Dear,

While hibernate and spring project has moved to gradle. Hibernate tools do not provide a plugins to be used with gradle.
I develop a little plugin that do this job: https://github.com/institut-de-genomique/hibernatetools-gradle-plugin

It could to be interesting to add to this plugins or a new one some feature as custome template generation.

I am not an expert of ant and his hibernatetools configuration for this tasks.

You are welcome to improve the plugins, fork and merge to the hibernatetools project.

I never found how to to use a custom template: https://forum.hibernate.org/viewtopic.php?f=6&t=1039360

Regards
