GraalVM原生映像

Question

我正在尝试用GraalVM创建一个本地映像，我的代码是：

import org.graalvm.polyglot.HostAccess;

public class Console {

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

然后我把代码本身称为：

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());


    }

当我运行IDE或java-jar时，它可以正常工作，但当我尝试编译为本机映像时，会抛出一个错误。下面是用于编译本机映像的命令行。

错误：

TypeError:invokeMember（打印）在JavaObject[com.compiler.commons.log]上。Console@113a2d320（com.compiler.commons.log.Console）]失败，原因是：未知标识符：打印

命令行

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

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

谁能帮帮我吗？谢谢

我已经解决了，我需要清理“/config”文件，沿着代理执行应用程序，然后添加一些不同的参数进行编译。见下表：

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 

编写
