How to resolve this conflicting of two beans with same name in maven project?

Question

Suppose i have a Maven Project A and Project B, and project B i am adding it as as a jar in Project A when i try to run Project A it gives me the error "bean name "xyz" conflicts with existing, non-compatible bean definition of same name and class"

So anyone has solution to this to ignore the bean "xyz" of Project B and run only "xyz" bean of Project A or is there any annotation or something like that?

Having that situation is kind of a code-smell. Perhaps it is time to look into refactoring? — Niels Bech Nielsen

Using @Lazy on bean "xyz" of Project B could be an approach? — Phat H. VU

Use the @Primary annotation on the bean defenition on the configuration class

@Bean(name = "beanOnA") @Primary public YourInterface yourBeanOnProjectA(){ return new YourClass("Bean on Project A"); }

While autowiring the bean specify the bean name using qualifier annotation.

@Autowired @Qualifier("beanOnA") YourInterface yourInterface;

You can use Qualifier annotation to achieve this.

@Qualifier("ProjectA") or @Qualifier("complete.package.ProjectA")

This only helps if you are able to edit the code. What if it is external dependensies
