Use content of an external file as the version value in pom.xml

I would like to have an external file, containing a single value - a version, such as 1.0 Then, I would like to reference this in my pom.xml, such that the version property will be set during build by the value I give to it This way I can have proper versioning on my jar without commiting changes using mvn to the entire reactor every time For example, something like:

<version>./version.txt</version>

And if the content of version.txt is 1.0, when I compile my code to a jar, mvn will evaluate the content of my file and set the jar version to 1.0

It slightly differs from properties file since my external file is not a key=value formatted file, its merely a value which I want to read in full and have it represent the value of a key in my pom.xml

You can achieve this by running the maven versions plugin before running your build

Your build script could loook something like this:

mvn -B -DnewVersion=$(cat ./version.txt) -DgenerateBackupPoms=false versions:set
mvn -B clean install
