问题描述
第一次尝试使用pitTest和maven，
使用IntelliJ Idea。
对于以下pom.xml代码段：
<plugins>
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-surefire-plugin</artifactId>
<version>2.22.1</version>
</plugin>
<plugin>
<groupId>org.pitest</groupId>
<artifactId>pitest-maven</artifactId>
<version>1.4.9</version>
<configuration>
<verbose>true</verbose>
</configuration>
<dependencies>
<dependency>
<groupId>org.pitest</groupId>
<artifactId>pitest-junit5-plugin</artifactId>
<version>0.12</version>
</dependency>
</dependencies>
</plugin>
</plugins>
我得到以下堆栈跟踪：

我尝试过：
->将。*添加为targetClasses和targetTests
两者都给出相同的错误。
类的.java文件位于project_dir / src / main / java中 测试类的.java文件位于project_dir / src / test / java
中解决方法
暂无找到可以解决该程序问题的有效方法，小编努力寻找整理中！
