查找损坏Jar

 find  ~/.m2/repository/ -name "*jar" | xargs -L 1 zip -T | grep error | grep invalid

向仓库中发布Jar包

mvn deploy:deploy-file -DgroupId=[GroupID] -DartifactId=[ArtifactID] -Dversion=[Jar Version] -Dpackaging=jar -Dfile=[Local Jar path]  -DrepositoryId=[Repository ID, define in POM] -Durl=[Remote Repository URL] -s [default setting.xml or special one]

Mvn依赖冲突相关

## 查看依赖树
mvn dependency:tree [-Dverbose -D...]

## 查看有效pom文件
mvn help:effective-pom

常用命令汇总

## 强制更新依赖
mvn -U

## 只加载依赖的项目
mvn -pl XXXProject -am

Maven Eclipse预处理

## 预先处理一下
mvn ... ## 编译完成
mvn eclipse:clean ## 清理
mvn eclipse:eclipse -DdownloadSources -DdownloadJavadocs -Pxxx -Dyyy

父子模块版本号

## 修改父版本号，刷新子模块的版本号
mvn -N versions:update-child-modules

一键发布

## 配置setting.xml
## 在setting.xml中配置 </servers>\<profiles>

## 在pom中添加
<distributionManagement>
        <!-- release -->
        <!-- snapshot -->
        <repository>
            <id>snapshots</id>
            <name></name>
            <url></url>
        </repository>
</distributionManagement>

## 直接发布
mvn clean deploy -DskipTests -s [SettingsPath]
