maven-2 - maven cobertura 报告 0% 与 aspectj

Question

有人能够将 maven2 与 Aspectj 插件和 Cobertura 插件一起使用吗？当我应该得到一些东西时，我一直得到 0% 的覆盖率。 Cobertura 检测在 Aspectj 编织之前运行，我认为这会扰乱 Cobertura 检测。此外，Cobertura 正在就我的方面发出警告，看起来它正试图将它们解析为 java 文件。任何帮助将不胜感激。

我的项目使用 aspectj-maven-plugin 进行编译，并使用 cobertura-maven-plugin 进行代码覆盖。对于编译时编织，这在运行 mvn site 时工作正常，尽管测试被编译/运行两次以允许 Cobertura 编织。

使用以下配置运行 mvn site 会产生以下输出:

我的配置包含在下面。

关于您方面的 Cobertura 警告，您可以尝试的一件事是将建议执行主体移动到 java 类型，而不是在方面中定义它。

例如，而不是这样做:

before(Throwable e, Object subject): handlers(e, subject) {
    Log logger = getTraceLog(subject.getClass());

    //code to trace exception handling
    ...
}

相反，您可以将实现委托(delegate)给 Java 类型，因此要处理的方面中的代码很少:

before(Throwable e, Object subject): handlers(e, subject) {
    Log logger = getTraceLog(subject.getClass());

    //get helper type and delegate processing to that type.
    getFormatterHelper().traceErrorHandling(logger, thisJoinPoint, e);
}

我对 aspectj 和 cobertura 插件的配置:
