Incorrectly excluded directory

A problem I had was that some references remained unresolved by the language server although they were correct.
The problem turned out to be that they were under a target directory, which is excluded by the language server, as seen in the following snippet.

kotlin-language-server/shared/src/main/kotlin/org/javacs/kt/SourceExclusions.kt

Line 13 in bc53099

    
           private val excludedPatterns = listOf(".*", "bazel-*", "bin", "build", "node_modules", "target").map { FileSystems.getDefault().getPathMatcher("glob:$it") }

Solution

I think ideally, the language server should do something more sensible than using the hardcoded exclusion rules and allow customization of that behaviour via options.

But for now, a workaround is to symlink the incorrectly excluded directories to a non-excluded name.
E.g. in my case I used ln -s target trgt.

I agree, the current solution is not optimal and we should either query the build system (ideal) or at least the .gitignore as a heuristic on which files to exclude. Letting the user configure these exclusions manually could be convenient too. There's a todo comment a few lines above that addresses this:

kotlin-language-server/shared/src/main/kotlin/org/javacs/kt/SourceExclusions.kt
