推荐答案

Goto Windows -> Preferences

Java -> 已安装的 JRE -> 执行环境

JavaSE1.x -> JDE 1.x

如果你在Installed JRE中没有JDK，那么

If you don’t have the JDK in the Installed JRE, then

选择Installed JRE并添加JDK安装路径

Select the Installed JRE and Add the JDK installed path

让我们尝试将您的运行配置配置为全新安装

Let's try to configure your run configurations to clean install

点击黑色小箭头，然后点击运行配置

Click on the small black arrow and then Run Configurations

之后，您只需在 Maven 目标中进行全新安装，如下所示:

After, you just put clean install in your Maven goal, like this :

然后，尝试运行您的编译，我们将看到会发生什么... :)

And then, try to run your compilation, and we will see what happens... :)
