添加本地依赖

如果有需要添加一个 jar 包到工程，且没有可用的如 nexus 的包管理服务，可以参考这里。

首先在工程创建一个目录 libs。

1
$ mkdir libs

然后，安装 jar 包到 libs 。

$ mvn org.apache.maven.plugins:maven-install-plugin:2.5.2:install-file \
  -Dfile=<path-to-jar> \
  -DgroupId=<group-id> \
  -DartifactId=<artifact-id> \
  -Dversion=<version> \
  -Dpackaging=jar \
  -DlocalRepositoryPath=libs

然后，修改 pom。
