Instead of:

                <executions>
                    <execution>
                        <phase>test-compile</phase>
                        <goals>
                            <goal>operation</goal>
                        </goals>
                    </execution>
                </executions>

Should be:

                <executions>
                    <execution>
                        <id>test-compile</id>
                        <phase>test-compile</phase>
                        <goals>
                            <goal>operation</goal>
                        </goals>
                    </execution>
                    <execution>
                        <!-- Runs before integration tests and jetty:run-war -->
                        <id>test</id>
                        <phase>test</phase>
                        <goals>
                            <goal>operation</goal>
                        </goals>
                    </execution>
                </executions>
