  Running and Building Gradle with Different JDKs - Sip of Java If you are using Gradle as the build tool for your projects and want to work with the latest JDK releases or early-access builds, you might think you are stuck until Gradle supports those versions of the JDK, which might take a few months. However, that’s not the case, and we will explore in this article how to run Gradle with one JDK version while building and testing with a different JDK version. Managing Multiple JDKs When working with multiple JDKs, using a tool like SDKMan or Jenv (for macOS) is highly recommended. These tools enable you to easily manage and switch between your local JDKs. This article assumes that you have multiple JDKs installed on your system: one for running Gradle, and the other for executing the tasks in the build.
