Fabric8 MVN Plugin 3.5.41: Allow @sha256 digest for tags in FROM

Hello there!

Today I ran into an error in Jenkins, using the fabric8 maven plugin, that seems to exist for quite some time. It got already reported in docker-maven-plugin Issue #541 but it looks like it never got fixed (Issue still open).

As the headline states the fabric8 maven plugin in version 3.5.41 is not able to process @sha256 digests.

In the docker-maven-plugin the responsible class seems to be ImageName.java. More likely the regex Patterns at the end of the file.

Does a solution to this problem already exist or exist plans to eliminate the problem?

If so, please give notice, that would be much appreciated

Cheers, Marcus

We just need to update to docker-maven-plugin 0.29.0 in order to fix this issue.

@mmkonrad : ah, apologies for the inconvenience caused. I missed this somehow 😦 . Will try to look into it as soon as I get time
