[cosyman]

Question

I want to use spring-cloud-sleuth(Finchley.RC1) without ribbon and hystrix。so I exclude this dependency, but sleuth bean config with problem

 configurations {
        all.collect { configuration ->
            configuration.exclude group: 'org.springframework.cloud', module: 'spring-cloud-netflix-ribbon'
            configuration.exclude group: 'org.springframework.cloud', module: 'spring-cloud-netflix-archaius'
            configuration.exclude group: 'org.springframework.cloud', module: 'spring-cloud-starter-netflix-ribbon'
            configuration.exclude group: 'org.springframework.cloud', module: 'spring-cloud-starter-netflix-archaius'
            configuration.exclude group: 'io.github.openfeign', module: 'feign-hystrix'
        }
    }

and with follow exception

org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'traceFeignObjectWrapper' defined in class path resource [org/springframework/cloud/sleuth/instrument/web/client/feign/TraceFeignClientAutoConfiguration.class]: Post-processing of merged bean definition failed; nested exception is java.lang.IllegalStateException: Failed to introspect Class [org.springframework.cloud.sleuth.instrument.web.client.feign.TraceFeignObjectWrapper] from ClassLoader [sun.misc.Launcher$AppClassLoader@2a139a55]

[marcingrzejszczak]

Can you verify with the latest snapshots if things are working well?

[cosyman]

@marcingrzejszczak I try spring cloud with version Finchley.BUILD-SNAPSHOT,and the same error happened. I run in debug mode, TraceFeignObjectWrapper.wrap method seems work right. Application not Enter the breakpoint in clientFactory() method. and bootRun failed
