For release jobs we like to use the list tags plugin as an build parameter.
As svn allows almost any directory structure, we have archieved the hot fixes of a branch into a subfolder like the following example;

branches/
branches/versionA
branches/versionB
branches/versionC
branches/hotfix/versionB_01
branches/hotfix/versionB_02
branches/hotfix/versionC_01

In our jenkins job we like to be able to build every versionB release.
To make this possible we had to extend the current listtagsparameter plugins with an extra option "extraListDirs" we use it like;

url: url://somehere/.../branches
extraListDirs: hotfix
tagsFilter: versionB.*

So the resulting dropdown contains;
versionB
hotfix/versionB_01
hotfix/versionB_02

I've created a small patch for this, if its done correctly is it possible to merge it ?
