JUnit test with Maven in a Jenkins plugin

Question

I have a problem when I tried to run JUnit tests with Maven. For a Jenkins plug-in I wrote a class for test. For example: I have the class ConsoleParser in package com.jenkins_plugin in folder src/main/java. The JUnit test case is ConsoleParserTest in package com.jenkins_plugin in folder src/test. For running the JUnit test I added the dependency in the pom:

<dependencies>
    <dependency>
        <groupId>junit</groupId>
        <artifactId>junit</artifactId>
        <version>4.11</version> 
        </dependency>
</dependencies>

And I ran in cmd the next command: mvn -Dtest=ConsoleParserTest test

The problem is that I've got the following error:

[ERROR] Failed to execute goal org.apache.maven.plugins:maven-surefire-plugin:2.
12:test (default-test) on project swatt_jenkins: No tests were executed!  (Set -
DfailIfNoTests=false to ignore this error.) -> [Help 1]

The full pom.xml is:

Also, I must mention that with those settings I ran successfully the test but after adding findbugs it crashed. So, I removed findbugs and try to run the test again but the problem that I mentioned appeared. So, can someone explain what I have to do? I tried to add another version of JUnit, Surefire but I had the same problem and I don't understand why.

Solution

Several things:

• add you JUnit classes to src/test/java not src/test
• for your JUnit class use the scope "test"

E.g.:

<dependency>
    <groupId>junit</groupId>
    <artifactId>junit</artifactId>
    <version>4.11</version> 
    <scope>test</scope>
</dependency>

Also I recommend to manage your repositories in a repository manager such as Nexus, not in your POM:
