CT4E is to the Maven plugin as m2eclipse is for maven: it uses Eclipse for what Eclipse does best, and Maven for what Maven does best. CT4E leverages the Eclipse incremental compiler and WTP to enable immediate run/debug and class replacement at debug-time without having to restart the world. And it also supports deployment from within Eclipse.
