   ### Describe the bug
   
   When I follow the 
[developer-tools](https://kyuubi.apache.org/developer-tools.html) to build  a  
kyuubi submodule. I found error:
   ```shell
   jia@jia-pc:~/IdeaProjects/kyuubi$ build/mvn clean package -pl :kyuubi-common 
-DskipTests
   Using `mvn` from path: /home/jia/tools/apache-maven-3.6.3/bin/mvn
   [INFO] Scanning for projects...
   [ERROR] [ERROR] Could not find the selected project in the reactor:

   [ERROR] [Help 1]

   ```
   
   I use `mvn -help` to see `-pl` option:
   ```shell
    -pl,--projects <arg>                   Comma-delimited list of specified
                                           reactor projects to build instead
                                           of all projects. A project can be
                                           specified by [groupId]:artifactId
                                           or by its relative path
   ```
   
   So, I try a command use relative path or use `[groupId]:artifactId` as 
follows:
   ```
   build/mvn clean package -pl :kyuubi-common_2.12 -DskipTests
   build/mvn clean package -pl ./kyuubi-common -DskipTests
   build/mvn clean package -pl kyuubi-common -DskipTests
   ```
   They are all success to build the submodule.
   
   I think the doc have some error need to fix.
