Jenkins can't find maven setting.xml file outside Jenkins Home

Question

I have Jenkins running on CentOS server and I'm trying to set up a job that runs mvn clean install on a git project. Since I want to use a global maven repository for my whole server, I'm setting up my project to run maven using a setting file in a path outside Jenkins home:

When running the build, Jenkins can't find that settings.xml file:

...
[workspace] $ /var/lib/jenkins/tools/hudson.tasks.Maven_MavenInstallation/Maven_3.0.4/bin/mvn -f firma-digital-service/pom.xml -s /home/dcalderon/.m2/repository/settings.xml -X clean package

When running the exact same commands Jenkins runs via command line everything works correctly which show that the file does exist in the server. What am I doing wrong? Is it an issue regarding user restrictions?

Answer 1

I am using the scripted pipeline and in my case added/updated the settings.xml file located at /var/lib/jenkins/.m2/ folder.

Answer 2

As an extension answer, when there are no specific changes to configuration, we can also say to use default settings for maven in the Jenkins configuration as mentioned below:

Settings file: Use default maven settings Global Settings file: Use default maven global settings

Answer 3

Jenkins runs as jenkins user so it can't see a file located in /home/dcalderon folder

Answer 4

you can use this plugin - https://wiki.jenkins-ci.org/display/JENKINS/Config+File+Provider+Plugin to manage the settings.xml.

just provide the relevant file to your project using this plugin.

Thanks , Mor
