SpringBoot打包时提示：Perhaps you are running on a JRE rather than a JDK?

场景

将SpringBoot打包时提示：

Perhaps you are running on a JRE rather than a JDK?

解决

Eclipse默认在jre上运行，maven install 编译需要jdk中的编译器，而jre中并没有

找到Windows-preferences-java-Installed JREs-Add-Standard VM--next

选择jdk的安装目录，点击Finish,此为默认安装目录。

添加完后，勾选为刚才添加的jdk

然后再选择Installed IREs下的Execution Environments,重新设置为jdk，然后关闭。
