Annotation Processor -source '1.8' causes Execution failure

[dgngulcan]

When annotationProcessor 'org.parceler:parceler:1.1.8' line added to gradle file, I get the error below. Without it, build is successful.

Warning:Supported source version 'RELEASE_7' from annotation processor 'android.arch.lifecycle.LifecycleProcessor' less than -source '1.8' Error:Execution failed for task ':app:compileDebugJavaWithJavac'. java.lang.NullPointerException

Strange, since Parceler should support Java 1.8 (Or "latestSupported") Any clue what the system property java.specification.version value is?

[johncarl81]

Also, can you provide an example of this issue so I can diagnose and fix?

[dgngulcan]

I am using Android Studio 3.0 preview with the embedded JDK comes in it. Tried with Oracle JDK but didn't make difference.

The build is successful when I remove the line annotationProcessor 'org.parceler:parceler:1.1.8'

But with it, it gives the error

Warning:Supported source version 'RELEASE_7' from annotation processor 'android.arch.lifecycle.LifecycleProcessor' less than -source '1.8'

[johncarl81]

When I change the source compatibility I get a slew of errors from Android. I don't believe Android is compatible with Java 1.8, isn't that correct?

[dgngulcan]

It is not fully compatible but some functions can be used as written https://developer.android.com
