【问题描述】：

在我的机器上本地成功构建了我的应用程序，并且在单击以打开 Kotlin Activity 时运行良好，例如：

galleryLayout.setOnClickListener(view -> startActivity(new Intent(PreferencesActivity.this, GalleryActivity.class)));

但是在 Jenkins CI 上成功构建后，点击操作会导致应用崩溃：

这是我的build.gradle，如果您有任何想法，请提供帮助。谢谢！

【解决方案1】：

运行 gradle clean 并重试构建。不确定您的 Jenkins 脚本以及 CI 工作流程的运行方式，但始终建议在构建之前进行清理。

为什么不在此处发布您的 Jenkinsfile / Jenkins CI 脚本 =)
