dagger: Dagger 2.10-rc1 won't compile in Android

I wanted to try the new features for activity and fragment injection in dagger.android but I get this gradle error stack trace when trying to update from v2.9 -> 2.10-rc1

warning: Ignoring InnerClasses attribute for an anonymous inner class (autovalue.shaded.org.apache.commons.lang.builder.HashCodeBuilder$1) that doesn’t come with an associated EnclosingMethod attribute. This class was probably produced by a compiler that did not target the modern .class file format. The recommended solution is to recompile the class from source, using an up-to-date compiler and without specifying any “-target” type options. The consequence of ignoring this warning is that reflective operations on this class will incorrectly indicate that it is not an inner class. warning: Ignoring InnerClasses attribute for an anonymous inner class (autovalue.shaded.org.apache.commons.lang.builder.ToStringStyle$1) that doesn’t come with an associated EnclosingMethod attribute.

It’s not a Retrolambda problem. The classfiles in the artifact were compiled with a target of Java 8.

That syntax is invalid so I suspect your build is not actually picking up the new artifacts. Try this:

compile "com.google.dagger:dagger:${dagger2}"
compile "com.google.dagger:dagger-android:${dagger2}"
compile "com.google.dagger:dagger-android-support:${dagger2}"

annotationProcessor "com.google.dagger:dagger-compiler:${dagger2}"
annotationProcessor "com.google.dagger:dagger-android-processor:${dagger2}"

Should be live (but Sonatype seems slow today)

I think I found my error. I mistakenly thought that my hand-built Dagger Android libraries were the issue, when the real problem was the official plain dagger RC1 artifact from Maven. Thanks for the pointer!
