Spring annotation configuration java.lang.NoClassDefFoundError: org/objectweb/asm/util/TraceClassVisitor

Question

i am trying to run a very simple Spring application with java configuration. i am getting the following exception and i dont understand why. as far as i can tell i have all the required dependencies

public static void main(String[] args) 
{
     System.out.println( "Hello World from main!" );
     ApplicationContext ctx = new AnnotationConfigApplicationContext(AppConfig.class);
     HelloWorld helloWorld = ctx.getBean(HelloWorld.class);
     System.out.println( helloWorld.getMessage() );
}

The exception occures at - AnnotationConfigApplicationContext function call

worth mentioning: I have the following dependency in my POM.XML file.

  <dependency>
        <groupId>org.springframework</groupId>
        <artifactId>spring-asm</artifactId>
        <version>${org.springframework.version}</version>
    </dependency>

And the exception:

Exception in thread "main" java.lang.IllegalStateException: Cannot load configuration class: spring.play.springStart.AppConfig

Answer 1

I actually don't really know what solved the problem, but I did go to some tutorial website that does the same thing and just copied their pom file dependencies. I still don't understand what was missing.

In any case Balint Bako might be right with his answer but i am not sure, i got it solved by the time I got back to StackOverflow.

Here is the pom file

  <!-- Spring 3 dependencies -->
    <dependency>
        <groupId>org.springframework</groupId>
        <artifactId>spring-core</artifactId>
        <version>${spring.version}</version>
    </dependency>
    <dependency>
        <groupId>org.springframework</groupId>
        <artifactId>spring-context</artifactId>
        <version>${spring.version}</version>
    </dependency>
    <!-- JavaConfig need this library -->
    <dependency>
        <groupId>cglib</groupId>
        <artifactId>cglib</artifactId>
        <version>2.2.2</version>
    </dependency>

Good luck
