一：创建maven项目，在pom.xml里面加入如下依赖

com.lala.Activator.java为

package com.lala;
    
    import org.osgi.framework.BundleActivator;
    import org.osgi.framework.BundleContext;
    
    public class Activator implements BundleActivator
    {
    	public void start(BundleContext context) throws Exception 
    	{
    		System.out.println("-----------start----------");
    	}
    
    	public void stop(BundleContext context) throws Exception 
    	{
    		System.out.println("-----------stop----------");
    	}
    }

二：配置插件

方法1：

<plugin>
    	<groupId>org.apache.maven.plugins</groupId>
    	<artifactId>maven-jar-plugin</artifactId>
    	<version>2.3.1</version>
    	<configuration>
    		<archive>
    			<manifestEntries>
    				<Bundle-ManifestVersion>2</Bundle-ManifestVersion>
    				<Bundle-Name>${project.groupId}.${project.artifactId}</Bundle-Name>
    				<Bundle-SymbolicName>${project.groupId}.${project.artifactId}
    				</Bundle-SymbolicName>
    				<Bundle-Version>${project.version}</Bundle-Version>
    				<Bundle-Vendor>${project.groupId}</Bundle-Vendor>
    				<Bundle-Activator>com.lala.Activator</Bundle-Activator>
    				<Export-Package>
    					com.lala.api
    				</Export-Package>
    				<Import-Package>
    					org.osgi.framework
    				</Import-Package>
    			</manifestEntries>
    		</archive>
    	</configuration>
    </plugin>

然后，执行mvn package，即可生成含有MANIFEST.MF文件的jar

方法2：

<plugin>
    	<groupId>org.apache.felix</groupId>
    	<artifactId>maven-bundle-plugin</artifactId>
    	<version>2.5.4</version>
    	<extensions>true</extensions>
    	<configuration>
    		<instructions>
    			<Bundle-ManifestVersion>2</Bundle-ManifestVersion>
    			<Bundle-Name>${project.groupId}.${project.ArtifactId}</Bundle-Name>
    			<Bundle-SymbolicName>${project.groupId}.${project.ArtifactId}</Bundle-SymbolicName>
    			<Bundle-Version>${project.version}</Bundle-Version>
    			<Bundle-Vendor>${project.groupId}</Bundle-Vendor>
    			<Export-Package>com.lala.api</Export-Package>
    			<Bundle-Activator>com.lala.Activator</Bundle-Activator>
    			<Import-Package>org.osgi.framework</Import-Package>
    		</instructions>
    	</configuration>
    </plugin>

然后，执行

mvn clean org.apache.felix:maven-bundle-plugin:bundle , 即可生成含有MANIFEST.MF文件的jar

或者把package声明为bundle

如：<packaging>bundle</packaging>

然后，就可以直接使用mvn clean package
