Eclipse adds Hadoop source code package

There is no Hadoop source code package in the Maven warehouse, and I can't find it directly on the Internet, so I downloaded the entire Hadoop-1.2.1 package on the official website, extracted the corresponding source code, packaged it and threw it to Eclipse, but it still couldn't be displayed ( strangeness,).

Solution steps:

1. Create a new Maven project in Eclipse, groupId is optional (org.apache.hadoop is not recommended), artifactId is hadoop-core, version 1.2.1, package is jar
2, put Hadoop source code into src/main/java
3. Edit pom.xml, import dependencies (see below for details)
4. Edit pom.xml, add corresponding plugins (javaDoc and source)
5. mvn install
6, update the reference to Hadoop in related projects
7, remember to change it back when publishing: )

, if there is a better solution, please let me know, thank you in advance.
