== Auto-detection of installed toolchains

By default, Gradle automatically detects local JRE/JDK installations so no further configuration is required by the user.
The following is a list of common package managers, tools, and locations that are supported by the JVM auto-detection.

JVM auto-detection knows how to work with:

-------------------

The //go:uintptrkeepalive directive must be followed by a function declaration.

It specifies that the function's uintptr arguments may be pointer values that
have been converted to uintptr and must be kept alive for the duration of the
call, even though from the types alone it would appear that the object is no
longer needed during the call.

This directive is similar to //go:uintptrescapes, but it does not force

	fmt.Println("%v", "hi")                     // ERROR "Println call has possible Printf formatting directive %v"
	fmt.Println("%T", "hi")                     // ERROR "Println call has possible Printf formatting directive %T"
	fmt.Println("0.0%")                         // correct (trailing % couldn't be a formatting directive)
