What's causing this Maven/JBehave error?

StackOverflow https://stackoverflow.com/questions/19040667

Question

I have a Maven project that produces a Mule Connector. It's basically a shell, so I started adding some BDD tests using JBehave. The first test I added does very little:

public class FakeSteps extends Embedder {

    @Given("I have something")
    public void iHaveSomething() {        
        System.out.println("Have something...");
    }

    @When("I do something")
    public void iDoSomething() {
        System.out.println("Doing something...");
    }

    @Then("we are ok")
    public void weAreOk() {
        Assert.assertTrue("FAILURE!!!!!", true);
        System.out.println("We are ok.");
    }
}

If I run the test in IntelliJ it passes. When I perform a "mvn clean install", the test does not throw an error but the build fails due to an exception in "org.apache.log4j.Priority":

...

Have something...
Doing something...
We are ok.

My Maven, Java, and machine information is:

It's unclear to me what the root cause is. I added log4j as a Maven dependency and the problem continues.

Any thoughts on what the root problem is or how to fix it?

--- Update ---

As per the conversation below I added the dependency to log4j in my JBehave plugin, and the problem was fixed:

<plugin>
   <groupId>org.jbehave</groupId>
   <artifactId>jbehave-maven-plugin</artifactId>
   <version>${jbehave.version}</version>
   <executions>
      <execution>...</execution>
   </executions>
   <dependencies>
      <dependency>
         <groupId>log4j</groupId>
         <artifactId>log4j</artifactId>
         <version>1.2.17</version>
         <scope>compile</scope>
      </dependency>
   </dependencies>
</plugin>
Was it helpful?

Solution

I think one of you dependencies implicitly uses previous version of log4j which does not include org.apache.log4j.Priority. Run mvn dependency:tree -Dverbose to see the dependency tree and then exclude old log4j version.

Update: According to the given tree, your log4j dependency has a provided scope: log4j:log4j:jar:1.2.16:provided, which means it won't be included into classpath during maven test phase. You may want to explicitly mention log4j artifact in your pom with the test scope.

According to author comments, explicit log4j plugin dependency has fixed the problem.
