I have a Jenkins job which runs mvn clean verify on a project. But some of integration tests fail due to 2 dependencies that cannot be resolved by the Shrinkwrap resolver.
The Jenkins server and slaves are in an internal network which does not allow access to the central repository. But we have a Nexus repository which has all the required packages.
When running the Jenkins job it finishes with UNSTABLE and two failing integration tests. Both messages look like this:

To resolve this issue I added a pre build step to download the artifacts. The logs show that the artifacts were downloaded:
Resolving artifact com.fasterxml.jackson.datatype:jackson-datatype-jsr310:pom:2.7.4 Resolved artifact com.fasterxml.jackson.datatype:jackson-datatype-jsr310:pom:2.7.4 from central (, releases+snapshots)
I also checked in manually: the pom files are in the local repository.
Why can't it resolve the artifacts which are clearly inside the local repository?
Finally I have found a way. I provide the settings.xml and set the target to "csettings.xml". Then I pass the argument to the build goals and options: "-Dorg.apache.maven.user-settings=$WORKSPACE/csettings.xml"
