This is a preferred way tell projects which JDK container to use, especially true if two or more devs are using the same version controlled eclipse project folder.

这是告诉项目使用哪个 JDK 容器的首选方式，尤其是如果两个或多个开发人员使用相同的版本控制的 eclipse 项目文件夹。

列出您计算机上安装的一个或多个 JDK。Eclipse 默认名称为 jdk1.X.X_XX，您应该保持原样。切勿直接链接项目构建设置以使用这些名称。

Window/Preferences/Java/Installed JREs/Execution Environments

刚刚遇到这个问题，上面的解决方案不起作用，至少对我来说不是。

Instead I went the solution provided here:http://www.javaworkspace.com/VMNotFound.do

Essentially you go to the directory C:\projects\WORKSPACE.metadata.plugins\org.eclipse.debug.core.launches

基本上你去目录 C:\projects\WORKSPACE.metadata.plugins\org.eclipse.debug.core.launches

In there search for the string of the JDK that that eclipse is moaining about & change it to the name of your installed JDK that you want to use that eclipse knows about.

在那里搜索 Eclipse 正在抱怨的 JDK 字符串并将其更改为您要使用的 Eclipse 知道的已安装 JDK 的名称。

You can change what JRE the ant bulid file is launched with inside eclipse.

您可以更改在 eclipse 中启动 ant bulid 文件的 JRE。

Right click on the ant file in the ant view and select "Run As"->"Ant..." from the context menu.

在 ant 视图中右键单击 ant 文件，然后从上下文菜单中选择“Run As”->“Ant...”。

Then in the launch dialog select the JRE tab. Note the error message at the top if it can't find the JRE that it expects.

然后在启动对话框中选择 JRE 选项卡。如果找不到预期的 JRE，请注意顶部的错误消息。

Select a JRE that you have installed or manage install a new one. You can also add vm arguments (enable logging or change memory alocation) if you need to in this dialog.

选择您已安装的 JRE 或管理安装一个新的 JRE。如果需要，您还可以在此对话框中添加 vm 参数（启用日志记录或更改内存分配）。

The last answer is absolutely correct, however a fast track way is to delete the project reference from eclipse (make sure to keep unchecked delete source) and import your project folder again. This way the project configurations are reset by eclipse using the new jdk. But a wonderful post it did help me.

最后一个答案是绝对正确的，但是快速的方法是从 eclipse 中删除项目引用（确保保持未选中的删除源）并再次导入您的项目文件夹。通过这种方式，eclipse 使用新的 jdk 重置项目配置。但是一个很棒的帖子确实帮助了我。
