Read last commit of the git and commit number

Question

In maven project with Git source code, Is it possible whenever I am compiling a build with maven, to read the last commit of the git and commit number.

I want to use that commit number to be able to find the last commit.

This is assuming you want to read that information, then store it in a property file. Based on https://github.com/ktoso/maven-git-commit-id-plugin#using-the-plugin:

pom.xml:

            </plugin>
            <!-- END OF GIT COMMIT ID PLUGIN CONFIGURATION -->

            <!-- other plugins -->

git.properties in /src/main/resources:

git.commit.id=${git.commit.id}
