> With Maven 3.9.0, `maven.config` requires each flag on a separate line
> ----------------------------------------------------------------------
>
> Key: MNG-7684
> URL: https://issues.apache.org/jira/browse/MNG-7684
> Project: Maven
> Issue Type: Bug
> Affects Versions: 3.9.0
> Environment: Maven 3.9.0
> Ubuntu 20.04.5 LTS
> Bash shell
> Reporter: Stephan Schroevers
> Priority: Major
>
> Prior to Maven 3.9.0, the {{.mvn/maven.config}} file supported multiple flags
> on the same line. As of Maven 3.9.0 the flags must be on separate lines. I
> _assume_ that this is an unintentional regression.
> To reproduce, run:
> {code:sh}
> git clone [email protected]:PicnicSupermarket/error-prone-support.git
> cd error-prone-support
> git checkout d1f513373fffe21fa463a9d6978cdfa8940e1ce4
> mvn -version
> {code}
> With Maven 3.8.7 the {{mvn -version}} command completes successfully. With
> Maven 3.9.0 it fails with:
> {noformat}
> Unable to parse maven.config file options: Unrecognized option: --batch-mode
> --errors --strict-checksums
> {noformat}
