Although a relatively lightweight IDE, it features surprisingly powerful indexing and code analysis capabilities, as well as useful tools, among which are make integration. While the tools it provides are not always as sophisticated as other IDEs (IntelliJ IDEA will likely come to mind as one such competitor), the simplicity of using it, as well as the reliability of this rugged IDE makes up greatly for the slightly less advanced tooling. Eclipse requires very little starting infrastructure in the workspace for all these features and indexing support as well, which makes it a good candidate for developing on the JDK.

Cross Compiling support is available, and in its entirety the change touches very little of the existing make system, barring its own Makefile within the ide subdirectory.
