Re: GWT 2.6.0 to 2.7.0 leads to compiler error 'java.lang.IncompatibleClassChangeError'

Thanks for the hint. It was an old ASM version.
Now it builds fine.

 Hi,
 find out which dependency is including ASM and then try to exclude it in 
 your pom.xml

 In our project,  app-hmi-soaconnector was importing ASM as a 
 sub-dependency due to CXF, so It did added the exclusion tag like you can 
 see below directly in our main GWT web app project.

GWT 2.6.0 to 2.7.0 leads to compiler error 'java.lang.IncompatibleClassChangeError'

2014-12-02 Thread Stephan Beutel 
Hello,

after switching to GWT 2.7.0 I cannot build our project anymore. I cleaned 
everything in my Maven target folder (gwt unit cache, build classes, ...) 
but with no luck.

Every time I get this stacktrace:
