I have tried to install some few other extension of Java like Maven for Java, and I get the error in installing them as well.

Any suggestions?

Answer 1

Currently Java Extension Pack is available for Visual Studio Code, instead of Visual Studio.

To enable Java support on Visual Studio Code, you can manually:

1. Install JDK (not JRE) 11+. Because Language Support for Java requires JDK 11+ to launch itself.
2. [Optional] In VS Code's settings, point java.home to the home directory of your JDK. (it's automatically detected if it's pointed by JAVA_HOME, included in PATH, or installed in default locations.)

Or as mentioned by @user14479250, you can simply run the all-in-one installer, which will install VS Code, JDK 11 and Java extensions if missing.

• Mac: https://aka.ms/vscode-java-installer-mac

Answer 2

In Java on Visual Studio Code Update – November 2020, It's strongly recommended that installing the extension pack or Coding Pack for Java for Java development on VS Code. Please follow the above link to install Coding Pack for Java-Windows.
