Maven errors question [message #1060731]

Hello folks

I was wondering if I could get some help with my maven setup?
I have been using this example as my base for building my maven setup, but since I only need the jar file and not a compilation I have modded the mydsl pom file.

When I extract it in eclipse as runnable jar with the option "Package required libraries into generated Jar" everything works fine, but when I build and run the jar with maven I get the following errors:

----------------------ERROR--------------------------------------
log4j:WARN No appenders could be found for logger (org.eclipse.xtext.parser.antlr.AbstractInternalAntlrParser).
log4j:WARN Please initialize the log4j system properly.

I don't really know what files may help you I thought atleast I might post the pom for this file and the mydsl (which is iidsl for me) projects.

IiDSL pom

Hmm... might as well ask, but since I only want to compile a jar file from my main class which turns my dsl file into an xml file by using the generator, do I need to build all the projects they have in the xtext-maven-example or can I simplify it?

Thanks for any help

Hi,

I should probably have mentioned it. But I did stumble over it, fell quite hard and no wiser when I got up Smile

I tried to remove the log4j and repackage them in the standalone but it didn't seem to help.
I guess I missed something so will look into it again.

Well, sorry for taking your time if the answer already was here Smile

Hi,

meh! Sorry for taking up your time. Seems I forgot to fix in the repackage.xml file.
Now I only have the log4j warning but... since it compiles I will take that when I have more time Smile

Sorry again, its like when you ask the teacher about something and just as you ask you find the answer.
Well, at least people here have good patience with me Very Happy

Have a good day
