Looks like I can use the following command to determine the version number of Maven plugings: mvn dependency:tree -Dverbose
--- maven-dependency-plugin:2.8:tree (default-cli) @ --- Probably would be wise to install the latest Dependency Plugin 3.2.0 Thanks -----Original Message----- From: Greg Chabala <[email protected]> Sent: Tuesday, August 3, 2021 3:57 PM To: Maven Users List <[email protected]> Subject: Re: Unable to resolve artifact error when trying to transfer ISO using pom.xml ---- External E-mail --- CAUTION: This email originated from outside GDMS.

In general they are independent of the maven version, and you should feel free to upgrade to the latest version for any plugin. https://maven.apache.org/plugins/maven-dependency-plugin/ is at 3.2.0. https://www.mojohaus.org/versions-maven-plugin/ has a display-plugin-updates goal, along with other similar goals that can help you check if your project plugins are up to date.
