使用maven将项目打成jar包

</pre>如果这个项目本身还依赖另一个项目A,那么我们就得先把项目A打成jar包使用上面的pom,然后在myeclipse中右键,run as maven install最后结果<p>如下图</p><p>lib下存放着edu-service-user运行所需要的jar</p><p>另外,我们之间在命令行下,使用java -jar edu-service-user.jar 即可调用</p><p>com.alibaba.dubbo.container.Main这个类</p><p><img src="https://img-blog.csdn.net/20160502222634711?watermark/2/text/aHR0cDovL2Jsb2cuY3Nkbi5uZXQv/font/5a6L5L2T/fontsize/400/fill/I0JBQkFCMA==/dissolve/70/gravity/Center" alt="" />

第二种方式

<pre name="code" class="html"><plugin><groupId>org.apache.maven.plugins</groupId><artifactId>maven-shade-plugin</artifactId><version>1.2.1</version><executions><execution><phase>package</phase><goals><goal>shade</goal></goals><configuration><transformers><transformer implementation="org.apache.maven.plugins.shade.resource.ManifestResourceTransformer"><mainClass>com.juvenxu.mvnbook.helloworld.HelloWorld</mainClass></transformer></transformers></configuration></execution></executions></plugin>  

运行mvn install 后 会在target下生成两个jar包original-xxx-0.0.1-snapshot.jar 这里面只有我们自己写的java代码的class文件xxx-0.0.1-snapshot.jar 这里面我们依赖的jar包(会抽出里面的class文件)会和我们的代码放在一块如下:toyprogram里面放的是我们自己写的java代码的class文件spring就放在org里面

还有一种方式

<plugin><artifactId>maven-assembly-plugin</artifactId><configuration><appendAssemblyId>false</appendAssemblyId><descriptorRefs><descriptorRef>jar-with-dependencies</descriptorRef></descriptorRefs><archive><manifest><mainClass>abc.ef.sdf</mainClass></manifest></archive></configuration><executions><execution><id>make-assembly</id><phase>package</phase><goals><goal>assembly</goal></goals></execution></executions></plugin> 然后在pom文件上右键 run as->maven assembly:assembly之后在pom的同级目录里会生成你所需要的jar不知道怎么回事,我的myeclipse里没有maven assembly:assembly不过可以这样run build... 然后参考资料http://www.blogjava.net/qileilove/articles/410887.htmlhttp://www.cnblogs.com/justinzhang/p/4983633.html
