See configure Private Cloud Edition in Studio for more information.

Projects Compatibility

Anypoint Studio creates workspaces in which you can create and group your projects. By default, the first time you open Studio, it creates a default workspace and stores all your projects in it. Your Mule application projects can not be fully compatible with workspaces created by a different version of Studio:

Projects created in a Studio 6.x.x or earlier workspace

These projects are not compatible with Studio 7 because they are Mule 3 projects.

Projects created in a 7.1.x workspace

Because Studio 7.2.0 simplified the configuration of the mule-artifact.json file, if you are importing a project created in a Studio 7.1.x workspace, see Updating Workspaces for instructions to update your project structure to a compatible format.

Projects created in a Studio 7.2.x or later workspace

Projects created in this workspace are fully compatible. You can use a project created in a Studio 7.2.x workspace without performing any extra task.

Hardware Requirements

  • MuleSoft recommends a minimum of 4GB of free RAM available on a developer workstation. As applications become complex, consider adding more RAM.

  • 8GB of memory.

  • 2GHz CPU.

  • 10GB free hard drive space.

Software Requirements



Java Environments

  • AdoptOpenJDK 8

This version of Studio is not compatible with Java 9, Java 10, or Java 11.

The only compatibility introduced for Java 11 is when using Mule runtime engine 4.2.0 or later. Studio still requires Java 8 to launch and run properly. You can install and configure Java 11 on your machine, but make sure to configure this JDK to be used by the embedded 4.2.x runtime running in Studio.
See Change the JDK from Studio for instructions on how to do this.

If you are experiencing issues booting up Studio, see the troubleshooting recommendations for Windows, Linux, or MacOS.

Operating Systems

  • MacOS 10.12.0

  • Windows (64-bit)

    • Windows 7

    • Windows 8

    • Windows 10

  • RHEL 7.0

  • Ubuntu 15.04 or later

Running real-time antivirus protection software on your operating system might have a negative impact on Anypoint Studio performance. Although this issue is prominent on Windows, it also occurs on Linux and macOS.

Although the steps to solve these performance issues vary depending on your antivirus software, a typical solution is to either allow or exclude the Anypoint Studio and java executables, the Studio install and workspace filesystem locations, or some combination of both. See examples of solutions for McAfee Viruscan, Windows Defender, and Symantec Endpoint Protection.

Known Issues

  • MUnit Studio plugin 2.1.5 does not work with this version of Studio.

  • Because the metadata propagation works differently in Studio 7, Datasense might display errors if your DataWeave code has references to unknown metadata either because you didn’t define the metadata before writing your code, or because your flow is still incomplete.
    See Understanding How DataSense Uses Mule Event Metadata and Transform Message Component for more information.
