So, I am trying to set up a CI/CD pipeline with the s4sdk. I successfully completed all the steps descriped in this blog. Everything seems to be running smoothly, however my build is failing with the following error message:
The following artifacts could not be resolved: com.sap.xs2.security:security-commons:jar:0.28.6, com.sap.xs2.security:java-container-security:jar:0.28.6, com.sap.xs2.security:java-container-security-api:jar:0.28.6, com.sap.security.nw.sso.linuxx86_64.opt:sapjwt.linuxx86_64:jar:1.1.19: Could not find artifact com.sap.xs2.security:security-commons:jar:0.28.6 in s4sdk-mirror (http://s4sdk-nexus:8081/repository/mvn-proxy/)
Now, this error messages makes sense to me, since I remember downloading these artifacts from the SAP download center and therefore those artifacts are not available on maven central.
I think this error can be resolved by manually uploading those artifacts to the nexus server, but I don't know how. According to the nexus documentation, there is a web ui reachable under http://< cx-server-ip>:8081, but it is somehow not responding.
I can confirm with docker ps that both the jenkins and nexus container are running and that the nexus container is listening on TCP 8081. I am also able to reach the jenkin's frontend to configure and run my pipeline.
What am I missing? Is uploading the missing artifacts to the nexus the right approach? Any help is appreciated.
The nexus container you see acts as a download cache and is by design not accessible from outside to prevent accidental changes to it. Also, its life-cycle is controlled by the cx-server script, so even if you installed packages there manually, they would be gone once you upgrade the Jenkins.
I think the best way to handle this would be to set up another Nexus instance where you install the required packages and configure the pipeline to use that as described here (mvn_repository_url). This nexus needs to be configured as a mirror for Maven central. We don't have specific docs on how to do that, but this post describes a similar setup.
In this set up, you might want to disable the download cache as it is redundant (cache_enabled to false).
I hope this helps.
Kind regards
