Maven是Java項目的實時標(biāo)準(zhǔn)，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>

配置本地存儲位置

settings.xml

<localRepository>E:\m2_repository</localRepository>

只發(fā)布子模塊

<properties>
  <maven.deploy.skip>true</maven.deploy.skip>
</properties>

因為子模塊會繼承屬性，所以需要發(fā)布的模塊就要修改為true

<properties>
  <maven.deploy.skip>false</maven.deploy.skip>
</properties>

只編譯子模塊

mvn clean package -pl mybaits-util

只發(fā)布父Pom

maven deploy -N（不會發(fā)布子module）
