Biggest wins first, each with the exact config fix.
Missing dependency cache · build
Set `cache: 'gradle'` on your `actions/setup-java` step, or add an `actions/cache@v4` step keyed on your build file.
- uses: actions/setup-java@v4
with:
distribution: 'temurin'
java-version: '21'
cache: 'gradle'No concurrency control · build
Add a `concurrency:` block keyed on branch to cancel superseded runs when devs push twice quickly.
concurrency:
group: ${{ github.workflow }}-${{ github.ref }}
cancel-in-progress: trueAlso found: 3 more config fixes with negligible recoverable minutes: timeouts, retention, path filters
No job timeout · build
No job sets `timeout-minutes`, so a hung step can run to GitHub's 6-hour default. Add `timeout-minutes` to each job.
jobs:
build:
runs-on: ubuntu-latest
timeout-minutes: 15Artifacts at default retention · build
`upload-artifact` has no `retention-days`, so artifacts keep up to 90 days (storage cost). Set e.g. `retention-days: 7`.
- uses: actions/upload-artifact@v4
with:
name: build
path: dist/
retention-days: 7No path filters on triggers · build
Runs on every push/PR with no `paths:` filter, so docs-only changes still trigger full CI. Add a `paths:` filter if that's common.

paths:
- 'src/**'
- 'package.json'Copy every fix as one block (5 snippets, annotated per workflow)
