无法在 jenkins 中运行 Android 模拟器进行连接测试

Question

我正在尝试从 Jenkins 运行连接测试，并且无法从 Jenkins 服务器（ubuntu 18 VM）加载模拟器，但使用 -nowindow 标签我可以加载模拟器。

出现以下错误：

Fatal: This application failed to start because no Qt platform plugin could be initialized. Reinstalling the application may fix this problem.

为 qt 插件启用调试后，我能够看到详细的错误：

注意：我还为 QT 添加了环境变量，但没有任何效果。
