我们在GitLab上有一个自动化项目，该项目使用我们专用的“外壳” GitLab运行器。项目本身是一个Selenium项目，它运行Cucumbers测试并生成报告。它最近在Jenkins上运行，没有任何问题。为了模拟Jenkins环境，我创建了一个外壳的GitLab运行程序，该运行程序在具有相同版本的计算机上安装了Java，Maven等。在线挖掘大量资源。从我的“主机”文件一直修改了所有内容。但是没有设法解决这个问题。
测试运行正常并生成报告。但是“生成报告部分”是不一致的。这意味着有时它无法生成Cucumber报告。这两天工作正常，第二天撞墙。
pom文件部分：
<groupId>org.codehaus.mojo</groupId>
<artifactId>exec-maven-plugin</artifactId>
<version>1.6.0</version>
问题不是测试的执行，它们总是成功的。之后发生问题。Cucumber无法在很少的构建中一次生成报告，即使在代码方面和基础架构方面都没有改变。
这是测试成功后得到的错误：

并且构建失败。如果管道有效，那就好。如果不是，则需要修复。但是没有人希望拥有不稳定的管道。
