maven 私服同步无法获取依赖的pom.xml的依赖

 

项目中引入了依赖：

<dependency>
<groupId>org.apache.hadoop</groupId>
<artifactId>hadoop-common</artifactId>
<version>2.6.0-cdh5.7.1</version>
</dependency>

但是通过公司的私服获取后得到此 jar 的 pom 文件为

<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">
<modelVersion>4.0.0</modelVersion>
<groupId>org.apache.hadoop</groupId>
<artifactId>hadoop-common</artifactId>
<version>2.6.0-cdh5.7.1</version>
<description>POM was created by Sonatype Nexus</description>
</project>

从上面看到没有任何依赖项,所以 maven 没有去下载，进而导致项目报错。

　

那么问题来了:maven 私服同步的时候回导致同步失败吗 ? 会什么会出现同步后的 pom 不同的情况?,还是公司的网络问题？

解决方法：1、手动一个一个加上这个jar所需要的dependency依赖，这样太傻了

              2、网上找一个这个jar的pom依赖文件，根据jar的groupId:artifactId:version去找对应的pom.xml 再去替换一下 

找到了如下：（部分）

<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">
<modelVersion>4.0.0</modelVersion>
<parent>
<groupId>org.apache.hadoop</groupId>
<artifactId>hadoop-project-dist</artifactId>
<version>2.6.0-cdh5.7.1</version>
<relativePath>../../hadoop-project-dist</relativePath>
</parent>
<groupId>org.apache.hadoop</groupId>
<artifactId>hadoop-common</artifactId>
<version>2.6.0-cdh5.7.1</version>
<description>Apache Hadoop Common</description>

<properties>

<is.hadoop.component>true</is.hadoop.component>

<wsce.config.file>wsce-site.xml</wsce.config.file>
</properties>
<dependencies>

<artifactId>guava</artifactId>

<dependency>
<groupId>commons-cli</groupId>
<artifactId>commons-cli</artifactId>
<scope>compile</scope>
</dependency>
<dependency>
<groupId>org.apache.commons</groupId>
<artifactId>commons-math3</artifactId>
<scope>compile</scope>
</dependency>
<dependency>
<groupId>xmlenc</groupId>
<artifactId>xmlenc</artifactId>
<scope>compile</scope>
</dependency>
<dependency>
<groupId>commons-httpclient</groupId>
<artifactId>commons-httpclient</artifactId>
<scope>compile</scope>
</dependency>
<dependency>
<groupId>commons-codec</groupId>
<artifactId>commons-codec</artifactId>
<scope>compile</scope>
</dependency>

最后再次编译获取后成功解决。
