VS Code required Java 11, but Azure Functions require Java 8 - How to modify settings.json

Question

Starting July Java 11 was required for Visual Studio Code. So I have installed Java 11. But Azure Function requires Java 8. I tried to configure VS to use both SDK.

Example: VSCode showing "Java 11 or more recent is required to run. Please download and install a recent JDK"

VS Code still trying to use Java 11. Is it possible to change to JDK 8??? [WARNING] Azure Functions only support JDK 8, which is lower than local JDK version 11.0.8.

JAVA_HOME env path

C:\Program Files\Zulu\zulu-11\

Settings.json for JAVA.HOME

{
  "azureFunctions.deploySubpath": "target/azure-functions/functionsjava",
  "azureFunctions.projectLanguage": "Java",
  "azureFunctions.projectRuntime": "~2",
  "debug.internalConsoleOptions": "neverOpen",
  "azureFunctions.preDeployTask": "package",
  "java.configuration.updateBuildConfiguration": "interactive",
  "azureFunctions.templateFilter": "All",
  "java.home": "C:/Program Files/Zulu/zulu-11",
  "java.configuration.runtimes": [
    {
      "name": "JavaSE-1.8",
      "path": "C:/Program Files/Zulu/zulu-8",
     "default": true
    },
    {
      "name": "JavaSE-11",
      "path": "C:/Program Files/Zulu/zulu-11",
  
    }
  ]
}

I have JAVA_HOME set to 8 and java.home in VS Code set to 11. Seems to work with Azure functions. — Daniel F

If you want to use jdk 8, then you should do like this:

"java.home":"C:\\Program Files\\Java\\jdk1.8.0_261",

By the way, azure function support java 11, but you need you use function v3:
