java - I can't run any version of swagger-fox. Spring Boot 2.4.2 + JDK 8

Question

This is the first time I can't get any version of swagger-fox up and running. Spring Boot 2.4.2 + JDK 8. I have previously added swagger-fox to my projects using the instruction below, but none fit.

Link on tutorial - https://www.baeldung.com/swagger-2-documentation-for-spring-rest-api

Failed Run - https://pastebin.com/G34kGMc3

P.S. Sorry, I went crazy and took the file from the wrong branch. I've updated the file.

question from:https://stackoverflow.com/questions/65899176/i-cant-run-any-version-of-swagger-fox-spring-boot-2-4-2-jdk-8

Answer 1

You should use recommended versions by the springfox-boot-starter as @eis has mentioned in comments you shouldn't override specified versions by spring boot starters unless you have an issue with recommended versions.

Removing version tag from springfox-swagger2 & springfox-swagger-ui dependencies from your pom.xml will fix the issue.

I also has configured swagger using the same tutorial several times, I noticed that springfox-boot-starter has been added recently. You don't need to delcare springfox-swagger2
