At present, there are defects in the chapter on debugging FE in doc. My colleagues and I stepped on the pit when building the debugging environment, so I want to improve this chapter in combination with my own stepping on the pit experience. The following is my explanation of the changes: 1. mkdir -p ./thirdparty/installed/bin explain: When I downloaded versions 0.14 and 0.15, there were no files under thirdparty, so I didn't know whether to create it myself or what to do. Finally, I decided to create it myself. I think it's necessary to add instructions here. 2. Add installation thrift@0.13.0 Failed handling method. explain: My colleagues and I failed to find the installation package when executing the installation command, and finally found a solution on GitHub. Therefore, I added the handling method of the problem to avoid other Mac users from getting stuck in this place. 3. Fixed an error in the generated code description. explain: Before I finished building the code, I debugged FE, and I failed all the time. Idea hints that no files can be found. Later, after consulting with morningman in wechat group, it was understood that `mvn install -DskipTests` does not need to execute `mvn generate-sources` after execution. This is inconsistent with the description in the document and needs to be corrected.
