java - 类型错误 : invokeMember GraalVM native-image

Question

我正在尝试使用 GraalVM 创建 native 镜像，我的代码:

import org.graalvm.polyglot.HostAccess;

public class Console {

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

然后我这样称呼代码本身:

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());


    }

当我通过 IDE 或 java -jar 运行时它工作正常，但是当我尝试编译为 native 镜像时会抛出错误。下面的错误后面是用于编译 native 镜像的命令行。

错误:

类型错误:JavaObject[com.compiler.commons.log.Console@113a2d320 (com.com.compiler.commons.log.Console)] 上的 invokeMember(打印)失败，原因是:未知标识符:打印

请问有人可以帮助我吗？非常感谢

我已经解决了，我需要从“/config”文件中清理，沿着代理执行应用程序，然后编译添加一些不同的参数。请参阅下面的内容:

代理

/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 

编译
