所有文件夹上的红色X [英] Red X on all folders

问题描述

因此，我已经使用Eclipse两年了，最近又切换到了Netbeans.我切换回Eclipse，以便可以处理一些SQL项目，但是当我打开Eclipse时，出现了很多红色x.我以前从未遇到过，也不知道如何摆脱它.

So I have used Eclipse for a couple years now, and recently switched to Netbeans. I switched back to Eclipse, so I can work on some SQL projects, but when I opened Eclipse, a whole bunch of red x's appeared. I have never come across this before and don't know how to get rid of it.

推荐答案

清理项目，然后检查JVM设置.

打开项目"菜单，然后选择清理..."，然后选择清理所有项目"，然后单击确定".

Open the "Project" menu and choose "Clean..." and then select "Clean all projects" and click "OK".

如果这不起作用，请检查项目设置.确保将其配置为使用系统上实际安装的JVM.我的猜测是，因为我可以看到突出显示了标准JVM类，所以您是选择全局使用不再安装在系统上的特定JVM.

If this doesn't work, then check the project settings. Make sure it is configured to use a JVM which is actually installed on your system. My guess, since I can see standard JVM classes highlighted, is that you had chosen to globally use a specific JVM which is no longer installed on your system.
