Hi,

If you run maven dependency:tree, which version of the
maven-dependency-plugin do you see?
(Look for something like:
   [INFO] --- maven-dependency-plugin:3.1.2:tree (default-cli) @ your-module
)

And if it is something other than 3.1.2:
* Why aren't you using the latest version?
* Why don't you specify the plugins you are using in the pluginManagement
section of your company pom?

Ensuring the build environment is consistent is critical. Use the
pluginManagement section in the parent POM to declare explicit plugin
versions. This will nail down the plugin environment, removing potential
future conflicts. It’s still good practice to regularly check for and
update to the latest versions.

Hth,

Nick Stolwijk
