About JEnv For Windows
JEnv for Windows is an open source command-line tool that changes the active Java version (JDK) on a Windows machine. It is written in cmd and PowerShell and works on Windows 10 and later. The repository describes it as useful for testing and for projects that need different Java versions. For example, a Gradle project that requires Java 8 can be built without changing environment variables, and the user can then switch back to Java 15.
Users register each JDK by name and path, then select a version for the current session, globally, or for a specific folder. The source notes that adding a JDK requires an absolute path, that some users reported problems when installing JEnv in C:\Programs because of admin rights, and that jenv may need to be called when entering a folder with a local version so that tools such as Maven work correctly.

JEnv For Windows FAQ
Can JEnv be used from both cmd and PowerShell?
Yes. The source says it is written in cmd and PowerShell. In cmd, you call the batch file. In PowerShell, you call src/jenv.ps1.
Why might Maven not use the expected Java version in a project folder?
The source says it is sometimes necessary to call jenv when entering a directory with a local jenv setting. This sets JAVA_HOME for the current shell, which helps tools like Maven work properly.
