Currently used version of the git-commit-id-plugin maven plugin (2.1.9) doesn't work with recent git structures. This is for majority of the users not manifested since Arrow has the java maven root in the project subdirectory (/java) instead of top level so this plugin normally doesn't kick in if maven is executed from the subdirectory (usual case - ie cd java; mvn install - works fine) as the plugin doesn't see the .git directory but it does kick in and fail if executed from the main arrow top level dir as mvn -f java/pom.xml install (where the .git sits):
$ mvn -f java/pom.xml package

Simple fix is upgrading the plugin to recent version (the minimal working version appears to be 2.1.13).
This is required for seamless integration with Jenkins (ARROW-1234).
