Hardware Requirements

  • 2GHz CPU

  • 10GB free hard drive space

Software Requirements

Java Environments

This version of Anypoint Studio requires Java 8 to run properly.
Depending on which Mule runtime you want to use, you can configure different JDK versions within Anypoint Studio:

  • Mule 3.9.x requires Studio running on Java 8.

  • Mule 3.5.x requires Studio running on Java 7.

  • Other supported runtime versions work fine with both Java 7 or 8.

Operating Systems

  • MacOS 10.10.0

  • Windows (32- and 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

  • Communication with Exchange fails when integrating with Anypoint Platform Private Cloud Edition.

Migration Guide

Since this version of Anypoint Studio upgrades its core Eclipse version, it is recommended to download and run the latest installer to install a fresh new full copy.

Updating your Anypoint Studio version using the update site does not update the bundled version of the Mule runtime.
To get the latest runtime version after updating Studio follow these steps.

When opening a previous workspace with projects that were created with Studio 5.1.0 or older, and which has metadata stored in disk, Studio asks you to perform an update to all the projects so that the Metadata Manager can handle the existing types and show them in your project.

You can easily import all of the external components that you had installed in your old version of Anypoint Studio through a single action. This includes connectors, runtimes, and any other type of extension added through the Anypoint Exchange or the ​Help → Install new software​ menu, as long as there are no compatibility restrictions.

Do this by selecting File→Import and then choose Install→From existing installation.


Then specify the location of your old version of Anypoint Studio in your local drive.
