今天碰到个错误 “The POM for … is missing, no dependency information available” even though it exists in Maven Repository ，这个只是找不到pom，关键连jar包依赖都找不到，关键是这个jar包

  <dependency>
            <groupId>io.springfox</groupId>
            <artifactId>springfox-swagger2</artifactId>
            <version>${swagger.version}</version>
        </dependency>

maven获取依赖得时候，优先读取本地，本地没有读远程,原因是没有指定公司得私有远程仓库

 <repositories>
        <repository>
            <id>snapshots</id>
            <name>snapshots</name>
            <url>http://nexus.xxx.com:8081/nexus/content/repositories/snapshots/</url>
        </repository>
    </repositories>
