Importing a Maven Project into Studio
|Mule Runtime Engine versions 3.5, 3.6, and 3.7 reached End of Life on or before January 25, 2020. For more information, contact your Customer Success Manager to determine how you can migrate to the latest Mule version.|
If you have a Mule project that was built using Maven outside Anypoint Studio, you can still import it into Studio and continue to work on it with the benefits of the Studio IDE.
|Important: if you use the Maven studio:studio goal, you cannot use the m2ecplipse plugin, because it will override the studio:studio goal. Anypoint Studio has built in capabilities for importing and exporting between Maven and Studio using the studio:studio goal, which covers most use cases.|
Studio has a built-in functionality to import a Maven project.
In Studio, go to File > Import…
Select Mule > Maven-based Mule Project from pom.xml, then click Next.
Navigate to the location of the pom.xml file you wish to import. Mule will automatically populate a Project Name, but you can adjust it.
Be sure to select the runtime you wish to use. Check Copy project into workspace if you want to create a copy of your project that resides in your workspace.
Anypoint Studio then internally runs the studio:studio goal and imports the Maven project into Studio, building the folder structure and files based on the instructions in the POM.
After you open your Maven project in Studio you might encounter error messages (as illustrated below). You may need to set the M2_REPO classpath variable or, if it has already been set, re-point it to the correct repository.
In Studio, right-click your project’s name in the Package Explorer, then select Properties.
In the Properties pane, click Java Build Path in the menu on the left, then click the Libraries tab.
Click Add Variable….
In the New Variable Classpath Entry panel, click the Configure Variables… button.
M2_REPOitem from the list of classpath variables, then click Edit….
M2_REPOdoes not appear as an item in the list of classpath variables, click New… to create this classpath variable.
Change the contents of the Path field to specify the location of your Maven (
Click OK in each of the open panels to save your changes.
Click the Problems tab in the console to confirm that the errors are no longer listed, which means they have been resolved.
You might also encounter the error below:
Failed to execute goal on project schema-extractor-plugin: Could not resolve dependencies for project org.mule.tooling:schema-extractor-plugin:maven-plugin:1.0-SNAPSHOT…
