Question

I want to use spring boot to start my application ,but after i add some relative jar at pom.xml,it return this error:and i thank may be it caused by some conflict jars?

Answer 1

As explained by Andy Wilkinson in this GitHub issue or in this thread, these obscure exceptions occur when some annotation is referencing a class that isn't on the classpath.

Most issues of this kind have been fixed in recent Spring Boot versions, but you can also trigger one from your code, for example when using @AutoConfigureAfter(X.class) where class X is missing on the classpath.
