Michael Baessler commented on UIMA-681:
---------------------------------------

I tried to work with the Maven properties without success. As you know we have a Project structure with one parent POM and many child POMs. 
In defined some properties in the parent POM but I was not able to access them in the child POMs.

The other issue is that in each child POM I have to specify settings of the parent POM and also the version of the parent POM :-( . So this can't work with inherited variables. 

So what else can we do:
If we remove the <version> tags from the child POM it inherits automatically the version from the parent POM. So what does this mean. 
- We don't have to change the version number for the child POMs
- We still have to change the parent POM settings (version number) for each child POM
- All child POMs have dependencies to other UIMA artifacts with the current artifact version. This can be replaced with ${project.version}.
This approach works for all child POMs except the plugin projects since these have a different version style. Some of the referred UIMA artifacts can be handled with 
${parent.project.version} but the POMs still have an own version that must be updated manually.


Another approach would be to try to load a Maven property from an external source to all POMs. In that case we have external dependencies for the build. 
I haven't tried that way, so I'm also not sure if it works.
