Javascript 用graalVM替换nashorn

我正在将一个Javascript引擎从Nashorn迁移到GraalVm，它无法实例化GraalJSScriptEngine/ScriptEngine。 我尝试了不同的方法：

GraalJSEngineFactory factory =  new GraalJSEngineFactory();
GraalJSScriptEngine engine = factory.getScriptEngine();

我在上面遇到以下错误：

ScriptEngineManager providers.next(): javax.script.ScriptEngineFactory: Provider com.oracle.truffle.js.scriptengine.GraalJSEngineFactory could not be instantiated

java.lang.AbstractMethodError: Receiver class com.oracle.truffle.polyglot.PolyglotImpl does not define or inherit an implementation of the resolved method abstract buildEngine(Ljava/io/OutputStream;Ljava/io/OutputStream;Ljava/io/InputStream;Ljava/util/Map;JLjava/util/concurrent/TimeUnit;ZJZZZLorg/graalvm/polyglot/io/MessageTransport;Ljava/lang/Object;Lorg/graalvm/polyglot/HostAccess;)Lorg/graalvm/polyglot/Engine; of abstract class org.graalvm.polyglot.impl.AbstractPolyglotImpl.

执行like^时返回null。我还注意到，

ScriptEngineManager

实例中只有一个工厂（Nashorn）

我在类路径中添加了truffleAPI jar，并使用VM选项运行它：

-ea-XX:+UnlockExperimentalVMOptions-XX:+EnableJVMCI-Dpolyglot.js.nashorn compat=true

我在Java 13上运行它，并附带以下附加依赖项：
