How to prevent automatic JDK installation during Mendix Studio Pro installation

Issue

During the installation of Mendix Studio Pro, the installer automatically includes a bundled JDK (Java Development Kit), currently provided via Eclipse Adoptium (Temurin). Organizations with internal IT security policies that mandate the use of a specific, pre-approved JDK distribution may therefore need to prevent this automatic JDK installation and instead configure Mendix to use their organization’s existing, approved JDK. However, avoiding the installation of the bundled JDK during the Studio Pro installation process is not supported and cannot be skipped via a configuration option or installer parameter. This article clarifies the current limitations and explains the available approach for configuring Mendix to use an already installed and organization-approved Java environment.

Environment

Studio Pro (all versions)

Cause

The Mendix Studio Pro installer is designed to bundle a JDK to ensure all users have a compatible Java environment. This is intended to simplify the installation process and guarantee compatibility.

Solution/Workaround

Although not supported or recommended, there is a technical workaround to prevent the bundled Eclipse Adoptium JDK from being installed with Mendix Studio Pro. Since the JDK is downloaded as part of the installation process from an external resource, it is technically possible to block or blacklist that resource at the network level to prevent the download. However, this approach may cause the entire Studio Pro installation to fail or abort and is therefore not advised. The only practical (though still unsupported) alternative would be to complete the Studio Pro installation as normal and then manually uninstall the bundled Eclipse Adoptium JDK afterward, before configuring Mendix to use the organization’s approved Java distribution.
