Variable: RuntimeComponents

const RuntimeComponents: {
  JAVA_RUNTIME_ALPHA: "java-runtime-alpha";
  JAVA_RUNTIME_BETA: "java-runtime-beta";
  JAVA_RUNTIME_DELTA: "java-runtime-delta";
  JAVA_RUNTIME_EPSILON: "java-runtime-epsilon";
  JAVA_RUNTIME_GAMMA: "java-runtime-gamma";

};

Defined in: src/types/runtime.ts:11

Mojang Java-runtime component identifiers. New components appear over time (e.g. java-runtime-delta for Java 21).

The launcher must respect the javaVersion.component field declared by the per-version Minecraft manifest. This list captures the set we have direct knowledge about; unknown components are still allowed and resolved dynamically against the runtime index.
