Compiler options missing in Android Studio >= 0.8.2

Question

Recently I upgraded my Android Studio to 0.8.2. Now, my android-annotations based project fails to build. It seems like annotation processing is disabl

Answer 1

This is a little late, but for me, it's under

File -> Other Settings -> Default Settings -> Compiler

This compiler has dropdown options, including Annotation Processors.

Answer 2

In Android Studio 3.1.2 this setting is under:

File -> Other Settings -> Default Settings... -> Build, Execution, Deployment -> Compiler -> Java Compiler -> Additional command line parameters

Update

For more recent versions of Android Studio [tested on Android Studio 3.5 but probably starting from 3.4 according to Joel's comment] this setting is under:

File -> Other Settings -> Settings for New Projects... -> Build, Execution, Deployment -> Compiler -> Java Compiler -> Additional command line parameters

For existing projects it seems to me that the only option is to implement the solution described in these two answers A1 and A2, modifying the build.gradle file wrapping around allprojects or not based on your needs:

allprojects {
    gradle.projectsEvaluated {
        tasks.withType(JavaCompile) {
            options.compilerArgs << "-Xlint:unchecked" << "-Xlint:deprecation"
        }
    }
}
