C++ Eclipse Luna CDT - java.lang.NullPointerException
C++ Eclipse Luna CDT - java.lang.NullPointerException
更新：
好像只有我的Event_Creator项目有这个问题。我的所有其他项目都可以编译并 运行 成功。
更新 2：
当我要构建我的项目时，我只能选择"default"构建，通常我应该看到调试和发布。所以我猜我的项目构建设置有问题？
我在使用 eclipse luna 时遇到问题，每当我尝试构建我的项目时，我都会收到此错误：
Errors occurred during the build.
Errors running builder 'CDT Builder' on project 'Event_Creator'.
Internal error building project Event_Creator configuration Default
java.lang.NullPointerException
Internal error building project Event_Creator configuration Default
java.lang.NullPointerException
Event_Creator那就是我的节目了。
我真的不知道是什么原因造成的，我已经在这个程序上编程了大约 2 周并且我已经能够很好地编译它，但是今天这只是发生了。
我尝试了很多东西，甚至删除了 eclipse 然后重新下载。我也尝试创建新的工作区，看看我当前的工作区是否有问题，但我仍然遇到同样的问题。
我也在使用 C/C++ 工作区，所以我确信我没有使用一些奇怪的 java 工作区，这些工作区可能会弄乱我。
我正在使用 minGw 编译器和这个 CDT 存储库：
http://download.eclipse.org/tools/cdt/releases/8.6/
提醒一下，我已经编译了两个星期了，这只是今天当我启动计算机并打开 eclipse 时发生的。
在 \Eclipse\Workspaces.metadata 的 .log 文件中，我发现了这些与空指针错误相关的条目，尽管我不知道它们的真正含义。

好的，因为我注意到 Event_Creator 项目只有 "default" 构建选项，而我的其他项目（我可以构建）有 "debug" 和 "release" 选项，我刚刚创建了一个新的空项目并手动将我的文件移动到该项目中，然后我打开了 eclipse，刷新了我的新项目，瞧瞧，我可以构建它了。
我假设旧目录中的项目文件发生了问题，导致我的构建被破坏。
