How to know what distributions are available?

[martinandersson]

In settings.gradle:

plugins {
    id('org.gradle.toolchains.foojay-resolver-convention') version('0.7.0')
}

In build.gradle:

java {
    toolchain {
        languageVersion = JavaLanguageVersion.of(20)
        vendor = JvmVendorSpec.ORACLE
    }
}

If I swtich the version to 99, the build fails with this message;

Requesting vendor list failed: {"result":[],"message":"Requested version is not released yet."}

How can I know what version is released/available to the plugin?

I would kindly ask to update README.md with this information ❤️
