Maven: NoClassDefFoundError: org.springframework.test.context.junit4.SpringJUnit4ClassRunner

Tags:

spring-test

I have a classpath issue.

  • Background: Building and running a Spring WebApp.
  • Originally it was one big project including dao/service/controller/webapp.
  • I have just broken my project into a maven module project essentially splitting the webapp from the dao and service layers.
  • Now my webapp junit tests do not run.
  • The junit code has not changed and I don't think the dependencies have changed (albeit shifted around).
  • Spring-test is in my local repository.
  • Spring-test is in my unit test runtime classpath (used mvn debug logging to check)
  • I have no other classpath issues. All dao module tests run fine

However, I get 

java.lang.NoClassDefFoundError: Could not initialize class
org.springframework.test.context.junit4.SpringJUnit4ClassRunner.

I will post my parent and child pom.xml. If anyone has a suggestion, I'd be very grateful.

I dont know why but in my case spring-boot-starter-test comes with junit 4.10 and I find that is compiled with 4.12, so after add

 <dependency> 
        <groupId>junit</groupId>
        <artifactId>junit</artifactId>
        <version>4.12</version> 
</dependency>

Works fine. Maybe a misconfiguration in pom of spring-boot

In a comment you've said that project compiles, but tests don't run. Maven-surefire-plugin may be the culpit (as it was in my case). I was getting the same error, but after a little digging I knew that:

java.lang.NoClassDefFoundError: Could not initialize class
org.springframework.test.context.junit4.SpringJUnit4ClassRunner.

was caused by:

java.lang.IllegalStateException: SpringJUnit4ClassRunner requires JUnit 4.12 or higher.
    at org.springframework.test.context.junit4.SpringJUnit4ClassRunner.<clinit>

which was thrown because maven-surefire-plugin wasn't picking test framework provider from the classpath but instead supplied its own outdated junit provider.

I get rid of the error by specifying JUnit artifact name:

<plugins>
...
    <plugin>
        <groupId>org.apache.maven.plugins</groupId>
        <artifactId>maven-surefire-plugin</artifactId>
        <version>{your.surefire.version}</version>
        <configuration>
            <junitArtifactName> junit:junit:{your.junit.version} </junitArtifactName>
        </configuration>
    </plugin>
...
</plugins>
