Can I use JDT outside Eclipse to manipulate Java code?
JDT Core has no dependency on UI side, however it requires a runtime-workbench. Hence you can use it in an Eclipse headless application or include all the dependent jar files in the class path of your application. (You will have to use ASTParser.setSource() and ASTParser.setEnvironment() to be able to parse non Eclipse Java projects.)
