scala 2.12.3 is on my path

$ which scala
/c/Program Files (x86)/scala/bin/scala

When I run

$ sctags -R ./

from inside a scala project, I get

$ sctags -R ./
Error: Could not find or load main class .

Made a pull request to change Line: to line: here #3

I just cloned the repository and built it following your instructions. When I run sctags on the sctags project I get an exception:

Command:

sctags -f TAGS -R src/main/scala

Backtrace:

How do I fix this?

Thanks

Thanks for the great project!

I'm attempting to use GNU global to tag a Scala project. Global has the ability to use plugins, one of which is exuberant-ctags to perform the tagging. I can point it at sctags, but I get some errors around flags that sctags doesn't support:

I don't know how much work this would be, but it would be nice to either fake out these flags or support them fully so that things that expect exuberant-ctags functionality, work.
