FW: Maven2 jar classpath

["Ilyevsky, Leonid (Equity Trading)" <Le...@ml.com>]

Brett,

I tried using <addClasspath> tag again few days ago. Still does not work
for the default "compile" scope.
I assume I have to wait for the next alpha release to get your fix. For
the time being I am using <manifestFile> feature.

However, even if <addClasspath> works, the way it is now is not very
useful (I mentioned this problem in one of my previous postings).
It will include dependent jar file names without any directory prefix,
like if they are sitting in the same directory. But they are not in the
same directory!
For example, my program 

        ...repository/mygroup/myprog/1.0/myprog-1.0.jar 

depends on 

 
...repository/commons-collections/commons-collections/3.1/commons-collec
tions-3.1.jar

The classpath generated by maven will have
"commons-collections-3.1.jar", but it should have 
"../../../commons-collections/commons-collections/3.1/commons-collection
s-3.1.jar".

Then I really can run my jar file out of repository.

Any thoughts?

Thanks Brett. I will try it Monday (it is time now to go home).
One more related question. The classpath I am getting this way will list
just the names of the jar files (no path).
So, it will work if my program's jar file and all dependencies are all
in one directory.
I guess, this is reasonable, to have it in one directory in runtime
environment.
The question is, can maven2 automatically put my program jar and all
dependencies in one directory? Or something equivalent to this, so after
doing "m2 deploy" I can run it with "java -jar myprog.jar".

I'm pretty sure they do.

Ok, there was a bug in the "addClasspath" handling. Fixed.

Correct.

That's not very portable if you want to move the JAR around, though.

I think that the Classpath: manifest entry is not very useful :)

You might like to try the "jar-with-dependencies" assembly that simply
folds all of the JARs into one. Or zip all the dependencies up in one
directory. We are looking into more sophisticated ways of building
distributables along these lines.

Cheers,
Brett
