Today the big problem with tern.java is when you have a lot of JS
files in
your project (with bower tool you can have a lot of JS files).
If you configure correctly your tern script path
https://github.com/angelozerr/tern.java/wiki/Tern-Script-Path you can set
the folder which contains JS you need to parse with tern.
BUT since 0.6.0, tern script path is configured by using JSDT Install Path,
and it can be a problem, because :
* in 0.6.0, the JSDT Install Path -> Tern script path was not very
managed. Problems comes from with lib configuration. In this case, project
folder is used.
I have fixed that in 0.7.0
* JSDT Install Path -> Tern script path must be improved again like
managing exclude script path
