The current stable version (2.2) of the maven-surefire-plugin does not support JUnit 4. So Maven, out of the box, does not work with JUnit 4. Luckily if we want to use JUnit 4 in our Maven based projects we have two choices. The first is to use
JUnit4TestAdapter as illustrated in this post. The second is to use the snapshot version (2.3-SNAPSHOT) of the maven-surefire-plugin that has support for JUnit 4. In a small pet-project I am currently implementing I chose the second option and so far my experience was without any problems.
To use the 2.3-SNAPSHOT you first have to add the Maven snapshot plugin repository into your list of plugin repositories. In your pom.xml add the below XML:
<pluginRepositories> <pluginRepository> <id>apache.org</id> <name>Maven Plugin Snapshots</name> <url>http://people.apache.org/repo/m2-snapshot-repository</url> <releases> <enabled>false</enabled> </releases> <snapshots> <enabled>true</enabled> </snapshots> </pluginRepository> </pluginRepositories>
You can also put this configuration into your ~/.m2/settings.xml file to enable this repository for all your projects.
Then go to the maven-surefire-plugin configuration section and change the version from 2.2 to 2.3-SNAPSHOT. For example below I have the maven-surefire-plugin configuration that I use in my pet-project:
<plugin> <groupId>org.apache.maven.plugins</groupId> <artifactId>maven-surefire-plugin</artifactId> <version>2.3-SNAPSHOT</version> <configuration> <includes> <include>**/*Test.java</include> </includes> <forkMode>once</forkMode> </configuration> </plugin>
That’s it, you are done. When you run Maven again the new (2.3-SNAPSHOT) version will be downloaded and you can start using JUnit 4 in you project.
