在Windows 7 64位的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。我删除了Eclipse Neon.1并安装了Neon.1和一个新的工作区。
我相信我错过了计算机上的某种文件。但我不知道文件的位置和内容。
弹出框标签：
Multiple problems have occurred.
框中的消息：
An error has occurred. See error log for more details.
错误日志 - 事件详细信息 消息：
Problems occurred when invoking code from plug-in: "org.eclipse.jface".
异常堆栈跟踪：
