Hello @nesrin-abdulmaksoud SpringBoot 2.2 will be supported by the upcoming Spring Cloud Hoxton Release Train. For now, with Greenwich, please use Boot 2.1.

Are you know why Boot 2.1.8 is not founding any UnitTests?

[jzlima]

i've the same error with 2.2.1.RELEASE in spring boot cloud gateway. today i'm using 2.1.9.RELEASE that works.

[modikanisha]

Update your springfox-swagger version. I have updated springfox 2.9.2 running with boot 2.2.2

SpringFox needs version 1.2.0 version but Spring Boot 2.2.2 itself does not pull this in.So you have to set spring-plugin-core-1.2.0.RELEASE in your classpath.Then it will work fine.

[grajuu]

2.2.4.RELEASE support version of cloud version is
<spring-cloud.version>Hoxton.M2</spring-cloud.version>

registry , actuator ,etc
Works for me .
Good luck
