I had thought that would be sufficient for re-constructing a  
particular view from the repository. Is that not the case?

Well, I had been loathe to spawn commands as part of the build  
process. For example, what if someone is using Eclipse's built-in  
Subversion client, and so do not have a separate "svnversion" command  
on their machine? Should we just fail the build, or silently ignore?

Parsing the .svn/entries file seemed like it would be a simpler  
process. Unfortunately, there is another reason we may need to change  
this: the latest Subversion release (1.4) changes the format of this  
file from XML to some custom format, which also breaks our parsing.

The goal is the action that you take on the plugin, not the phase in  
which the action is performed. The "maven-antrun-plugin" only has a  
single goal: "run".

It is the "phase" element that needs to be changed. Try "compile" and  
see if that fixes it.
