Question

我使用在我的POM中配置的allure-maven插件。但是，当它失败时

ru.yandex.qatools.allure.data.ReportGenerationException: Could not find any allure results

我想在运行时调试插件，看看它是否正确设置了所有变量。

我根据Debugging in Maven?的答案尝试使用mvnDebug。当Maven使用surefire插件执行测试时，我能够将调试器连接到JVM。但是，当Maven尝试用allure插件生成Allure报告时，我无法连接调试器。 Allure插件在POM的“报告”部分中定义，并由“站点”Maven目标使用。

这是我用mvn clean test site命令调用的POM（几乎完成，我省略了依赖项部分）。

Answer 1

如果使用“mvnDebug clean install”而不是“mvn clean install”开始构建，Maven将等待远程调试器在端口8000上进行连接。这应适用于不在自己的JVM中运行的所有插件。

这需要Maven更大> 2.0.8我假设你正在运行。

请参阅Debugging in Maven?

Answer 2

而不是allure-maven插件调试，您可能希望首先修复配置问题。你已经将插件放入了错误的pom部分。请参阅官方插件的docs。

Allure 2不再使用报告部分。您应该将插件插入构建部分。

报告生成命令也会更新。您应该使用以下内容代替site目标调用：

mvn allure:report
mvn allure:serve

检查this示例以了解有效配置。

Answer 3

如果要从Intellij IDEA调试它。我假设您运行捆绑的mvn，JDK9 +

转到IDEA中的Maven Runner设置。
在“ VM选项”中指定以下行：-agentlib:jdwp=transport=dt_socket,address=5005,server=y,suspend=y

直到您与Maven建立联系，Maven才会继续进行远程调试器。

创建远程调试器配置（指定端口5005）。
运行远程调试器（不要忘记在代码中添加断点）。

如何调试Maven插件？
