A new version of openjdk18-openshift was released today (https://access.redhat.com/containers/?tab=overview#/registry.access.redhat.com/redhat-openjdk-18/openjdk18-openshift) and it looks like it has a bug when dealing with multi module maven projects.

The previously documented solution was to use "ARTIFACT_COPY_ARGS" which we were setting to "*/target" With the latest version of the s2i image, this results in the following warning/error...

WARN ARTIFACT_COPY_ARGS is deprecated. Please use S2I_SOURCE_DEPLOYMENTS_FILTER to specify artifact types and MAVEN_S2I_ARTIFACT_DIRS to specify the build output directories to copy from.
/opt/jboss/container/java/s2i/maven-s2i-overrides: line 44: pushd: /tmp/src/target: No such file or directory

If I set "MAVEN_S2I_ARTIFACT_DIRS" to "*/target" then there are no errors but nothing actually gets copied. Eventually I got it to work by hardcoding the module directories (e.g. "module1/target,module2/target").

I had to trace through all the source code because MAVEN_S2I_ARTIFACT_DIRS seems to be completely undocumented. I eventually found that I had to use commas to separate the list and I also found where the bug is...

https://github.com/jboss-openshift/cct_module/blob/master/jboss/container/s2i/core/bash/artifacts/opt/jboss/container/s2i/core/s2i-core

Line 94...
if [ -d "${1}/${S2I_SOURCE_DEPLOYMENTS_DIR}" ]; then

This returns false when using "*/target". It does not produce any error or logging but results in a failed image.

I believe the following changes should be made...

1. This code should be changed to support wildcards like it did previously.
2. The documentation for openjdk18-openshift should be updated for MAVEN_S2I_ARTIFACT_DIRS and the deprecation of ARTIFACT_COPY_ARGS.

3. The scripts should log warnings if source artifacts are not found
