Erhard Weinell created CXF-5286:
-----------------------------------

             Summary: Lengthy done-file names raise mojo exception
                 Key: CXF-5286
                 URL: https://issues.apache.org/jira/browse/CXF-5286
             Project: CXF
          Issue Type: Bug
    Affects Versions: 2.7.6, 2.7.7
            Reporter: Erhard Weinell


Done-file names can become quite long, even going beyond the allowed 256 chars on common file systems. Up until (at least) cxf-2.2, the resulting IOException has been logged as warning with no further consequences. In the most current releases, a MojoExecutionException is raised besides that. 

C.f. {{org.apache.cxf.maven_plugin.wsdl2java.WSDL2JavaMojo.generate(GenericWsdlOption, Bus, Set<URI>)}}

Is this intended behavior? 
* If so, I suggest an improved way to shorten these filenames, as the current algorithm just strips the project directory if part of the file path. I would prefer stripping common prefixes of these paths instead. I can provide a 2-line patch if desired. 
* If the behavior is not intended, I would argue raising this exception - which in addition differs from its super-class implementation, should be reverted. 

Best regards,
 Erhard Weinell
