我的项目是在3周前成功编译的。我避免更新AppCelerator组件，因为我项目的某些模块需要该特定版本。
我没有自3周前更新Java(1.8 131(Appcelerator CLI或SDK。我使用的SDK版本是6.0.2。
我无法解开为什么钛为什么现在在"构建Java源文件"阶段显示此错误：

事先感谢您的帮助，对我的英语不好。
更新(2017-07-05(：
我发现了这个appcelerator jira，也有同样的问题：https://jira.appcelerator.org/browse/timob-24895
我正在等待官方的工具。
您是否尝试过在编译之前清洁项目目录？如果您正在使用Studio，只需转到菜单中的Project/Clean，然后选择您的项目，或者您可以使用命令行工具(http://docs.appcelerator.com/platform/latest/platest/#！/guide/titanium_cli_tasks-section-src-38931164_titaniumclitasks-cleanyourbuildfolder(
显然是我的Linux内核(Ubuntu 16.04(的4.4.0-81版。目前，我的解决方案已经开始使用4.4.0-79版本启动，以便通常进行编译。
