Downgrade butterknife-gradle-plugin to 8.4 or use 9.0 snapshot.
In my library project this comment helped me (R2 imports): https://github.com/JakeWharton/butterknife/issues/963#issuecomment-342547601
project's build.gradle:
buildscript {
repositories {
maven { url "https://oss.sonatype.org/content/repositories/snapshots" }
google()
jcenter()
}
dependencies {
classpath 'com.jakewharton:butterknife-gradle-plugin:9.0.0-SNAPSHOT'
}
}
repositories {
maven { url "https://oss.sonatype.org/content/repositories/snapshots" }
}
module's build.gradle:
apply plugin: 'com.jakewharton.butterknife'
...
dependencies {
compile 'com.jakewharton:butterknife:9.0.0-SNAPSHOT'
kapt 'com.jakewharton:butterknife-compiler:9.0.0-SNAPSHOT'
}
This way you can use the
apply plugin: 'com.jakewharton.butterknife'
Just remove
classpath 'me.tatarka:gradle-retrolambda:3.7.0'
downgrade butterknife
version to 8.4.0
classpath 'com.jakewharton:butterknife-gradle-plugin:8.4.0'
Don't forget to remove below line
apply plugin: 'me.tatarka.retrolambda'
