How to find a particular text in entire codebase - Groovy Jenkins

Question

Within a Jenkins-Groovy pipelines I want to do the following:

1. Clone a particular GitLab based Code repo.
2. Then within this repo I want to find out all the files where there is a particular string. Example: "find_me"
3. Once found I want to change all these files from find_me to found_me.
4. Then commit these changes to the GitLab repo.

Step 4 above maybe I can find out myself, but I am struggling on how to do the 2nd and 3rd steps mentioned above.

Can anyone please suggest what can be the best way to do this?

Answer 1

1. Pipeline: SCM Step
2. findFiles: Find files in the workspace
3. readFile: Read file from workspace, writeFile: Write file to workspace, prependToFile: Create a file (if not already exist) in the workspace, and prepend given content to that file.
4. You can't commit to a GitLab repo directly from within Jenkins. You add/commit/merge locally, then you push. See, for instance: Is it possible to Git merge / push using Jenkins pipeline.
