After upgrading EAP to 7.4.15, some integration Drools tests have started to fail.

 
Expected SUCCESS, but got FAILURE! Response: ServiceResponse[FAILURE, msg='Failed to create container scorecard with module org.kie.server.testing:scorecard:1.0.0.Final: java.lang.RuntimeException: The requested KieBase "KiePMML-Scorecard" does not exist', result='null'] expected:<SUCCESS> but was:<FAILURE>

Digging into traces:

[INFO] [talledLocalContainer] 10:32:12,639 INFO [org.drools.compiler.kie.builder.impl.ClasspathKieProject] (default task-2) Virtual file physical path = /home/gmunozfe/git/droolsjbpm-integration/kie-server-parent/kie-server-tests/kie-server-integ-tests-drools/target/cargo/configurations/wildfly23x/tmp/vfs/deployment/deploymentca04ae6074532a62/kie-pmml-7.75.0-SNAPSHOT.jar-1dfc2ecc51411097/content

As it is highlighted, the path ends with "/content", this is due jarPath doesn't exist:
https://github.com/kiegroup/drools/blob/53b1cd439d2a768924561dff2281d2694f736b71/drools-compiler/src/main/java/org/drools/compiler/kie/builder/impl/ClasspathKieProject.java#L498

Therefore "/content" is added, but no pom is there.

This EAP change WFLY-18544 seems to be related, as we can see now, each jar is only deployed once:

[gmunozfe@gmunozfe-thinkpadp1gen3 vfs]$ find . -name kie-pmml-7.75*.jar
./temp/temp17a762bef39b01fc/content-f87f0762d3e88fc2/WEB-INF/lib/kie-pmml-7.75.0-SNAPSHOT.jar

On the other hand, in previous versions of wildfly, we can find it i vfs twice:

[gmunozfe@gmunozfe-thinkpadp1gen3 vfs]$ find . -name kie-pmml-7.75*.jar
./temp/tempa383fca85b92fbf6/content-e8642b464f7c1e0e/WEB-INF/lib/kie-pmml-7.75.0-SNAPSHOT.jar
./deployment/deploymentc07e41394eb2de2b/kie-pmml-7.75.0-SNAPSHOT.jar-c878b10acb24a338/kie-pmml-7.75.0-SNAPSHOT.jar

Last one is the expected in drools code to create the container, however now it's not present.

As a result of this, container is not deployed and tests fail.

It's reproducible with this kie-server-integ-tests-drools test:
