Lars Bruun-Hansen commented on MWRAPPER-157:
--------------------------------------------
[~hazendaz]: Maybe executing with {{MVNW_VERBOSE=true}} will give you some clue
as to what is going on.
Like you, I'm also using Maven Wrapper to test out some Maven 4 stuff vis-a-vis
Maven 3.
I haven't seen any problems on Windows 11 nor Ubuntu.
I use {{only-script}} mode.
> Maven wrapper jar is no longer downloaded on windows 11

> Key: MWRAPPER-157
> URL: https://issues.apache.org/jira/browse/MWRAPPER-157
> Project: Maven Wrapper
> Issue Type: Bug
> Components: Maven Wrapper Scripts
> Affects Versions: 3.3.2
> Reporter: Jeremy Landis
> Priority: Major
>
> mvnw started failing about a year ago unless curl uses -k option to download
> maven wrapper jar.
> mvnw.cmd now is also failing to download maven wrapper jar.
>
> Neither are working on maven 4 post beta-4. Therefore, I'm stuck here
> [https://github.com/spotbugs/spotbugs-maven-plugin/actions/workflows/it-maven-4.0.0.yaml]
> on older copy. Issue started with beta-5.
>
> To try to see what was going on, I tried locally windows 11 which has both
> the issues mentioned. Further looking, it appears to me that mvnw.cmd is
> using long deprecated windows code to download and should be upgraded. For
> the bash side of things, using git bash latest, the fact I have to add -k
> seems to indicate there is some issue with security.
> In all cases, if I put the maven-wrapper.jar in place, the maven wrapper
> itself works fine.
>
> To reproduce, just take the GHA from spotbugs and update it then let that
> build on your fork. Watch it fail. It will fail to see maven being there.
> Then force a maven wrapper jar into place, watch it then work. That same
> thing then can be repeated locally.
>
> I have a commit for adding -k for mvnw and have had it for a long time but
> something else has to be going on there. For mvnw.cmd, I've yet to figure
> out how to rewrite so its using proper code. Fixing issues with using
> obsolete microsoft logic there would be helpful but likely will drop windows
> 2016 support but given gradle already did so, eclipse ide already did so, and
> others I'm sure also have, it probably is the right time to drop legacy
> support.
>
> So what I'm looking for here is some resolution as to why -k is required to
> download the maven wrapper via curl and to fix windows code to not use
> deprecated code. Further, I'd like to actually be on maven 4.0.0-rc-2 on
> various plugins since using it does actually work provided the maven wrapper
> actually works correctly.
>
> Alternative, I could just write on GHA a curl myself and download it since
> the tooling straight up fails. But its very unclear why maven 4 fails
> whereas any older version beta 4 or before works fine there. Using ubuntu on
> that end.
