Maven是Java项目的实时标准，掌握其使用技巧，可以提高工作效率
配置阿里巴巴源
settings.xml
<mirror>
<id>alimaven</id>
<name>aliyun maven</name>
<url>
http://maven.aliyun.com/nexus/content/groups/public/
</url>
<mirrorOf>central</mirrorOf>
</mirror>
配置本地存储位置
settings.xml
<localRepository>E:\m2_repository</localRepository>
只发布子模块
<properties>
<maven.deploy.skip>true</maven.deploy.skip>
</properties>
因为子模块会继承属性，所以需要发布的模块就要修改为true
<properties>
<maven.deploy.skip>false</maven.deploy.skip>
</properties>
只编译子模块
mvn clean package -pl mybaits-util
只发布父Pom
maven deploy -N（不会发布子module）
