After some googling, I found that my x86_64 Macbook Pro had a populated ~/.m2/repository, while on the Mini it was unpopulated.

I fixed this by copying org/argouml/ & contents to the Mini's repository; all went fine after that.

But, how should I have set it up?

Hi Simon, I think the issue comes from a missing parentpom directory. I've checkout the sources by using repo with:

mkdir argouml
cd argouml
repo init -u git@github.com:argouml-tigris-org/manifest.git
repo sync

and then

cd argouml
mvn package

Having said that, each time I have to compile ArgoUML, I need to remember and fight again all these steps...

I thought that the parentpom would be found at the sonatype site. Testing a little around this I get the feeling maven does not use the default sites to find the parent. I also found this discussion on stackoverflow that suggests this.

I have now attempted to fix this by explicitly adding the sonatype repo in the argouml-core pom. This will have to be updated when the parent pom changes to not being a snapshot anymore. It should then point to the released version of the parent pom instead.

Please comment on the fix here in GerritHub.

That takes care of the argouml project I think. If you think this is an OK solution, I will solve it in the same way in the other projects.

I renamed my ~/.m2, and got the same error as before.

[linustolke]

The change is not merged to master yet. Did you download it from gerrithub? git fetch https://github.com/argouml-tigris-org/argouml refs/changes/77/542277/1 && git checkout FETCH_HEAD

[simonjwright]

Thanks for that hint; now working very satisfactorily (I deleted ~/.m2, then built: massive downloading!)

And I should say, argouml/src/argouml-build/target/argouml-jar-with-dependencies.jar runs fine.

[linustolke]

OK. Great. Thanks. I will merge that change now and eventually start fixing the other projects.

This is now fixed for all repositories. I have learned some things about the maven configuration.
