Grails : Error generating web.xml file

Question

I have upgraded my Grails project from version 2.1.2 to 2.2.3. Before the upgrade, the project worked flawlessly. However, I am not able to run the project now. I get a strange error :

| Compiling 143 source files.....
| Error Error generating web.xml file (Use --stacktrace to see the full trace)

and the compilation stops.

I thought that the "--stacktrace" option would provide some useful information. However, I am not able to decipher the error.

Error here > http://pastebin.com/zwR4YzXS

Googling / searching this problem did not help. I hope I am not the only one, who is getting this error.

Thank you for your advices !

If you are using Intellij the problem is that: the reason for this is that IDEA adds classpath by default on creating integration test run configuration. So if you run tests you might cause that error

Open Run → Edit Configurations... (or press Alt-Shift-F10) Select your configuration that fails Uncheck Add --classpath checkbox You are done! Run.
