      The second thing I did wes to download the Skeleton Plugin.

      from here :


      without changing anything in the plugin I try to build it using mvn install

      but I am receving an error :


      C:\skeleton-plugin>mvn install

      I feel like it doesn't matter what I'm do I can't get it to create simple plugin.

          it is sad that you had such a bad experience when starting to write a plugin. The blog post you mention in part 3 is relatively old and we have changed some maven pom things where it looks like you are stumbling upon. In Option 1 you clearly run into a bug - I will look into that as soon as I can.


          Currently the best bet is perhaps to take a plugin like hibernate, copy everything over into a parallel subtree below modules/plugins/ and rename hibernate all over by the name of your plugin.


          Thanks for pointing that out and I will get back to you when the issue with the plugin generator is solved - especially as the input you have pasted in looks pretty valid. Just curious: what jdk are you using?


          Sorry for the inconvenience

            Hi Heiko,

            Thank's for your answer, I will try to use hibernate in order to generate my own plugin.

            my system info:

            windows 7 64 bit.

            java -version :

            java version "1.6.0_22"

            Java(TM) SE Runtime Environment (build 1.6.0_22-b04)

            Java HotSpot(TM) 64-Bit Server VM (build 17.1-b03, mixed mode)

            If there any other information you need from me please let me know.
