Well, it is easy, but it is hard ;-)

There are also two stages to the implementation:

Stage 1 - Install from src
--------------------------

The easy part is:

add a new condition to the plugin download code that detects when the 
src files are available and does a 'local-deploy' in preference to 
downloading the unversioned plugins (versioned plugins should always be 
downloaded). This is all done in main/targets/plugins.xml

The hard part is:

the versioned download stuff in main/targets/plugins.xml is in need of 
refactoring, it is quite complex right now because of all the 
conditional behaviour, Ant is not a programming language and it shows in 
that file. I have created an issue to convert it to an Ant task.

Stage 2 - Use in-place
----------------------

Change the plugin mounting code to mount the plugins from the src directory.

---

Both stages can be done without the refactoring, it shouldn't add too 
much additional complexity since the extra condition tests would be 
added to existing ones. However, I don't want us to loose sight of the 
refactoring that is needed.

Speaking personally, I don't have the time to do this right now (should 
do after ApacheCon), however, it is something that is very important. If 
someone wants to tackle it I will be sure to help out with any questions 
they have.
