> To do something good for the environment it would be awesome to change this.
> There are the following options:
> 1. convince every individual project to change their build scripts and add {{-B}}
> 2. convince every CI provider to add {{-B}} to {{MAVEN_OPTS}}
> 3. build some magic into maven that will notice if it is running inside CI or generally headless and then enable batch mode automatically.
> My few cents on these approaches:
> 1. never gonna work. New projects show up faster than you can fix existing ones.
> 2. possible but tricky
> 3. maybe somewhat ugly from the maven PoV but the most effective one (at least after a longer time when all CI vendors have updated to such maven version).
> Input for 3.:
> * Travis: {{CI=true}} - see https://docs.travis-ci.com/user/environment-variables/
> * CircleCI: {{CI=true}} - see https://circleci.com/docs/2.0/env-vars/#built-in-environment-variables
> * GHA: {{CI=true}} - see https://docs.github.com/en/actions/learn-github-actions/environment-variables#default-environment-variables
> * Jenkins: {{CI=true}} - see https://issues.jenkins.io/browse/JENKINS-36707
> So actually 3. would not be hard to do but could save a lot of waste (many many terra-bytes word-wirde again causing lots of bandwith and lots of time for humans to read logs and find the interesting spots again consuming more energy).
> Could you please think about it?
