Describe the use-case for this feature

In definition ofOutputPathItem, the spec has kind forFile andDirectory. But in some cases, these two might not be enough.

For example. In Gradle, the source set can have different output paths for class files and resource files:

The spec has two dedicated requests for sources and resources. What's the recommended way to differentiate the output of them?

What do you propose

?kind=sources or?kind=resources

I've checked to make sure there isn't already a way to support this in the current protocol

• I've checked the existing protocol and there isn't a way to do this currently
