SpringBoot without parent pom failsafe integration tests are failing

Question

I need to inherit from my organization's parent pom so I have following setup.

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

My main entrypoint class is in com.example.demo package.

Now I have an integration test in com.example.demo package as follows:

package com.example.demo;

import org.junit.Test;
import org.junit.runner.RunWith;
import org.springframework.boot.test.context.SpringBootTest;
import org.springframework.test.context.junit4.SpringRunner;

@RunWith(SpringRunner.class)
@SpringBootTest
public class DemoApplicationIT {

    @Test
    public void contextLoads() {
    }

}

When I run mvn clean install the integration test is failing with following error:

Tests run: 1, Failures: 0, Errors: 1, Skipped: 0, Time elapsed: 0.526 sec <<< FAILURE! - in com.example.demo.DemoApplicationIT
initializationError(com.example.demo.DemoApplicationIT)  Time elapsed: 0.008 sec  <<< ERROR!
java.lang.IllegalStateException: Unable to find a @SpringBootConfiguration, you need to use @ContextConfiguration or @SpringBootTest(classes=...) with your test

If I remove <goal>repackage</goal> from spring-boot-maven-plugin then it is working fine. But I need to run repackage goal to build fat jar.

Is there anyway to resolve this issue?

Answer 1

Apparently I hit this issue https://github.com/spring-projects/spring-boot/issues/6254

Fixed the issue by adding <classesDirectory> configuration as follows:

<plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-failsafe-plugin</artifactId>

    <configuration>
          <classesDirectory>${project.build.directory}/${artifactId}.jar.original</classesDirectory>
    </configuration>
</plugin>
