maven-plugin - 正确设置pitest-maven报告聚合目标

Question

伙计们!
我尝试在我的 Maven/Java 项目中使用 ptest-maven 插件，但它显然无法生成汇总报告(考虑到我有一个多模块项目)。
我从官方网站和其他几个来源收集了一些信息，但是，它们都没有真正有助于为这个场景定义正确的配置。
简而言之，我的结构如下所示:

父项目

child A

child B

child ...

child N

在某些子模块中，执行 pi-test 确实有意义，而其他子模块则没有。可以这么说，我的配置总体来说是。

父模块 pom:

                            <!--<reportsDirectory>${project.build.directory}/pit-reports</reportsDirectory>-->
                        </configuration>
                        <executions>
                            <execution>
                                <phase>test</phase>
                                <goals>
                                    <goal>mutationCoverage</goal>
                                </goals>
                            </execution>
                            <execution>
                                <id>report</id>
                                <phase>site</phase>
                                <goals>
                                    <goal>report-aggregate</goal>
                                </goals>
                            </execution>
                        </executions>
                    </plugin>
                </plugins>

                </plugin>
            </plugins>
        </build>
    </profile>

具有突变的子项目:

<plugins>
        <plugin>
            <groupId>org.pitest</groupId>
            <artifactId>pitest-maven</artifactId>
            <configuration>
                <mutationThreshold>80</mutationThreshold>
                <exportLineCoverage>true</exportLineCoverage>
            </configuration>
        </plugin>
    </plugins>

最后，当我尝试执行 相即使在我执行了创建文件的全新安装(如 linecoverage.xml 和 突变.xml ，我收到此错误:

[INFO] BUILD FAILURE

如果我做了错误的配置，或者是否有更好的方法来完成此设置的任何部分，你们中的任何人都知道吗？

Answer 1

您似乎同时遇到了几个问题:

运行时report-aggregate该插件分析它的模块的依赖关系
跑进来并期望他们每个人都有linecoverage.xml和 mutations.xml文件。您必须有一个专门用于报告聚合的子模块，并且应该运行 report-aggregate仅在此子模块中。

report-aggregate无法处理带时间戳的报告，必须禁用

我无法使用 site阶段。不确定这是插件中的错误还是我错过了某些东西(保持默认阶段有效，但您需要以某种方式获取报告，它不会在站点中)。

把它们放在一起:

在父模块 pom 中:

<build>
    <pluginManagement>
        <plugins>
            <plugin>
                <groupId>org.pitest</groupId>
                <artifactId>pitest-maven</artifactId>
                <version>1.3.2</version>
                <configuration>
                    <outputFormats>
                        <param>HTML</param>
                        <param>XML</param>
                    </outputFormats>
                    <!-- omitting mutators, testPlugin and verbose for brevity -->
                    <exportLineCoverage>true</exportLineCoverage>
                    <!--
                        it's currently not possible to aggregate timestamped
                        reports, so it must be disabled.
                     -->
                    <timestampedReports>false</timestampedReports>
                </configuration>
                <executions>
                    <execution>
                        <!--
                          Use an id to disable it in some submodules
                        -->
                        <id>pitest-mutation-coverage</id>
                        <phase>test</phase>
                        <goals>
                            <goal>mutationCoverage</goal>
                        </goals>
                    </execution>
                    <!--
                       NO report-aggregate here. Most of the time you don't
                       want it to run.
                    -->
                </executions>
            </plugin>
        </plugins>
    </pluginManagement>
    <!-- NO pitest here since its use will vary per submodule -->
</build>

在带有突变的子模块中 :

<plugins>
    <plugin>
        <groupId>org.pitest</groupId>
        <artifactId>pitest-maven</artifactId>
        <!--
           You can put configuration here, but IMOHO it's better to have it
           in the parent pom. (so I leave it out here)
         -->
    </plugin>
</plugins>

在生成报告的子模块中 :

<!--
   Only include submodules where `mutationCoverage` is run.
 -->
<dependencies>
    <dependency>
        <groupId>you.groupId</groupId>
        <artifactId>submodule-A</artifactId>
    </dependency>
    <dependency>
        <groupId>you.groupId</groupId>
        <artifactId>submodule-B</artifactId>
    </dependency>
</dependencies>

并且

<plugins>
    <plugin>
        <groupId>org.pitest</groupId>
        <artifactId>pitest-maven</artifactId>
        <executions>
            <!--
               Using the execution id to change its phase to none disables
               mutationCoverage in this module.
               (not sure it's the best way to do it, but as long as it doesn't
               run you should be fine)
            -->
            <execution>
                <id>pitest-mutation-coverage</id>
                <phase>none</phase>
            </execution>
            <execution>
                <id>report</id>
                <!--
                  Keep default phase here.
                -->
                <goals>
                    <goal>report-aggregate</goal>
                </goals>
            </execution>
        </executions>
    </plugin>
</plugins>
