还有另一个“由于构建路径不完整，所以未构建该项目” [英] Yet Another 'The project was not built since its build path is incomplete'
问题描述
我有一个Android项目，已经在Eclipse Indigo中愉快地构建了数周。 我没有更改任何设置，库或工作区组件，也没有添加或删除任何文件。几个小时前，我正在做一个运行方式来在电话上运行我的应用程序，而Eclipse却很难解决。我什至无法在任务管理器中将其杀死，所以我重新启动了PC。
现在，当我尝试构建应用程序时，我会得到
未构建项目，因为其构建路径不完整。找不到java.lang.Object的类文件。修复构建路径，然后尝试构建该项目。
我删除了gen并进行了清理并以相同的结果进行构建。在构建路径的项目属性的库选项卡中，它显示
- Android Dependencies
- Android私有库
- 无法获取该项目的系统库。
任何想法上？这种Eclipse构建路径不完整错误非常普遍，但是当我搜索Stack Overflow和Google时，大多数情况似乎与导入新项目，移动工作空间，更改库或其他我没有做的事情有关。 p>
预先感谢！
我已解决问题。
我做了一个 File> Switch Workspace ，然后切换到另一个有不同项目的工作区。然后，我又回到原来的工作区，一切都很好。
因此，我们可以将其添加到非常一长串的民间疗法中， Nostrum，旧妇的故事，迷信和其他一些软件知识，伴随着困扰Eclipse的各种怪异错误。我肯定希望Android Studio会比这更好！
I have an Android project that I've been happily building for weeks in Eclipse Indigo. I have not changed any settings, libraries, or workspace components, or added or removed any files. A few hours ago I was doing a "Run as" to run my app on a phone and Eclipse did a hard hang. I couldn't even kill it in Task Manager so I rebooted my PC.
Now when I try to build my app I get "The project was not built since its build path is incomplete. Cannot find the class file for java.lang.Object. Fix the build path then try building this project"
I deleted gen and did a clean and build with the same result. In the project Properties for the build path, in the Libraries tab it shows
- Android Dependencies
- Android Private Libraries
- Unable to get system library for the project.
Any idea what's going on? This Eclipse "build path is incomplete" error is very common but when I search Stack Overflow and Google, most of the cases seem to be related to importing new projects, moving workspaces, changing libraries or other things I didn't do.
Thanks in advance!
I fixed my problem.
I did a File>Switch Workspace and switched to another workspace that had a different project in it. Then I switched back to my original workspace and everything was fine.
So we can add this to the very long list of folk-remedies, nostrums, old-wives-tales, superstitions and other bits of software lore that accompany the various weird bugs that afflict Eclipse. I sure hope Android Studio turns out to be better than this!
