jacoco插件配置单测覆盖率计算排除某个类

要在使用Jacoco插件时排除某个类的单元测试覆盖率计算，你可以在`<build>`标签内添加以下代码：

<plugins>
  <plugin>
    <groupId>org.jacoco</groupId>
    <artifactId>jacoco-maven-plugin</artifactId>
    <version>${jacoco.version}</version>
    <executions>
      <execution>
        <id>default-prepare-agent</id>
        <goals>
          <goal>prepare-agent</goal>
        </goals>
        <configuration>
          <excludes>
            <exclude>com/example/MyClass.java</exclude>
          </excludes>
        </configuration>
      </execution>
      <execution>
        <id>default-report</id>
        <goals>
          <goal>report</goal>
        </goals>
        <configuration>
          <excludes>
            <exclude>com/example/MyClass.java</exclude>
          </excludes>
        </configuration>
      </execution>
    </executions>
  </plugin>
</plugins>

其中，`<excludes>`标签内的内容为要排除的类的路径。例如，要排除`com.example.MyClass`类，就将`<exclude>`标签内的内容设置为`com/example/MyClass.java`。
