创建Spring Boot应用程序时出现问题

Question

i am still a beginner with spring boot, and i have a bunch of questions. First of all, do i have to download maven in my pc and add it to my pc path envirement to make spring boot work correctly ? Secondly, Spring boot wasn't able to work, was doing a hello world app and there were lot of errors on the console one of them is "SLF4J: Failed to load class "org.slf4j.impl.StaticLoggerBinder".. why that ? i looked for the error and followed some mvn command line steps "mvn dependency:purge-local-repository", and my app finally worked.. but do i have to run this command everytime i create a spring boot app ? isn't everything supposed to be alright since it's only a hello world app ? .. Thank you

Yes, you need to have installed maven or gradle in order to run your application. And it needs to be reachable, so you have to configure your system variables accordingly.

You can find more details here .

As per the maven error, maven keeps all the artifacts you need to run your application in a shared folder with all versions, sometimes maven could have corrupted files or a mismatch in version so you need to purge the repository and download artifacts again.

Even when you are coding a simple application, spring-boot bring up a lot of code for supporting operations you may require, such code is self configured and hidden.
