无法解决112.0:缺少需求[112.0] osgi.wiring.package；osgi.wiring.package

Question

我正在apache 3.0.3中创建一个简单的Echo服务包，我有我的Activator类，

package com.company.activator;

import org.osgi.framework.BundleActivator;
import org.osgi.framework.BundleContext;

public class Activator implements BundleActivator {

    private static BundleContext context;

    static BundleContext getContext() {
        return context;
    }

    /*
     * (non-Javadoc)
     *
     * @see org.osgi.framework.BundleActivator#start(org.osgi.framework.BundleContext)
     */
    public void start(final BundleContext bundleContext) throws Exception {
        Activator.context = bundleContext;
    }

    /*
     * (non-Javadoc)
     *
     * @see org.osgi.framework.BundleActivator#stop(org.osgi.framework.BundleContext)
     */
    public void stop(final BundleContext bundleContext) throws Exception {
        Activator.context = null;
    }

我可以使用下面的Mannifest文件通过eclipse创建Bundle

Manifest-Version: 1.0
Private-Package: com.company.activator
Built-By: noushad
Tool: Bnd-0.0.238
Bundle-Name: osgi
Created-By: Apache Maven Bundle Plugin
Build-Jdk: 1.7.0_76
Bundle-Version: 1.0.0
Bnd-LastModified: 1427119505629
Bundle-ManifestVersion: 2
Bundle-Activator: com.company.activator.Activator
Export-Packages: com.company.echo
Bundle-SymbolicName: com.company.osgi
Import-Package: org.osgi.framework;version="1.8"

另外，我有以下POM文件

    <project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/maven-v4_0_0.xsd">

                        <Bundle-Activator>com.company.activator.Activator</Bundle-Activator>

                </configuration>
            </plugin>
        </plugins>
    </build>
</project>

还有我的回声课

package com.company.echo;

public class Echo {

    public String echo(final String string) {
        return string;
    }
}

在karaf 3.0.3上部署此应用程序时，我将面临以下问题

1. 当我尝试启动包时，获取以下堆栈跟踪 错误:包com.company.osgi 112启动/停止包错误。( (&(osgi.wiring.package=org.osgi.framework)(version>=1.8.0))) org.osgi.framework.BundleException: osgi.wiring.package中未解决的约束:无法解决112.0:缺少需求112.0 osgi.wiring.package；(&(osgi.wiring.package=org.osgi.framework)(version>=1.8.0)) at org.apache.felix.framework.Felix.resolveBundleRevision(Felix.java:3974) at org.apache.felix.framework.Felix.startBundle(Felix.java:2037) at org.apache.felix.framework.Felix.setBundleStartLevel(Felix.java:1483) at org.apache.felix.framework.FrameworkStartLevelImpl.run(FrameworkStartLevelImpl.java:334) at java.lang.Thread.run(Thread.java:745)

有人能帮我弄清楚到底是什么问题吗。

提前谢谢..！

我不认为karaf 3支持OSGi Core R6 (org.osgi.framework包版本1.8)。您应该尝试针对另一个版本的OSGi API进行编译。
