我正在尝试为我开发的一个简单的 Maven 插件生成代码覆盖率报告。Cobertura 在我的项目中正确生成了包含三个类的报告，但即使测试成功执行，它也会报告 0% 的代码覆盖率。我已经在调试模式下运行它，Cobertura 没有报告任何错误或堆栈跟踪。

我在 POM 文件中的配置非常简单：

</build>

Cobertura 适用于我的所有其他项目（到目前为止），是否有任何理由无法报告 Maven 插件项目的覆盖率？

看来问题出在我的万无一失的配置上。我把它改成

        <plugin>
            <artifactId>maven-surefire-plugin</artifactId>
            <version>2.16</version>
            <executions>
                <execution>
                    <id>test-custom-plugin</id>
                    <phase>test</phase>
                    <goals> 
                        <goal>test</goal>
                    </goals>
                    <configuration>
                        <forkCount>1</forkCount>
                        <reuseForks>true</reuseForks>
                    </configuration>
                </execution>
            </executions>
        </plugin>

现在可以正确生成报告。我从一些我看到的与为声纳插件生成报告相关的类似问题的帖子中得到了更改 fork 选项的想法，并且更改了 fork 选项解决了这个问题。
