I'm really close to getting it working both in the CLI and in Eclipse,
but I have an issue which I don't know how to fix. Even though the
project only has a '/src' folder configured:

- when building in Eclipse, project.getCompileSourceRoots() returns
['src/main/java'],
- when building using the CLI, project .getCompileSourceRoots() return
['/src/main/java','/src']

The build work in the CLI, with warnings, but it fails to generate SCR
descriptors in the IDE. Any ideas on why that happens? Using tycho
0.18.1 .

Thanks,

Robert
