While not only a GWT question, I thought this was the best place to ask. I've got an GWT 2.7 application which is being upgraded to 2.8. I'm using one of the latest snapshot (2.8.0-269) together with Guava (20.0.220-SNAPSHOT).
The problem is I get the same type of error that is mentioned in this issue: https://github.com/gwtproject/gwt/issues/9323, but just adding both error_prone_annotations and j2objc-annotations jars to the classpath when running the CodeServer doesn't seem to work for me. I did get it working by manually adding a GWT module file (Annotations.gwt.xml) to both jars, which just sets the source path: <module> <inherits name="com.google.gwt.core.Core" /> <source path=""/> <source path="concurrent"/> <super-source path="super" /> </module> And then add then reference this in my main Module file: <inherits name="com.google.errorprone.annotations.Annotations" /> <inherits name="com.google.j2objc.annotations.Annotations" /> But I would like to avoid manually modifying those jars (as that makes each upgrade more of a pain, and I need to upload the modified jars to our maven repository instead of just mirroring the existing ones). Anyone have any idea what I'm missing? -- You received this message because you are subscribed to the Google Groups "GWT Users" group.
