I can build and run processing fine using ant, however I’m having issues getting eclipse to work correctly, there are tonnes of build path errors. Following the [build instructions](https://github.com/processing/processing4/blob/master/build/README.md), it mentions that:

> it’ll complain about the lack of `jogl-all-src.jar`

This is true, but it’s also complaining about not having a lot of other jar files, like ant.jar, jna.jar, jna-platform.jar, gluegen-rt.jar, etc.

It’s not obvious where to find these, I could probably track them down from the build.xml but there should be a better way.

Any help is appreciated 🙂

I’ve found that almost all of the jars are included in the project, eclipse just didn’t detect them (Or I did something wrong). It seems like the relative paths weren’t working, so I’ve just gone through and made them all absolute paths.

The exception is jai\_imageio.jar for processing4-tools-moviemaker, which doesn’t seem to be in the project like the others. Where it should be is just ffmpeg.exe, and MovieMaker.jar.
