Building in Eclipse
Hi
Does anyone have any experience (preferably successful) of building
openjpa-kernel in Eclipse?
I've found that checking out each sub-project from trunk usually works
fine when building against a released version (as then I can download
the pre-compiled openjpa-kernel from the maven repo) but this doesn't
work so well when working with trunk.
Working from the command line is fine but a bit limited in Windows -
especially when trying to patch the source!
My specific issue is that Eclipse complains of compile errors in the
(src/main/java/)org.apache.openjpa.kernel.jpql package as these files
depend on the jjtree sources. If I add target/generated-sources/javacc
to the build path I get a name clash with the SimpleNode class in both
the src/main/java and target/generated-sources/javacc folders. I also
tried adding the target/generated-sources/jjtree folder in place of the
target/generated-sources/javacc folder but this didn't work either.
Sorry if I am being thick with this. I need my IDE!! ;)

Hi Alan,
I use the maven eclipse plugin to generate eclipse .project and .classpath
files. I have to do a little massaging afterwards but it does 90% of the
work for me. You'll still have to add the generated-sources stuff though.
I usually add target/generated-sources/javacc to the build path and remove
the directory with the duplicate SimpleNode. FWIW I've attached the
.classpath file that I use with trunk. It relies on the M2_REPO classpath
variable being defined and pointing to your local Maven repository so you
might have some massaging to do too.
Hope this helps,
-mike

Thanks for pointing this out. I've been adding the variable manually for a
long time. The eclipse plugin should do it for you if you run :
$ mvn eclipse:configur-workspace -Dworkspace=${path to your eclipse
workspace}
I haven't tested it yet though, but I can give it a try tonight and add to
the wiki.

Thanks again. For trunk you should only need javacc (at least that works for
me). For older branches I believe you need them both.
I didnt understand why they were added to exclusion fileset.. is there any

No harm at all. Includes + excludes + eclipse:eclipse are a bit ticklish.
Glad you got it up and running.

RE: Building in Eclipse
Posted by "srini.krish" <sr...@gmail.com>.
Hi,
I tried setting up with eclipse and was successful too.. :)
I exactly followed this link given by Michael
[1]
http://cwiki.apache.org/confluence/display/openjpa/Building#Building-Eclipse
But there were a couple of points that were not mentioned..
1. M2_REPO - variable need to be created in eclipse which points to the
local repository.
2. Under OpenJPA-kernal, the jjtree and javacc folders were added to
exclusion filters.. Instead I added them to my source folders..
I didnt understand why they were added to exclusion fileset.. is there any
harm in having them under source folder?
Thanks and Regards,
-Srini

Subject: Re: Building in Eclipse
I think this is a variation on the "one big project" approach that some
people seem to like. I prefer to build each module as a separate compilable
unit (ie the way maven does). The benefit is that when I break access rules
(ie try to reference something from openjpa-jdbc in openjpa-kernel) my
eclipse build failes before I do a real maven build..
It's all personal preference though and YMMV.. IDEA and NetBeans have built
in maven support that (I'm told) works pretty nice. I can't give up
Eclipse's incremental compiles though.
FWIW the steps for the multiple module approach are on our wiki at [1]. If
you're willing to start from scratch that might be a good place to do.
Donald's done a great job of updating that section of the wiki to keep it up
to date (thanks Donald).

Re: Building in Eclipse
Posted by Pinaki Poddar <pp...@apache.org>.
Hi Alan,
I build/debug OpenJPA in Eclipse in a somewhat non-kosher way. The
complexity arises because OpenJPA is a multi-module project and requires
some javaCC generated source code.
So I am not prescribing the steps but purely describing what works for me.
1. checkout openjpa source code to say a directory X. You can check the
project out from Eclipse itself too. Then ignore Step 3.
2. compile with maven -- this will create javacc generated source code
which is required for next steps.
Also it will fetch the dependent libraries in local maven repository.
3. create an Eclipse project with root directory X
4. add a whole bunch of 'source folders' to the Eclipse project (see
attached .classpath and .project
files). The output for each of these 'source folders' are different and
should match maven target directory to keep maven and Eclipse build in
synch.
5. Define a bunch of 'User Libraries' and attach the corresponding jar
that Step 2 has placed in local maven repository.
Now the Eclipse project can be cleaned and built with 3 errors about
javaCC generated code. I still could not get rid of them -- but they seemed
to be harmless enough for me so far.
