Re: [jboss-dev] Dependencies, class in multiple jar files, JBAS-1796, JBAS-6444
Jesper and I were discussing this yesterday and we also think adding
in features of my Delver [http://www.thefreedictionary.com/delve] tool
would be useful.
This tool scans directories for jars and inspects the manifest. It's
primary function is to report on lib versions, and locations so you
can identify duplicate jar files, and version mismatch. This tool
was how we found 3 different hibernate versions in EAP, and duplicate
libs all over the place. These could fit nicely together and could
provide detailed overviews of distributions.
Future options include:
* ant tasks, and maven plugins for this.
* Enable scanning of war, ear, etc...
* trigger test failures based on various conditions
* maven dependency reporting
* etc...

Hi.
I was going over the dependencies for the JBJCA project and needed a
tool to
get an overview of dependencies between jar files, if a class is
located in
multiple jar files and an overview of what each jar file requires and
provides.
So I hacked something together; currently called Tattletale - based on
javassist.jar of course.
I have attached the report for the application server to the issue
https://jira.jboss.org/jira/browse/JBAS-1796
as it could provide some information about the separation of the jar
files.
If you take a look at the 'Dependencies' report
under "common-httpclient.jar" - you'll see
https://jira.jboss.org/jira/browse/JBAS-6444
just to give you an idea.
The index.html file will provide the starting point for the various
reports.
If you think this tool would be useful I'll commit the code
somewhere in
repository.
Feedback is of course welcomed, but remember it is very early beta ;)
Best regards,
Jesper
