【问题描述】：
我正在尝试在 light4j (https://github.com/networknt/light-4j) 的主版本上运行 PITest，这是我或多或少随机选择的一个项目，用于在真实世界代码上试用 PITest。
除了 light4j 的“cient”模块外，大多数模块的测试都可以正常完成。运行时
mvn -X test org.pitest:pitest-maven:mutationCoverage
在 light-4j/client 文件夹中，正常的单元测试运行完成（所有测试都正常，跳过了 3 个），但 PITest 似乎没有生成和执行突变。最后的消息是
[INFO] Adding org.pitest:pitest to SUT classpath
[INFO] Mutating from /Users/jan/dev/inno/light-4j/client/target/classes
[INFO] Defaulting target classes to match packages in build directory
/-\|/-\|/-\|/-\|/-stderr : WARNING: An illegal reflective access operation has occurred
WARNING: Illegal reflective access by org.xnio.nio.NioXnio$2 (file:/Users/jan/.m2/repository/org/jboss/xnio/xnio-nio/3.3.8.Final/xnio-nio-3.3.8.Final.jar) to constructor sun.nio.ch.KQueueSelectorstderr : Provider()
WARNING: Please consider reporting this to the maintainers of org.xnio.nio.NioXnio$2
WARNING: Use --illegal-access=warn to enable warnings of further illegal reflective access operations
WARNING: All illegal access operations will be denied in astderr : future release
之后什么都没有发生。
light4j 的正常构建成功完成。
可能是什么问题？
[2020 年 2 月 5 日编辑：
我已经分叉了 light4j 存储库：https://github.com/jvermeir/light-4j
然后我执行了一个正常的构建mvn clean install，所以所有的工件都在我的本地 maven 存储库中。
接下来我在light4j项目的根级别更改了pom.xml，添加了
<plugin>
<groupId>org.pitest</groupId>
<artifactId>pitest-maven</artifactId>
<version>1.4.10</version>
<dependencies>
<!-- <dependency>-->
<!-- <groupId>org.pitest</groupId>-->
<!-- <artifactId>pitest-junit5-plugin</artifactId>-->
<!-- <version>0.10</version>-->
<!-- </dependency>-->
</dependencies>
</plugin>
在构建部分
最后，我在客户端文件夹启用 PiTest 的情况下执行了测试：mvn -X test org.pitest:pitest-maven:mutationCoverage > ../buildlog.txt
这会生成一个 build.txt 文件，但也会在终端中显示几行：

build.txt 的结尾是这样的：
