java - 在 context.getBundle(0).adapt(FrameworkWiring.class).getDependencyClosure(bundles) 上使用 Maven 编译包时出错

Question

关于使用代码进行 bundle 编译

    package ihtika2.mainform;

import com.google.code.ihtika.Vars.Ini;
import ihtika2.mainform.service.MainFormInterface;
import java.util.HashSet;
import java.util.Hashtable;
import org.osgi.framework.Bundle;
import org.osgi.framework.BundleActivator;
import org.osgi.framework.BundleContext;
import org.osgi.framework.InvalidSyntaxException;
import org.osgi.framework.ServiceReference;
import org.osgi.framework.wiring.FrameworkWiring;

public class Activator implements BundleActivator {

    @Override
    public void start(BundleContext context) throws Exception {
        Hashtable<String, String> props = new Hashtable<String, String>();
        props.put("Funct", "MainForm");
        context.registerService(MainFormInterface.class.getName(), new MainForm(), props);

        ServiceReference[] refs = context.getServiceReferences(
                MainFormInterface.class.getName(), "(Funct=MainForm)");
        if (refs == null) {
            System.out.println("Not Found MainForm on start");
        } else {
            MainFormInterface MainForm = (MainFormInterface) context.getService(refs[0]);
            MainForm.sendContext(context);
            MainForm.showWindow();
        }

        int x = 0;
        for (Bundle qqq : context.getBundles()) {
            if (x < 1) {
                HashSet<Bundle> bundles;
                bundles = new HashSet<Bundle>();
                bundles.add(qqq);
                HashSet<Bundle> depends = (HashSet<Bundle>) context.getBundle(0).adapt(FrameworkWiring.class).getDependencyClosure(bundles);
                System.out.println("---");
                System.out.println(qqq.getSymbolicName());
                System.out.println("+++");
                for (Bundle depends1 : depends) {
                    System.out.println(depends1.getSymbolicName());
                }
            }
                x++;
        }

我收到错误

请告诉我，如何编译这段代码？我使用apache-maven-2.2.1，jdk1.7.0_06，编译1.6代码(在NetBeans项目中设置)。有趣的是 - NetBeans 不会在此字符串 (Activator.java:[38,109]) 上显示错误，并认为此代码是正确的。

您需要使用 osgi.core 4.3 或更高版本。 FrameworkWiring 类型是在 osgi.core 4.3 中引入的。 http://mvnrepository.com/artifact/org.osgi/org.osgi.core/4.3.0

Apache Felix 4.0 添加了对 osgi.core 4.3 的支持。 http://www.infoq.com/news/2011/09/felix-400
