【问题描述】：
在 Windows 7 64 位上的 Eclipse Neon.1 中，每次运行 bat 文件时都会出现错误。出现一个弹出框。我已经删除了 Eclipse Neon.1 并使用全新的工作区安装了两个 Neon.1。
我相信我在计算机的某个地方丢失了某种文件。但我不知道文件在哪里，是什么。
弹出框标签：
Multiple problems have occurred.
框内留言：
An error has occurred. See error log for more details.
错误日志 - 事件详情 留言：
Problems occurred when invoking code from plug-in: "org.eclipse.jface".

我遇到了同样的问题，因为我尝试打开 *.bat 文件并选中“使用默认系统编辑器”。摆脱文件关联后，它几乎可以像以前一样工作。
