How to check pom.xml for updated dependencies


I am fairly new to Maven and pom.xml. Is there a way I can find out which of my dependencies that are outdated, so that I can update version numbers in my pom.xml.

In other languages, for instance, Ruby has the command gem list outdated that gives me a list of dependencies (rubygems) I can update

I am using IntelliJ Idea if that can help.


Solution

  • You can do this with the Versions Maven Plugin. Check the following goals:

    Here is a sample output (taken from the examples):

    Checking for new dependency updates

    The display-dependency-updates goal will check all the dependencies used in your project and display a list of those dependencies with newer versions available.

    Here are some examples of what this looks like:

    svn checkout http://svn.codehaus.org/mojo/trunk/mojo/build-helper-maven-plugin build-helper-maven-plugin
    cd build-helper-maven-plugin
    

    Run

    mvn versions:display-dependency-updates

    Which produces the following output:
