Thank you, but these sources seem to not match with the version I search.
What i am searching are the hibernate-tools-3.2.0.ga sources from the org/hibernate group ID.
I thought, it was the same jar, but with your answer I am guessing it isn't.
Thus, I will ask my question on hibernate forum as well.
Thank you very much for your help.
I contacted Max Rydahl Andersen, a big contributor of this plugin and thus I managed to find what I was looking for.
There may be other people searching for old version of org/hibernate/hibernate-tools
Thus, here is the link to the svn repo which can be useful to get older versions :
(It may save some time to know that the version of hibernate-tools can be found in the "build.xml" file or in the Branch_3_2/src/java/org/hibernate/tool/Version.java
