How do I install a POM in my local m2 repository?

Question

I need to install a parent POM (without a JAR file) into my local .m2 repository. mvn install:install-file won't let me do that, it always asks for a valid -Dfile=<path-to-jar>.

How can I install tmp/dependency-management-1.0.0-SNAPSHOT.pom?

Answer 1

While you need to specify -Dfile, you can tell mvn install:install-file to ignore the file and just install the POM with -Dpackaging=pom:

mvn install:install-file \
    -Dpackaging=pom \
    -Dfile=tmp/dependency-management-1.0.0-SNAPSHOT.pom \
    -DpomFile=tmp/dependency-management-1.0.0-SNAPSHOT.pom

will just install the POM, ignoring the value passed as file.

Note that file is not ignored! Whatever you specify as file will be copied to the .pom file in the local repository, e.g. if you specify a .jar file the .pom file will be binary identical to it. This is at least the case with maven-install-plugin:3.1.1. – Fribble
