Multiple versions of spring boot

Question

I am running a Spring app and getting the following error: java.lang.IllegalStateException: Error processing condition on org.springframework.boot.autoconfigure.websocket.WebSocketAutoConfiguration$TomcatWebSocketConfiguration.websocketContainerCustomizer

A similar question has already been answered in this question. In the accepted answer, Gergely Bacso states that the problem is multiple versions of Spring Boot.

The stack trace lists the error happening in SpringBootCondition.java, and when I try to click to it I am offered two different releases of Spring Boot, as seen in the image below:

My questions are: 1) is this why I'm getting this exception? And 2) if so, how do I get rid of the extra version? (or alternately, if not, any other idea why this is happening?)

For reference, here is my pom.xml

Here's my application.yml:

security:
  jwt:
    token:
      secret-key: secret-key
      expire-length: 300000 # 5 minutes duration by default: 5 minutes * 60 seconds * 1000 miliseconds

UserController:
  signin: Authenticates user and returns its JWT token.
  signup: Creates user and returns its JWT token
  delete: Deletes specific user by username
  search: Returns specific user by username
  me: Returns current user's data

And when I run my maven dependency-tree I see this:

SpringBoot 2.2.0 was juste release a few days ago, maybe there is something about that. But you don't seem to import other dependency that themselves depends on another SpringBoot version, weird — Olivier L. Applin, Commented Oct 20, 2019 at 2:09
I see that SpringBoot 2.2.0 was added recently in my Project Structure-->modules. But when I try to take it out, Spring doesn't compile correctly at all, even when I take out any code I added since before I added it. — jimboweb, Commented Oct 20, 2019 at 2:38
try changing <version>1.5.6.RELEASE</version> to 2.2.0.RELEASE maybe ? — Olivier L. Applin, Commented Oct 20, 2019 at 2:52
Usually you should never defined versions yourself which are inherited via Spring. Apart from that I can't reproduce with the given pom your problem...Have tried to build on plain command line? — khmarbaise, Commented Oct 20, 2019 at 8:50

Okay, I figured it out. I went to File-->Project structure, and saw spring-boot-starter-test.2.2.0 in there. When I removed it, at first I didn't know what was going on because I had previously excluded the log4j.logger-classic module because of a different clash with a version of log4j, so when the program ran correctly I didn't see the log and didn't know it was running.

If you have a similar problem and can't figure it out comment on this and I'll try to help you.
