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

I had same issue when I migrated gwt from 2.6.1 to 2.8. Actually this error caused by asm dependency. Some of your server dependency has internal dependency to asm. In my case its cglib. So I changed cglib to cglib-nodep and it worked :-)

   
        cglib
        cglib-nodep
        3.2.1
