Describe the feature

Using header properties provided from git, like license.git.copyrightLastYear, can be slow,
even used together with

<licenseSets>
  <licenseSet>
    <properties>
       <license.git.maxCommitsLookup>1</license.git.maxCommitsLookup>
    </properties>
...

That's because the two Property providers in com.mycila.maven.plugin.license.git use seperate JGit rev walks for (nearly) every property their provide, and all properties are eagerly provided.

For projects not using all provided properties to build header text this will result in unnecessary rev walks.

Any alternative you've considered ?

No.
