OpenJPA-149 changes are not IDE friendly
----------------------------------------
Key: OPENJPA-584
URL: https://issues.apache.org/jira/browse/OPENJPA-584
Project: OpenJPA
Issue Type: Improvement
Components: build / infrastructure
Affects Versions: 1.2.0
Reporter: Michael Dick
Assignee: Michael Dick
Priority: Minor
Fix For: 1.2.0
The changes made for OPENJPA-149 included committing compiled classes into
openjpa-kernel/src/main/resources. We're using these compiled classes (mainly
interfaces) to avoid reflection in the WASRegistryManagedRuntime class. The
classes aren't shipped with OpenJPA and are expected to be present only in a
WebSphere environment.
The maven build process copies these class files into the target directory
before compiling the source code. Unfortunately this approach causes problems
with many IDEs (I tested Eclipse & IDEA).
The ideal solution is to pick up the UOW interfaces from a central maven
repository, but currently they're unavailable and the license agreement with
IBM prevents us from distributing the jar file ourselves - it can't be made
available outside of our build environment.
To resolve the problem I created an internal repository which can be checked in
to SVN. The repository is local to the openjpa-kernel module but could be moved
elsewhere in the build tree. Openjpa-kernel/pom.xml has been modified to use
this repository and pick up the websphere jar as a "provided" dependency.
Provided scope dependencies are not transitive and will not affect downstream
projects.
In addition the jar file and the internal repository will be included in the
source archive, but will not be present in the binary archive.
Using the internal repository should resolve many of the problems with IDEs
(although I've only tested the fix with Eclipse). Some manual configuration may
still be needed but this approach seems to work better than what we had before.
