I have a Java8/Maven/Spring Boot project involving the maven-failsafe-plugin (in order to run integration tests in *IT.java, separately from unit tests in *Test.java) and cobertura-maven-plugin.

The issue is that mvn clean site fails to conclude if an integration test fails, while mvn clean site is fine if an unit test fails.

To reproduce this, I first added a src/test/java/app/FailingTest.java containing:

package app;

import org.junit.Test;

import static org.junit.Assert.fail;

public class FailingTest 

 @Test
 public void failingTest () 
 fail();
 

and mvn clean site yields:

...
[INFO] -------------------------------------------------------
[INFO] T E S T S
[INFO] -------------------------------------------------------
[INFO] Running app.FailingTest
[ERROR] Tests run: 1, Failures: 1, Errors: 0, Skipped: 0, Time elapsed: 0.063 s <<< FAILURE! - in app.FailingTest

java.lang.AssertionError
 at app.FailingTest.failingTest(FailingTest.java:11)
...
[INFO] Cobertura Report generation was successful.
[INFO] ------------------------------------------------------------------------
[INFO] BUILD SUCCESS
[INFO] ------------------------------------------------------------------------

Then I renamed that class to src/test/java/app/FailingIT.java, and mvn clean site yields:

...
[INFO] -------------------------------------------------------
[INFO] T E S T S
[INFO] -------------------------------------------------------
[INFO] Running app.FailingIT

...
[INFO] --- maven-failsafe-plugin:2.22.1:verify (default) @ example-project ---

[INFO] BUILD FAILURE

How can one fix this?

My pom.xml is as follows:

It's the maven-failsafe-plugin that's responsible for the build failure. The reason is clearly called out in your pom.xml as :

<goal>integration-test</goal>

If the test is really an Integration Test (IT), you must fix it or else if it is not an integration test, you can rename it to be categorized as a Unit Test(UT) but still fix it :)

Another poor way of getting rid of this error could be commenting out the failsafe plugin declaration all together in the pom.xml making it inactive. I would suggest to refrain from doing so though.
