Subject Re: Running ANT task before pulling down dependencies

Golder rule of build scripts: If they are not broken, don't fix them

Now if you want to refactor your build scripts from ANT to Maven
(which IMHO is a good thing) here is what I would recommend:

1. Set up a Maven Repository Manager (I use nexus, but there are
others, e.g. artifactory)

2. Start by adding Maven ANT Tasks to your ANT builds scripts.

2.1 Add an <artifact:deploy> to deploy your artifacts to the Maven
Repository Manager.
2.2 New projects can use Maven.
2.3 Stop using the "big bag of jars" lib folder concept and pull down
the intra-project artifacts from the MRM in the ANT build scripts

3. Take the ANT projects one at a time and convert to Maven
projects... if you do this slowly, you can probably keep the ANT build
script working in parallel.

Once you have passed step 2.1 above, you are free to mavenize projects
at leasure
