I am trying to include my test classes in a generated JAR in a Maven Project.

I have created the Maven project and created the test classes with JUnit.

When I am trying to build the JAR, these test classes are not included in the generated JAR.

  • testclasses should not be part of the jar. – Jens Apr 09 '18 at 09:15

    You can package test classes as a separate `test-jar`, see here: https://stackoverflow.com/questions/7751860/how-do-i-include-a-dependencys-test-jar-into-a-maven-projects-deployment – lexicore Apr 09 '18 at 09:17
  • A jar is allowed to have only source code, resources, configuration and manifest files. – Manmohan_singh Apr 09 '18 at 09:45
  • I've slightly improved the grammar and removed the maven-plugin tag, as the documentation for that tag says to only use it for questions relating to the development of Maven plugins. – DaveyDaveDave Apr 09 '18 at 20:46
  • The requirement is to run test classes in Jmeeter. We need a Jar file with test classes as well. We got the solution with assembly file. – Ravikiran S Apr 12 '18 at 09:41

You can produce a jar which will include your test classes and resources. Please refer maven official site - https://maven.apache.org/plugins/maven-jar-plugin/examples/create-test-jar.html

<project>
  ...
  <build>
    <plugins>
      ...
      <plugin>
        <groupId>org.apache.maven.plugins</groupId>
        <artifactId>maven-jar-plugin</artifactId>
        <version>3.0.2</version>
        <executions>
          <execution>
            <goals>
              <goal>test-jar</goal>
            </goals>
          </execution>
        </executions>
      </plugin>
      ...
    </plugins>
  </build>
  ...
</project>

I have resolved issue be adding things. We will get two jars. One with classes and other with test classes.

assembly.xml

<?xml version="1.0" encoding="UTF-8"?>
