< kbd> Java - > 已安装的JRE - > 执行环境

Java -> Installed JREs –> Execution Environment

选择安装 JRE 并添加 JDK 安装路径

Select the Installed JRE and Add the JDK installed path

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

点击小黑色箭头，然后运行配置

Click on the small black arrow and then Run Configurations

之后，您只需将干净安装在您的Maven目标中，如下所示：

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