我只是无法弄清楚这一点，并且不确定在哪里查看或如何读取日志文件。有人可以帮忙吗？这是因为 Kotlin 吗？
这是错误消息： Gradle sync failed: Cause: org.gradle.api.internal.file.DefaultSourceDirectorySet.(Ljava/lang/String;Lorg/gradle/api/internal/file/FileResolver;)V 查看 IDE 日志了解更多信息详细信息（帮助 | 显示日志）（3 秒 374 毫秒）
该项目是来自 Github 的 DroidPlanner/Tower。https://github.com/DroidPlanner/Tower。我无法使其同步...任何帮助将不胜感激！
