Sharing local repo for dependencies and a separate local repo for project

When I use Jenkins to build project I have to make each Job to use its own local repo (a local dir in the workspace) to prevent concurrent build error:

withMaven(
  mavenLocalRepo: '.local-m2-repo'
) {
 sh 'mvn clean install -P docker,integration-test'
{{ }}}

Besides, I have to cleanup workspace after build to save disk space.

So every time the build starts it have to download all the dependencies and that really cost a lot of time.

So I think it will be nice If maven could share a local repo for dependencies and a separate local repo for current built project.

Then we can save time of download dependencies and also provide isolation to prevent concurrent build error.
