maven打包web项目时同时打包为war和jar文件
首先在pom.xml文件中指定war的打包方式，war

然后在pom文件的plugins节点下面增加如下内容即可mvn package时同时生成war, jar包。为了 mvn package install, mvn package deploy能够同时部署jar包，我们增加了后面2节点的配置：

<!--  package jar on package -->
<plugin>
  <groupId>org.apache.maven.plugins</groupId>
  <artifactId>maven-jar-plugin</artifactId>
  <executions>
  <execution>
    <id>make-a-jar</id>
    <phase>compile</phase>
    <goals>
      <goal>jar</goal>
    </goals>
  </execution>
  </executions>
</plugin>
<!--  install jar to local repository -->
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-install-plugin</artifactId>
