Exclude certain files patterns in a pre-recieve hook while calling commitService.streamDiff

[kairazeh]

Hi ,

I am trying to write a pre-recieve (preUpate) hook to get the Diff content for a commit and scan for the specific  strings  from the Diff using commitService.

commitService.streamDiff(new DiffRequest.Builder(repo, commitId).build(), new DiffContentCallback() {
        //implement methods that are called as the diff is streamed.
        //grep specific string pattern
         
    }); 

However , I do not wish to scan on the entire Diff results  from StreamDiff and want to exclude certain file with specific extentions (such as .json files) 

Can you help me with some examples to achieve this

Thanks
