I'm having trouble getting SpringSource Tool Suite to compile and deploy a Java class located in a Grails project's src/java directory when I run the application from within STS. This is particularly odd given that I have a ServletFilter in this same location (albeit a different package) that gets compiled just fine, so I decided to dig into things a bit and figure out where STS deploys projects when you do grails run-app. This way I could at least see whether or not the class was getting deployed and if my class not found exceptions were related to some other issue.Turns out if you watch the console as the app launches you get a big clue. Well, the answer actually. I'm on Ubuntu so in my case, my project was deployed to /home/mwoodward/.grails/1.2.1/projects/PROJECT_NAME/resources, so I poked around in there to discover that it even creates the package for my Java class but alas, there's no compiled class in the package. At least I confirmed I'm not losing my mind. Now to solve the mystery of why STS isn't compiling and deploying that class.
