Hi,
I'm not sure why I've been doing it, but anyhow I'd decided to do it
and it eventually took me longer than I'd anticipated. As you might've
guessed, I couldn't sort it out myself.
The problem is with how the transitive dependency in M2 works *and*
how I understand it. After I'd built OpenEJB3, I took a look at m2
local repository and noticed a couple of older libraries that should
not have been there. We don't need them so why M2 downloads them?
Just an example - itests/openejb-itests-beans. It needs
geronimo-jms_1.1_spec 1.1, but somehow 1.0.1 is downloaded, too. What
I did was to specify the exclusion in the main pom.xml:
<exclusion>
<groupId>org.apache.geronimo.specs</groupId>
<artifactId>geronimo-jms_1.1_spec</artifactId>
</exclusion>
as part of org.apache.openjpa:openjpa-persistence-jdbc. It ended up
with a failure because of missing JMS classes. I said, well, I need to
specify the dependency (the one I had excluded earlier) in the
openejb-itests-beans. And so did I.
<dependency>
<groupId>org.apache.geronimo.specs</groupId>
<artifactId>geronimo-jms_1.1_spec</artifactId>
</dependency>
Run mvn -N install in the main directory of OpenEJB3, and run mvn
clean install to see how it'd go. It failed. Why? It seems that the
parent exclusion was of greater importance to M2 and although I had
declared the deps in openejb-itests-beans, it didn't help, either.
So, I had to remove the exclusion and now M2 downloads two versions of
geronimo-jms_1.1_spec - 1.1 and 1.0.1. Why?

What's more annoying is that I tried to use some dependency display
tools, like mvn tools:show-dependencies -Dverbose=true, but it showed
noone needed the 1.0.1 version. Why?

I'm loosing my patience with it. I'd better go doing something easier.
Anyone willing to lend me a helping hand?
