Maven搭建hadoop环境报Missing artifact jdk.tools:jdk.tools:jar:

pond2539

　　eclipse创建maven项目后，在pom,xml中原来写法如下：

<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>

<artifactId>hadoop25</artifactId>
<version>0.0.1-SNAPSHOT</version>
<packaging>jar</packaging>
<name>hadoop25</name>
<url>http://maven.apache.org</url>
<properties>
<project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>

<dependencies>

</dependency>
<dependency>
<groupId>org.apache.hadoop</groupId>
<artifactId>hadoop-client</artifactId>
<version>2.5.2</version>
</dependency>
</dependencies>
</project>
　　此时，pom.xml报错提示为： Maven搭建hadoop环境报Missing artifact jdk.tools:jdk.tools:jar:1.7
　　原因是缺少tools.jar的依赖，tools.jar在jdk的安装目录中提供了
　　处理方式如下，在pom.xml中 增加jdk.tools的配置信息：
　　

<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">
