今天在网上浏览网页,发现一片文章,介绍如何使用idea的 java 64位运行idea,用32位java运行程序。
设置环境变量,IDE_JDK_64,选择64位的jdk。在idea下有一个idea.bat文件,里面内容如下:
@ECHO OFF

:error
ECHO ERROR: cannot start IntelliJ IDEA.
ECHO No JDK found. Please validate either IDEA_JDK, JDK_HOME or JAVA_HOME points to valid JDK installation.

保存后,可以点击idea64位,进行运行,或者点解,idea.bat
