FAQ

• Can I ignore files from merge?

  Yes. create a .gitpathspec file in your repo root and list file(s) that you want to ignore during merge. Separate each line using LF. You can use glob patterns to select multiple files.

  sample .gitpathsepc file given below. This file ignores merge for all markdown files in the repo, package.json in the root of the repo and ci_cd/jenkinsfile.

  **/*.md
  ci_cd/jenkinsfile
  package.json

• Can I specify merge strategy when there are merge conflicts?

  Yes. Add the file(s) to .gitattributes (in root of your repo) and specify one of the below strategies. Glob patterns are allowed

  • merge=ours choose current branch changes during conflict
  • merge=theirs choose incoming branch changes during conflict

  sample .gitattributes file contnet below

  **/CHANGELOG.md merge=ours
  **/package.json merge=theirs
  README.md merge=ours
  ci_cd/jenkinsfile merge=ours
