Needs build instructions

[JetForMe]

I'm trying this demo on macOS. But you need some command-line build instructions. What gradle command do I invoke? I tried gradle jar, and that did something, but the results are in build/libs, not target.

Anyway, trying to run that jar, I get:

$ java -jar build/libs/microservices-demo-1.1.0.RELEASE.jar registration
no main manifest attribute, in build/libs/microservices-demo-1.1.0.RELEASE.jar

gradle build works better, but I get:

$ java -jar build/libs/microservices-demo-1.1.0.RELEASE.jar registration

Updating spring-boot to 1.4.3.RELEASE seems to fix the exceptions.

[Amalraj7692]

Hi JetForMe, where have you updated the Spring-Boot version. In the pom.xml ?

[JetForMe]

I was using Gradle, so it would've been in the gradle build file.

[Amalraj7692]

But I am trying to do from Eclipse IDE.

You will need to modify the pom.xml to use a later version of the spring-cloud parent. Try changing Brixton.RELEASEtoCamden.SR6.

Alternatively look at the maven dependency XML on the Spring Cloud project page: http://projects.spring.io/spring-cloud/

It takes a different approach, importing Spring Boot 1.4.5 as the parent and using Spring Cloud as a BOM (the dependencyManagement section).

Either way you will need to run Maven -> Update Project in Eclipse once you've updated the pom.xml.

Hi Paul, I didnt notice your reply.

But yes, I have modified the release as Camden.Release and it worked like a charm.

Thanks a ton.

Upgrading to Camden.RELEASE and updating the build.gradle as described in https://spring.io/blog/2016/09/26/spring-cloud-camden-release-and-brixton-sr6-are-available did the work for me. UPDATE: Even simpler in gradle.properties change pringBootVersion=1.4.0.RELEASE to springBootVersion=1.4.5.RELEASE

Have added note that gradle clean assemble can be used as an alternative to mvn clean package.
