Maven project will not build - maven

Question

My question is about project build by maven in Jenkins.
I have a maven project in jenkins. When I build it locally, it works fine, when I build it through jenkins I get an error.
The Maven settings in jenkins are equal to the settings I have locally.
I am clueless as to why I get this error.
The error:
New build name is '#11_origin/develop'
Parsing POMs
ERROR: Failed to parse POMs
org.apache.maven.project.ProjectBuildingException: Some problems were encountered while processing the POMs:

Answer 1

The POM which you published even is not valid as XML.
e.g. where root "project" tag?
