Resolution: Rejected
> generating with generic hbmtemplate and maven 1.1
> --------------------------------------------------

> Key: HBX-1059
> URL: http://opensource.atlassian.com/projects/hibernate/browse/HBX-1059
> Project: Hibernate Tools
> Issue Type: Improvement
> Components: datagen
> Affects Versions: 3.2.beta11
> Environment: hibernate 3.2.6, maven 1.1, ant 1.6.5
> Reporter: Nicolas Andres
> Priority: Blocker

> There is a problem referencing the freemarker templates when using maven 1.1. The hibernate-tools.jar and freemarker.jar have to be referenced in the POM file with the tag <classloader>root</classloader> otherwise the classes are not found when executing the hbmtemplate task. The defined classpath (<ant:classpath>....) will be loaded by a different classloader (AntClassLoader) which has the root classloader as parent classloader. So, I do not see a way to reference the ftl templates in the ant:classpath.
> Unfortunately, the freemarker templates can only be referenced relative to the classpath and not as absolute file names. Because maven does not support to load resources on the root classpath (unlike jars) it is not possible to use hibernate tools as shown below.
