Apache Tika 项目有一个根目录，其中有一个 pom.xml。在根目录中有名为"Tika-Parent"的子模块和模块。在父模块中还有一个pom.xml文件。
现在我正在将 jacoco Maven 插件添加到 Tika 以获得代码覆盖率，但我遇到了问题，因为当我将 Jacoco Maven 插件添加到根目录中的 Pom.xml 时。它成功构建，但给出错误："由于缺少执行数据文件而跳过 JaCoCo 执行：C：\Users\adity\IdeaProjects\tika-1.20\target\jacoco.exec">
我尝试将JaCOCO插件一起添加到pom.xml文件中，也可以逐个添加，但没有结果。
此外，当我在 pom 上执行 Maven 测试时.xml在根目录中，它会成功构建运行所有测试。
但是当我在 Tika 父级的 pom 上执行 Maven 测试时.xml它不会运行任何测试，但构建成功。
我在根目录中的Pom.xml以及根目录中的Tika父模块中的pom.xml下面附加。
我正在使用IntelliJ社区版(网站上的最新版本)。 Java 版本 - JDK 8 ， Maven 版本 3。
详细信息来自根目录pom.xml

Jacoco插件也存在于这个pom文件中，这与早期的pom文件相同。
我尝试放入此文件并构建它。没用。他尝试将jacoco插件放在根pom文件中，但没有工作。 给出与上述相同的提及错误。
请帮忙！！
在我的代码中，我将 jacoco 插件插入插件管理标签下的根 pom 中：
<pluginManagement>
<plugins>
<plugin>
<groupId>org.jacoco</groupId>
<artifactId>jacoco-maven-plugin</artifactId>
<version>0.7.9</version>
<executions>
<execution>
<id>default-prepare-agent</id>
<goals>
<goal>prepare-agent</goal>
</goals>
</execution>
<execution>
<id>default-report</id>
<phase>prepare-package</phase>
<goals>
<goal>report</goal>
</goals>
</execution>
</executions>
</plugin>
</plugins>
</pluginManagement>
在我进行单元测试的每个子模块中，我插入以下pom.xml配置：
<build>
<plugins>
<plugin>
<groupId>org.jacoco</groupId>
<artifactId>jacoco-maven-plugin</artifactId>
</plugin>
</plugins>
</build>
您必须仅在有单元测试的 java 模块中启用 jacoco 插件。
