Bug report webby plugin for eclipse

[MadJlzz]

Hello,

I am having trouble using the new Eclipse Luna 4.4 SR1 with my m2e plugins. The thing is that when I am saving a JSP file (or whatever) followed by a project build (Project > Build Project), eclipse raised an exception that I really don’t unterstand. It happens when I am copying files from one project to another too.

I’ve searched for hours but I didn’t fight the right answer of my questions in the web so I thought you could help me.

Have a look at the stack trace :

I think you are hitting issue #6 that was fixed recently by @pascalleclercq

Please reinstall the plugin from this update site and check if it helps: http://repository.takari.io:8081/nexus/content/sites/m2e.extras/m2eclipse-webby/0.2.2/N/0.2.2.201410021251/

https://repository.takari.io/content/sites/m2e.extras/m2eclipse-webby/0.2.2/N/0.2.2.201410021251/ is a better URL. although won't happen any time soon, I plan to shutdown plain-text 8081 listener eventually.
