Re: [m2eclipse-user] m2eclipse readme.txt

[Mark Proctor]

I'm now using the latest svn url for tycho, not the m2eclipse one. I now manage to get the syncrhonize pom to output a list of dependencies, but I still need to manually add the swt stuff and also the dependencies that aren't osgi bundles. I also forgot to set the packaging to <packaging>osgi-bundle</packaging>. So it now gets further when building the drools-ide project, i.e. I don't get unresolved issues when compiling, but I do now get a null pointer. ...

What problems did you have ? Tom   I'm currently investigating maven-pst, but for some reason it keeps on insisting on 3.1.0 version dependencies for eclipse when only 3.2.0 and 3.2.1 are the only ones available on the ibiblio site, any ideas?
