When used, this parameter will display a field at build-time so that the user
is able to select a Subversion tag from which to create the working copy for
this project.
Once the two fields Name and Repository URL
are set, you must (1) ensure the job uses Subversion and (2)
set the Repository URL field of Subversion
by concatenating the two fields of this parameter. For instance, if
Name is set to SVN_TAG
and Repository URL
is set to https://hudson.dev.java.net/svn/hudson/tags
,
then Subversion's Repository URL must be set
to https://hudson.dev.java.net/svn/hudson/tags/$SVN_TAG
.
