android - 项目未建由于

Question

我正在使用适用于 Eclipse 的 Android SDK 以及适用于 github 的 Egit 插件开发 Android 应用程序。
最近我在尝试与(远程)master 合并后尝试构建项目时遇到错误。我在问题窗口中列出了这个错误:

The project was not built due to "Error updating cache during move/delete.
The resource cannot be moved, renamed or deleted due to an internal error."

在我的错误日志中，我还有之前的Project > Clean:

我已经尝试寻找一些可能的解决方案，但未能找到任何有用的东西。
在我的项目名称旁边看到一个错误标记但我的任何类都没有标记后，我遇到了这个问题。
我首先搜索了该问题的可能解决方案，其中大多数解释为执行 Project > Clean，这就是我的构建错误出现在日志中的时候。
谢谢。

Answer 1

The resource cannot be moved, renamed or deleted due to an internal error. java.io.IOException: Cannot lock C:\Users\Jessbro\Project\.git\index

这将是由于存在一个文件: ...\.git\index-lock - 它的文件大小应该为 0

EGit 认为另一个 git 客户端正在执行独占操作。但是，我发现当 EGit 抛出异常(来自之前的操作)时，它无法清理自己的锁定文件!

要解决这个问题，请检查没有 git 客户端正在访问您的本地 git 存储库(也可以关闭 Eclipse)并简单地删除它。

其他想法:

• 升级 EGit!后来的版本比 9 个月前问题发布时要好。 (我在 git 工作目录中遇到了“Eclipse 链接文件夹”的问题。EGit 仍然可能因此而崩溃 - 但现在只是针对特定的 git 操作，而不是几乎每个 Java 重构操作!)

• 在 Windows 上，多个 git 客户端可以以令人讨厌的方式互相破坏，因为 Windows 文件锁定比在 Linux 上更“排他”(默认情况下 - 在调用“常规”C/Java 函数时)

旁白:实际上后来的问题非常严重，我几乎完全切换到命令行，只是暂时“附加”EGit(团队 -> 共享项目)只是为了 git annotate!这也节省了大量的内存。很遗憾，因为 EGit 似乎集成得很好。至少安装/拆卸非常快。
