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

    <artifactId>test</artifactId>
<name>test</name>
<packaging>war</packaging>  

上述代码在eclipse中执行maven install时， 会默认打成war，并放入本地仓库。

web项目时同时打包为war和jar文件
1、首先添加在pom.xml中添加插件 maven-jar-plugin ， 使得 在调用命令mvn package install 或者 mvn package deploy 先生成 jar包。或者使用mvn package生成jar包。该插件生成的架包会放在工程的target文件夹下。

2、然后配置maven-install-plugin 插件， 使得在eclipse中执行maven install时, 同时生成jar和war到本地仓库。

3、再配置org.apache.maven.plugins插件， 使得在eclipse中执行deploy 时, 同时，生成jar和war到远程仓库。
