Lint broken with latest version on our CI

Expected Behavior

Lint running well

Current Behavior

Lint breaks

Failure Information (for bugs)

After upgrading to v8.7.0 from v8.6.0 lint breaks with the following error message on our CI:

Error: Command failed: git merge-base master HEAD
fatal: Not a valid object name master

command:

$ npm run lint
> nx workspace-lint && nx affected:lint --parallel --all --maxParallel 4

Runs well locally. Runs well on CI with v8.6.0.

Steps to Reproduce

nx affected:lint --parallel --all --maxParallel 4

Context

• nx v8.7.0
• gitlab CI
• works well with nx v8.6.0

When using Merge Requests on GitLab CI git merge-base master HEAD won’t work on the runners. You’ll need to run git fetch origin before anything else.

I can confirm that git fetch origin helps on Gitlab CI.

.gitlab-ci.yml:

image: node:lts

before_script:
  - yarn install
  - git fetch origin

stages:
  - lint

Linters:
  stage: lint
  script:
    - yarn lint

package.json:

"scripts": {
   "lint": "nx affected --target=lint --base=remotes/origin/master --parallel"
}
