This action is heavily inspired by robotology/gh-action-nigthly-merge.

Automatically merge one branch into another.

If the merge is not necessary, the action will do nothing. If the merge fails due to conflicts, the action will fail, and the repository maintainer should perform the merge manually.

To enable the action simply create the .github/workflows/upmerge.yml file with the following content:

name: 'Up merge'

on:
  push:

jobs:
  nightly-merge:

    runs-on: ubuntu-latest

    steps:
    - name: Checkout
      uses: actions/checkout@v2

    - name: Up Merge
      uses: bambamboole/gha-upmerge@master
      with:
        stable_branch: 'master'
        development_branch: 'develop'
      env:
        GITHUB_TOKEN: ${{ secrets.GITHUB_TOKEN }}

The name of the from branch (default master).

The name of the to branch (default develop).

User name for git commits (default GitHub Upmerge Action).

User email for git commits (default [email protected]).

Environment variable containing the token to use for push (default GITHUB_TOKEN). Useful for pushing on protected branches. Using a secret to store this variable value is strongly recommended, since this value will be printed in the logs. The GITHUB_TOKEN is still used for API calls, therefore both token should be available.

      with:
        push_token: 'FOO_TOKEN'
      env:
        GITHUB_TOKEN: ${{ secrets.GITHUB_TOKEN }}
        FOO_TOKEN: ${{ secrets.FOO_TOKEN }}
