Arquillian - ClassNotFound on org.jboss.arquillian.core.api.threading.ExecutorService

Question

I'm currently trying to make arquillian works but I have a problem on one of my Unit Test. It fails on a CLassNotFoundException on class org.jboss.arquillian.core.api.threading.ExecutorService. Maybe I forgot a dependancy in my pom.xml, or I misunderstood something but I cannot solve this issue.

Here is the stacktrace :

Why do I have a ClassNotFoundException on org.jboss.arquillian.core.api.threading.ExecutorService ? Any idea where the problem is ?

Answer 1

Try adding

<dependency>
        <groupId>org.jboss.arquillian.core</groupId>
        <artifactId>arquillian-core-api</artifactId>
        <version>1.1.4.Final</version>
        <scope>test</scope>
</dependency>

Answer 2

There is an older version of arquillian-core-api probably in your classloader to causes this.

Try to use arquillian-bom to manage correct version of all arquillian dependencies like this:

<dependencyManagement>
   <dependencies>
     <dependency>
        <groupId>org.jboss.arquillian</groupId>
        <artifactId>arquillian-bom</artifactId>
        <version>1.1.4.Final</version>
        <scope>import</scope>
        <type>pom</type>
    </dependency>
   </dependencies>
</dependencyManagement>

I pasted the above code from http://arquillian.org/guides/getting_started/#add_the_arquillian_apis
