Could not find class [org.springframework.boot.autoconfigure.condition.OnBeanCondition]

Question

Im using feign client to make rest calls between microservices, When i execute it using IntelliJ IDEA its working fine. But if i execute it with jar it gives me following error.

org.springframework.beans.factory.BeanDefinitionStoreException: Failed to parse configuration class [org.springframework.cloud.netflix.eureka.loadbalancer.EurekaLoadBalancerClientConfiguration]; nested exception is java.lang.IllegalArgumentException: Could not find class [org.springframework.boot.autoconfigure.condition.OnBeanCondition]

We currently experience the same thing and are trying to resolve it.. — Tom, Jul 20 '22 at 08:30

We had the same issue. After a research we found out that the issue is similar to described in the feign client bug.

The temporary fix provided by DenisKorolev resolves the issue by setting correct ClassLoader during context initialisation.

    @Bean
    @ConditionalOnMissingBean
    public LoadBalancerClientFactory loadBalancerClientFactory(LoadBalancerClientsProperties properties) {
        return new LoadBalancerClientFactory(properties) {
            @Override
            protected AnnotationConfigApplicationContext createContext(String name) {
                // FIXME: temporary switch classloader to use the correct one when creating the context
                ClassLoader originalClassLoader = Thread.currentThread().getContextClassLoader();
                Thread.currentThread().setContextClassLoader(this.getClass().getClassLoader());
                AnnotationConfigApplicationContext context = super.createContext(name);
                Thread.currentThread().setContextClassLoader(originalClassLoader);
                return context;
            }
        };
    }
