
with
annotationProcessor 'com.github.hotchemi:permissionsdispatcher-processor:2.4.0'
