GWT Compilation Error - IncompatibleClassChangeError

Question

When compiling the project, I get this obscure Exception

Looking for precompiled archives.  To disable, use -Dgwt.usearchives=false
Loading archived module: jar:         


        

Answer 1

Please try it again after removing all the generated stub and re-compiling the project again.

I have highlighted all the stubs that needs to be deleted as shown in below snapshot.

Here is the list of folders (name can vary based on your GWT project compilation module name) that need to be removed.

• gwt-unitCache
• test-classes
• war > gwtproject
• war > WEB-INF > classes
• war > WEB-INF > deploy
