Maven 3 and JUnit 4 compilation problem: package org.junit does not exist


I am trying to build a simple Java project with Maven. In my pom-file I declare JUnit 4.8.2 as the only dependency. Still Maven insists on using JUnit version 3.8.1. How do I fix it?

The problem manifests itself in a compilation failure: "package org.junit does not exist". This is because of the import statement in my source code. The correct package name in JUnit 4.* is org.junit.* while in version 3.* it is junit.framework.*

I think I have found documentation on the root of the problem on http://maven.apache.org/plugins/maven-surefire-plugin/examples/junit.html but the advice there seems to be meant for Maven experts. I did not understand what to do.


Solution

  • @Dennis Roberts: You were absolutely right: My test class was located in src/main/java. Also the value of the "scope" element in the POM for JUnit was "test", although that is how it is supposed to be. The problem was that I had been sloppy when creating the test class in Eclipse, resulting in it being created in src/main/java insted of src/test/java. This became easier to see in Eclipse's Project Explorer view after running "mvn eclipse:eclipse", but your comment was what made me see it first. Thanks.
