maven打包

https://maven.apache.org/download.cgi apache maven

-Dmaven.multiModuleProjectDirectory=$MAVEN_HOME
下面我们用一个命令验证一下本地库的配置，在命令行cmd，输入：mvn help:system

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。
