libyear-maven-plugin

This Maven plugin implements the libyear dependency freshness measure, showing you how many years behind the latest version each of your dependencies are.

When executed, you'll see an output like this for each of your modules:

[INFO] The following dependencies in Dependencies have newer versions:
[INFO]   io.quarkus:quarkus-arc ................................. 0.27 libyears
[INFO]   io.quarkus:quarkus-junit5 .............................. 0.27 libyears
[INFO]   io.quarkus:quarkus-junit5-mockito ...................... 0.27 libyears
[INFO]   io.quarkus:quarkus-rest-client ......................... 0.27 libyears
[INFO]   io.quarkus:quarkus-resteasy ............................ 0.27 libyears

The plugin requires JDK 11+. It is heavily based on the MojoHaus Versions Maven Plugin.
