Every time I modify my code I have to run grails clean before running grails run-app. If I don't, I get messages like this:

This is really odd, because it seems Grails cannot load the Oracle database driver... but it loads fine if I run
grails clean
grails run-app
This app I'm working on was upgraded today from Grails 2.2.4. The upgrade was seemless (until this). All I had to do was change the hibernate and tomcat versions then run grails upgrade; grails clean
Any ideas how I can get it so I can modify the code and just restart using grails run-app or better... get the reload functionality to work, so when I make code modifications it automatically compiles the file I just saved (this worked great in Grails 2.2.4).
