Briefly
This is my first blog in the true sense, recording the longest problem I have solved since transcoding. It took me three days on and off to finally solve the problem. The sense of achievement is very powerful! I also shared with you my problem-solving process and reference articles, and also asked the opinions of my classmates who have worked (in the Internet industry).

Overview: IDEA configuration maven and lombok burst various errors

Solution: replace jdk16.0.1 with jdk1.8 (java8)
Original arrangement
Understand idea 2021.3 +jdk16.0.1
Process description
I watched the video of Mad God on bilibili to learn java, but the video of Mad God was a bit incoherent. There was a section where two things, maven and lombok suddenly appeared. I was confused and started to configure the environment. .
On the first day , I followed the online tutorial to configure maven and lombok, and there were all kinds of 黄色警告things. It took an afternoon to configure, and then I went to do other things.
The next day I went to idea and wrote a multi-threaded video according to Mad God's video. Not only 黄色警告did it not eliminate it, but 报错at the time I thought it was a problem with the idea version, so I tried to jump back from idea to 2020, but still reported an error, and then jumped back to 2019 , through some configuration, you can not report an error. Then do something else.
On the third day , when I opened the idea and ran the program, I found the following problems:
By consulting the information on the Internet, it can be inferred that it is a problem with the jdk version. But at this time, after many debuggings, the java version settings in the project structure and compile in IDEA are a bit confusing, and I don't know how to adjust it for a while.
So I consulted my undergraduate classmate. His suggestion was that it might be a jdk problem. Currently jdk8 is relatively stable, and enterprises use it more. He suggested that I try jdk8.
After thinking about it again and again, I decided to push it all over again, reinstall jdk8 and idea2021.3 (used to use it), and finally after a series of operations, I saw such a prompt, and I felt that it was probably OK.
It finally worked!
This time, the solution to the problem is basically relying on reading materials and asking classmates. In the future, I will try to find a good solution and share it!
Excellent article sharing

These are all very good articles that I think are written. These authors are very powerful. If you want the new version of IDEA to configure maven and lombok, it is enough to read these articles.
