java - 没有发现突变 PitTest Maven

Question

第一次尝试使用pitTest和maven，

使用 IntelliJ 理念。

对于以下 pom.xml 片段：

        <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：

带有以下错误消息：

Failed to execute goal org.pitest:pitest-maven:1.4.9:mutationCoverage (default-cli) on project Junit_Test: Execution default-cli of goal org.pitest:pitest-maven:1.4.9:mutationCoverage failed: No mutations found. This probably means there is an issue with either the supplied classpath or filters.

我努力了：

-> 添加 targetClasses 和 targetTests 配置参数（堆栈跟踪中源目录中的参数）

-> 添加 .* 作为 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 测试类的 .java 文件位于 project_dir/src/test/java
