Store version in Java-Git projects

What is the best way to store the version of my application?

I use Git tagging to store a semantic version number in the Git repository. But I also want to print out the version number to the user of the program (f.ex. when a user calls ./myprogram --version). So I also had to manually change a String constant in my Java source code for every new version.

Is there a smarter way to keep the version numbers in the Git repository and the source code in sync?

In our project we use the git-commit-id-plugin for maven. You can generate something that can be read at runtime by your program, e.g., a Java class that contains static fields or a properties file that is read.

If you don't use maven, there surely is a plugin for your build tool or, at the very least, the possibility to somehow call git describe (as suggested by others).

You can get the current tag from git using

git describe [--abbrev=0] > localFileForTag

If you put that line into a script and run that script during the build process, you can store the current tag in a local file. Your program just has to read and print the file content.
