Maven Failsafe plugin - SurefireBooterForkException: There was an error in the forked process (TypeNotPresentExceptionProxy)

问题

I get this strange stacktrace when running mvn clean verify -P P1

[ERROR] Failed to execute goal org.apache.maven.plugins:maven-failsafe-plugin:2.21.0:verify (default) on project prj-name: There are test failures.

What does it mean?

UPDATE

There's a surefire dumpstream file

Because of garbage in string variables and occasional IndexOutOfBoundsException / ConcurrentModificationException in logs it seems like a concurrency issue.

This GitHub issue - [#6254] Maven-failsafe-plugin fails to execute integration tests - and the related discussion helped me to solve my problem.

It's a bug. It turns out that newer Failsafe plugin versions (2.19.0 and later) don't work well with Spring Boot 1.4 (or later). Workaround is to downgrade the maven-failsafe-plugin to 2.18.1. Here's the updated pom.xml:

<plugins>
    <plugin>
        <groupId>org.apache.maven.plugins</groupId>
        <artifactId>maven-failsafe-plugin</artifactId>
        <!-- I don't specify version at all (Spring Boot can autoconfigure plugin version) -->
        <executions>
            <execution>
                <!-- changed <id> to <phase>, but I don't know whether it's important or not. -->
                <phase>integration-test</phase>
                <!-- ... no changes here: the same as in the question ... -->
            </execution>
        </executions>
    </plugin>
</plugins>

回答2:

I followed the solution proposed here: https://github.com/spring-projects/spring-boot/issues/6254#issuecomment-307151464

Currently, I have failsafe plugin 2.22.0 and I'm able to use this version and not downgrade by explicitly configuring the classesDirectory property:

<classesDirectory>${project.build.outputDirectory}</classesDirectory>

Example:

<plugin>
  <groupId>org.apache.maven.plugins</groupId>
  <artifactId>maven-failsafe-plugin</artifactId>
  <version>2.22.0</version>
  <configuration>  
     ...                 
     <classesDirectory>${project.build.outputDirectory}</classesDirectory>
     ...
  </configuration>
  <executions>
     <execution>
        <goals>
           <goal>integration-test</goal>
           <goal>verify</goal>
        </goals>
     </execution>
  </executions>
</plugin>

Another variant of the workaround is described later in the same Github issue thread: https://github.com/spring-projects/spring-boot/issues/6254#issuecomment-343470070

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

Note (2020-02-27): maven-failsafe-plugin version 3.0.0-M4 still needs these workarounds :-(
