tomcat 7 embedded doesn't shutdown correctly ClassNotFoundException ContainerBase$StopChild

Question

I'm trying to make work integration test with Tomcat7 embedded plugin with this config:

            <plugin>
                <groupId>org.apache.tomcat.maven</groupId>
                <artifactId>tomcat7-maven-plugin</artifactId>

                    <systemProperties>
                        <logback.configurationFile>${project.build.testOutputDirectory}/logback-test.xml</logback.configurationFile>
                        <psw.config>${project.build.testOutputDirectory}</psw.config>
                        <spring.profiles.active>test-e2e</spring.profiles.active>
                    </systemProperties>
                </configuration>
                <dependencies>

                        <goals>
                            <goal>run-war-only</goal>
                        </goals>
                        <configuration>
                            <fork>true</fork>
                        </configuration>
                    </execution>
                    <execution>
                        <id>stop-tomcat</id>

                        <goals>
                            <goal>shutdown</goal>
                        </goals>
                    </execution>
                </executions>
            </plugin>

However when the shutdown happens, I kept having this error: Caused by: java.lang.ClassNotFoundException: org.apache.catalina.core.ContainerBase$StopChild

Any tips to correct this ?

If you run mvn integration-test, it won't run the post-integration-test phase, which can lead to this error. Use mvn verify instead.
