java.lang.NoClassDefFoundError: org/springframework/core/io/ResourceLoader

Question

I am using spring for some testing, and I am getting this error:

java.lang.NoClassDefFoundError: org/springframework/core/io/ResourceLoader  at org.springframewo         


        

Answer 1

As per Amir's answer the jar you need is spring-core. You can generally solve this sort of issue by consulting jarfinder http://www.jarfinder.com/index.php/java/search/~org.springframework.core.io.ResourceLoader~

Answer 2

I strongly advice using Maven (or Ivy or Gradle) for dependency management. It can save you loads of pain in resolving these types of secondary and tertiary dependencies.

Answer 3

You also need spring-core-*.jar. You can usually tell what jars you are missing by looking at the package. In this org.springframework.core.* is all in the core jar file.
