为什么Jacoco合并不包括文件？

Question

我有一个多模块的maven项目，并试图使用Jacoco生成聚合报告，并运行“聚合”检查。但是，我无法以任何可能的方式使Jacoco合并功能通过maven插件工作。因此，我试图创建一个最小的示例，如下所示

我尝试下载jacococli.jar并手动合并文件，这很好。我想这可以用maven ant run插件下载并运行作为解决方案，但我更喜欢只使用插件！

有什么想法会导致这个问题吗？

Answer 1

您的

<fileSet>
  <directory>${basedir}/}</directory>

看起来可疑-注意尾随的花括号，它可能被解释为目录名。
