Hi Jacob,
you are talking about the Android sources? (For reference: JavaME related stuff is documented
here.)
(Please don't be intimidated if this explanation has too much information for you, it's just so that I can point anyone here who is asking about this later...

)
I'm using
Eclipse Galileo with
ADT Plugin. Then building can be done by right-clicking on the project, choosing
Android Tools, then
Export (Un)Signed Application Package...
My workspace looks as following: There are two projects, one is a SVN-Java-Project called DictionaryForMIDs (checkout of trunk/DictionaryForMIDs) and a SVN-Android-Project called DictionaryForMIDs_Android (checkout of trunk/Android). I added the project DictionaryForMIDs to the Java Build Path of DictionaryForMIDs_Android (
Project ->
Properties ->
Java Build Path ->
Projects ->
Add) to make sure the compiler finds all the necessary code.
SVN-Java-Project stands for: Install Subclipse Plugin, then choose create new project from SVN (
File ->
New Project... ->
SVN ->
Checkout Projects from SVN and choose check out as Java project when asked...)
Hope that helps - and please tell me if anything is missing / unclear.
Achim
