For the last couple of runs Metro-Core-4.2.x had lots of regression which could not be reproduced locally

As you can see it uses a different version of jbossws-jboss42-resources.zip. Namely the one available in jbossws-jboss42/4.2.3.CR1

I reverted to jbossws-jboss42/4.2.1.GA for various reasons that are being discussed elsewhere.

The issue at hand is that

 <get src="${jboss.repository}/jboss/jbossws-jboss42/${jbossws-jboss42}/lib/jbossws-jboss42-resources.zip" dest="${thirdparty.dir}/jbossws-jboss42-resources.zip" usetimestamp="true" verbose="true"/>

uses the timestamp on the destination file and if newer does not replace the file.

We could of course usetimestamp="fasle", which would result in every thirdparty artifact being downloaded every time. Hence this would make the hudson runs realy slow.

I am trying a different approach, that would delete the thirdparty.dir whenever the version.properties changes
