Version Settings for Mule, Java, and Connectors

Set Mule runtime engine (Mule), Java, and connector versions to use in your projects.

Select Default Mule and Java Versions

Select the default Mule and Java versions for new implementation and integration projects. The defaults appear in drop-down menus from which you select a version, for example, when creating a project.

Versions not present in the IDE append a message similar to downloads upon project creation. Versions that don’t support a feature typically append a message, such as AsyncAPI implementation unsupported for Mule 4.4.

You can set a different version at the project level (see Select Mule and Java Versions for a Project).

To select the default Mule and Java versions from the Settings tab:

  1. Open the Settings tab for the IDE:

    Show me how

    • From the Anypoint Code Builder panel, click the (gear) icon.

    • From the activity bar, click the (gear) icon, select Settings, and search for mule in the Settings tab.

    • Provide the command MuleSoft: Open ACB Settings in the Command Palette.

  2. Find Mule › Application: Default Mule Runtime And Java Versions in the open tab.

  3. Click Edit defaults through command palette.

    Although it is also possible to set the versions as values to muleRuntimeVersion and jdkVersion items directly in the Settings tab, you must know the major, minor, and patch numbers, and in some cases, the timestamp. It is easier to set them after clicking Edit defaults through command palette.

  4. Select a Mule runtime version.

  5. Select a Java version.

Select Mule and Java Versions for a Project

Set Mule or Java versions for a specific implementation or integration project from Project Properties. You can change versions at any time, but it is important to test your projects with the versions you intend to deploy.

Version settings are important in several scenarios:

  • Updating a project to use more current versions

  • Switching to a supported version, for example, for a project that you import into Anypoint Code Builder that uses an unsupported version

  • Adding a version of Mule or Java that is missing from your project

  • Selecting versions of Mule or Java that are compatible with each other

When a Mule or Java version is unset for a project, the IDE’s canvas and notifications provide a Set version button that opens the Project Properties tab. You can also navigate directly to the Project Properties tab.

To select Mule and Java versions for a project:

  1. Open your implementation or integration project.

  2. In the Explorer, right-click a configuration XML file in your project directory, and select Project Properties from the menu.

  3. In Project Properties, select the versions to use in this project.

Select Connector Versions for a Project

Set connector versions for a specific implementation or integration project from Project Properties. You can change versions at any time, but it is important to test your projects with the versions you intend to deploy.

To select connector versions for a project:

  1. Open your implementation or integration project.

  2. In the Explorer, right-click a configuration XML file in your project directory, and select Project Properties from the menu.

  3. Click Connectors from the Project Properties side bar.
