Maven dependencies still not working properly.

[adrian.brock]

In the common project there is a jbossxb-builder project
http://anonsvn.jboss.org/repos/common/jbossxb-builder/trunk/

This specifies EXPLICITLY a dependency on jbossxb-2.0-snapshot,
but it is actually picking up jbossxb-2.0.0CR3 via dependency on jboss-container

[DEBUG] Output directory: /home/ejort/common/jbossxb-builder/target/classes
[DEBUG] Classpath:
[DEBUG] /home/ejort/common/jbossxb-builder/target/classes
[DEBUG] /home/ejort/.m2/repository/jboss/jboss-vfs/2.0.4.snapshot/jboss-vfs-2.0.4.snapshot.jar

WRONG

[DEBUG] /home/ejort/.m2/repository/jboss/jbossxb/2.0.0.CR3/jbossxb-2.0.0.CR3.jar
[DEBUG] /home/ejort/.m2/repository/jboss/jboss-common-logging-spi/2.0.4.GA/jboss-common-logging-spi-2.0.4.GA.jar

[DEBUG] /home/ejort/.m2/repository/apache-xerces/xml-apis/2.7.1/xml-apis-2.7.1.jar
[DEBUG] /home/ejort/.m2/repository/apache-slide/webdavlib/2.0/webdavlib-2.0.jar

CORRECT BUT NOT USED

[DEBUG] /home/ejort/.m2/repository/org/jboss/jbossxb/2.0.0-SNAPSHOT/jbossxb-2.0.0-SNAPSHOT.jar

This is causing it to fail to compile.

How do we fix this so it is not stupid?

For some reason, transitive deps show up in the classpath before direct dependencies, so you get issues like this. It's something I will eventually try to fix in maven, because I think direct deps should come first.

For now, you can exclude the transitive dep on jbossxb by adding this to the container dependency.

 <dependency>
 <groupId>org.jboss.microcontainer</groupId>
 <artifactId>jboss-container</artifactId>
 <version>2.0.0-SNAPSHOT</version>
 <scope>compile</scope>
 <exclusions>
 <exclusion>
 <groupId>jboss</groupId>
 <artifactId>jbossxb</artifactId>
 </exclusion>
 </exclusions>
 </dependency>

Thanks that worked. I put a FIXME in the pom.

[adrian.brock]

This doesn't appear to be a generic fix.
e.g. see this related problem
http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4079196#4079196
where Ales and I are getting different build dependencies.

I changed the container pom to exclude it's transitive dependency (through jbossxb) on jboss-common-core. This seems to give the correct dependencies at compile time.

To find this, I used "mvn project-info-reports:dependencies" which creates an html page that shows the dependency tree.

I also used "mvn dependency:analyze" which currently gives me these warnings:

I'm going to update the dependencies in container to clean up these warnings.
