How to prevent the extension from checking files in bin folder?

[felipecrs]

I use Gradle in my project, and because of that, gradle generates some build output in a folder called bin. The extension wrongly sees my source files as being defined there as well:

Invalid duplicate class definition of class com.company.internal.river.jenkinssharedlibrary.MBReportJobStart : The sources /local/home/user/repos/jenkins-shared-library/src/com/company/internal/river/jenkinssharedlibrary/MBReportJobStart.groovy and /local/home/user/repos/jenkins-shared-library/bin/main/com/company/internal/river/jenkinssharedlibrary/MBReportJobStart.groovy each contain a class with the name com.company.internal.river.jenkinssharedlibrary.MBReportJobStart.
 @ line 11, column 1.

Hello @felipecrs,

As you can see my holiday break was very long 😎 but I'm back now.

This is a good ask and a problem I have also faced. I'm not sure yet if the fix is needed in the client or the server. Will take a look soon.

Thanks

Man, it's me who says thanks for the awesome initiative!

Still working on this =/

Probably going to have to fix it server side and not client side.

I'm facing this same issue with the bin folder being searched. Makes it unusable, unfortunately.

I also hit this - it seems to be the extension "Language Support for Java(TM) by RedHat" (redhat.java) which is creating these copies in bin/, see redhat-developer/vscode-java#634 (comment)

Until that is fixed, to avoid Groovy-Guru from flagging everything as a duplicate I added bin/** to the 'Files exclude' setting at the workspace scope, which is equivalent to adding the following in <workspace>/.vscode/settings.json

{
    "files.exclude": {
        "bin/**": true
    }
}

I am having similar issue with duplicates in .svn folder (yes, our company still uses it). I have .svn folder excluded globally and also locally via solution suggested by @sparrowt, but I am still getting this 'Invalid duplicate class definition' warnings. Any more suggestions how to get around that? I am wondering why would the extension ignore global vscode setting for exclude locations in the first place (.git, .svn, etc folders).
