Re: [2.x] Failing unit tests due to classPath issues in Eclipse PDE platform

[Raymond Feng <en...@gmail.com>]

Hi,

There is an inconsistency between the maven and OSGi dependencies. Maven 
supports transitive dependencies while OSGi doesn't. In this case, we have 
contribution-xml pulled in by maven as a (transitive) compile-time 
dependency. But there is no explicit Import-Package in the MANIFEST.MF that 
references any packages from contribution-xml OSGi bundle.

To avoid duplicate classpath entries, we generate the .classpath in such a 
way that the compile/provided dependencies are NOT list as entries in the 
.classpath and they will be automatically added by the PDE classpath 
container. You can find more details in the "PDE integration of tuscany 
modules" section on page [1].

One way to fix the problem is to add a "runtime" dependency for 
contribution-xml to "override" the transitive "compile" dependency.
