類型錯誤：invokeMember GraalVM native-image

Question

我正在嘗試使用 GraalVM 創建本機圖像，我的代碼：

import org.graalvm.polyglot.HostAccess;

public class Console {

    @HostAccess.Export
    public void print(String msg){
        System.out.println(msg);
    }
}

然后我像這樣調用代碼本身：

public void callMethod(CommonRequest request) throws ScriptException, IOException, NoSuchMethodException {
        StringBuilder s = new StringBuilder();

        s.append(new PluginJS().load(request.getMethodPath(), true));

        Context context = null;
        try {
            context = Context.newBuilder()
                    .allowHostAccess(HostAccess.ALL)
                    .allowAllAccess(true)
                    .allowCreateThread(true)
                    .allowHostClassLoading(true)
                    .allowIO(true)
                    .allowNativeAccess(true)
                    .allowCreateProcess(true).build();

            putMembers(context.getBindings("js"));

            context.eval("js", s.toString());

        } catch (Exception e) {
            e.printStackTrace();

        } finally {
            context.close();

        }

    }

    private void putMembers(Value value) { 
        value.putMember("Console", new Console());


    }

當我通過 IDE 或 java -jar 運行時它工作正常，但是當我嘗試編譯到本機映像時會引發錯誤。 在錯誤后面跟着用於編譯本機映像的命令行。

錯誤：

類型錯誤：JavaObject [com.compiler.commons.log.Console@113a2d320 (com.compiler.commons.log.Console)] 上的調用成員（打印）失敗，原因是：未知標識符：打印

命令行

graalvm-ce-java8-20.0.0/Contents/Home/bin/native-image --language:js --initialize-at-build-time nomeApp -jar compiler-1.0-SNAPSHOT-jar-with-dependencies.jar

請問有人可以幫我嗎？ 多謝

我已經解決了，我需要清理“/config”文件，沿着代理執行應用程序，然后編譯添加一些不同的參數。 見下文：

代理人

/Users/ze/Documents/programs/graalvm-ce-java8-20.0.0/Contents/Home/bin/java -jar -agentlib:native-image-agent=config-merge-dir=/Users/ze/Documents/gitprojects/java/tool/config ./target/compiler-1.0-SNAPSHOT-jar-with-dependencies.jar 

編譯
