Maven搭建hadoop环境报Missing artifact jdk.tools:jdk.tools:jar:1.6

Maven引入Hadoop依赖报错：Missing artifact jdk.tools:jdk.tools:jar:1.6

1. <dependency>
2. <groupId>org.apache.hadoop </groupId>
3. <artifactId>hadoop-mapreduce-client-core </artifactId>
4. <version>2.4.0 </version>
5. </dependency>

原因是缺少tools.jar的依赖，tools.jar在jdk的安装目录中提供了，所以改成如下形式解决此问题：

1. <dependency>
2. <groupId>org.apache.hadoop </groupId>
3. <artifactId>hadoop-mapreduce-client-core </artifactId>
4. <version>2.4.0 </version>
5. <exclusions>
6. <exclusion>
7. <groupId>jdk.tools </groupId>
8. <artifactId>jdk.tools </artifactId>
9. </exclusion>
10. </exclusions>
11. </dependency>
12. <dependency>
13. <groupId>jdk.tools </groupId>
14. <artifactId>jdk.tools </artifactId>
15. <version>1.6 </version>
16. <scope>system </scope>
17. <systemPath>${JAVA_HOME}/lib/tools.jar </systemPath>
18. </dependency>
