So when you write a blog or article, it is best to specify the scene, or you will get readers and friends into a lot of weird circles!
Then, if you are creating a maven project, and the packaging method is also war, and you still can’t find Java EE Tools, find articles on the Internet about converting the project to maven, and you can pass it directly, because these answers will Let you find the wrong direction to deal with the problem.
