If you have an older Magnolia project then it's quite possible you will need to update your pom. The archetype to create Magnolia projects has had some updates over the last couple of years. The guide can help you understand how to bring your project up o the current standards.

Prerequisites

Be sure to have the latest version of Maven and Java.

  • Maven 3

  • Java 8

History

Version 1.2.2 of the magnolia-project-archetype was released in late 2015. This was around the time Magnolia 5.4.10 was being released. So if you created your project before 2016 then you will need to update your parent pom to align with the new standards.

           It would normally not be needed, since info.magnolia:magnolia-bundle-parent already imports it. (see below)
           The dependency to info.magnolia:magnolia-project needs to be BEFORE the dependency
           to info.magnolia:magnolia-bundle-parent, otherwise it doesn't work either.
           Also note that this is assuming magnolia-project and magnolia-ui-project have the same version number as
           magnolia-bundle-parent, which not always be true in the future.
           If you are using Maven 3, you should not need the 2 dependencies below, and all should be well.

Updating

Updating your older pom can be done using these steps.

  1. Create a magnoliaBundleVersion property.

    The magnoliaVersion now refers to the main project version, which is a collection of modules including the core. The magnoliaBundleVersion ties together a project with other resources. These numbers can diverge since a bundle release does not necessarily mean a new project release.

  2. Remove the magnoliaVersion property.

    The magnoliaVersion property exists in the bundle parent pom. There is no reason to manage it explicitly unless you are using it in the module descriptor.

  3. Update your javaVersion property.
  4. Remove the dependencies on magnolia-project and magnolia-ui-project.
  5. Update your bundle dependency to use the new magnoliaBundleVersion property.
  6. Update the maven-compiler-plugin to version 3.7.0.
