Setting Java Runtime in Visual Studio Code (VSCode)

As quoted from Microsoft Visual Studio code instructions, clear as mud.

Configure Runtime for Projects

As Java evolves, it’s common that developers work with multiple versions of JDK. You can map them to your local installation paths via the setting: java.configuration.runtimes. The setting has the following format:

"java.configuration.runtimes": [
{
    "name": "JavaSE-1.8",
    "path": "/usr/local/jdk1.8.0_201"
},
{
    "name": "JavaSE-11",
    "path": "/usr/local/jdk-11.0.3",
    "sources" : "/usr/local/jdk-11.0.3/lib/src.zip",
    "javadoc" : "https://docs.oracle.com/en/java/javase/11/docs/api",
    "default":  true
},
{
    "name": "JavaSE-12",
    "path": "/usr/local/jdk-12.0.2"
},
{
    "name": "JavaSE-13",
    "path": "/usr/local/jdk-13"
}
]

If that left you baffled a bit then continue on for clarification …

The missing detail, that should be present

Which means open open user settings json.

The keyboard shortcut is Ctrl Shift + P (Windows NT & Linux) CMD + Shift + P (Classic macOS ;-( )

Type in settings json

Select “Preferences: Open Settings (JSON)”

Now you can add an entry like the above, but matched to your environment.

Also, if your running Windows NT derived Windows your paths will need to be fancy garbage as follows with the ‘\\’ path delimiter: "C:\\Program Files\\Microsoft\\jdk-17.0.1.12-hotspot"
