I don't really use Maven that much but I do build Jenkins from time to time.
Jenkins has at least two ways of doing a Maven build.
1) If you choose a "maven2/3 project" type when creating a job,
Jenkins will not call mvn.bat when building. Instead it will load
Maven classes and call them directly. I believe it will use the same
jvm as is used to run Jenkins itself. I.e. use the same jvm for
running Jenkins.
2) If you choose a freestyle project when creating a job, you can
freely specify the command to run your build and set any environment
variables the way you want. This would allow you to build your Maven
project with a different jvm than used to run Jenkins. You will lose
some things... you have to tell Jenkins where the test results are
found and where are the build artifact to archive.
