I am new to Micro-services and was following a course on it. Adding spring-cloud-starter-openfeign maven dependency throws a build error and all the other dependencies start complaining about resolve issues. I am using latest Spring Boot- 2.6.0 version, so I am guessing there might me compatibility issue as the spring-boot 2.6.0 is quite latest.

It's only the issue with openfeign, as I created a micro-service with spring-cloud-starter-config, and wanted another micro-service to call it's api through openfeign, but unable to do so.

Any discussion on what's wrong would be helpful.

P.S:

I am bootstrapping the project from Spring Initilaizr

I am using spring-cloud-dependencies version 2021.0.0-RC1

Adding the pom.xml for reference

  • I created a spring boot project with `spring-cloud-starter-openfeign` dependency but with java version 11, and there is no issue in project compilation. U can try with java version 8 or 11. – Urvashi Soni Nov 24 '21 at 13:01

    There is no Spring Cloud version for Spring Boot 2.6. You have to wait for a compatible version. – M. Deinum Nov 24 '21 at 13:02
  • @Uravshi Soni I have JDK `17` so I guess I'll have to switch to JDK 11 till a compatible version is released for Spring Boot 2.6 like @M. Deinum said. Thanks anyways – Nikhil Bhutani Nov 24 '21 at 18:29
  • Why would you need to downgrade to JDK11? Spring Boot 2.5 and Spring 5.3 support Java17, so not sure why you think you need an upgrade for that. – M. Deinum Nov 24 '21 at 18:42

    Yes, I have worked on prior projects with `spring-boot 2.5.7` and `JDK 17` but the only issue is with `spring-cloud-starter-open-feign`. I changed the JDK to `11` and used `spring-boot-2.6.0` it works perfectly fine without any dependency issue. – Nikhil Bhutani Nov 26 '21 at 04:58
