I could see in your action logs that you're using Maven 3.10, which means you're probably running into the issues described at https://lists.apache.org/thread.html/6mn9yh5mj9bcfsbb4bkoxw2m5vybyjyk.

If you cannot wait for a newer version of the plugin, you probably need to (temporarily) change your job to use a different Maven. Unfortunately that cannot be done using the actions/setup-java action, see https://github.com/actions/setup-java/issues/457. There is a comment that suggest using https://github.com/s4u/setup-maven-action instead. Alternatively, use a Maven wrapper added to your repository.

this error seems to be from `central-publishing-maven-plugin`
I would check
  - if most recent version of plugin is used
  - manually unpack the archive being uploaded to
https://central.sonatype.com and check the contents

I am trying to do a deploy to central portal from a github actions

The workflow fails when trying to deploy the BOM (which has been
detached from the maven pom parent by flatten-maven-plugin):

The error message is:

common:
  - Bundle has content that does NOT have a .pom file:

no/priv/bang/jdbc/jdbc.sqldumper, no/priv/bang/jdbc/jdbc.datasourceproxy

Why are the other projects mentioned when the failure is in jdbc-bom?
(And I am quite sure they all have pom files!)

I note that the error message is similar to this error, would downgrade
mvn work for me as well?
  https://lists.apache.org/thread.html/1trdtdct2glycrzqo6xhbryns5o5pxno

Are there any other obvious things I could try?

I tried adding "-e -X" to the mvn command to get more debug info, but
the result was mostly noise:

Thanks!
