本文解决IDEA在更换JDK版本后仍使用旧版本的问题，通过修改项目结构和关闭自动使用模块JDK设置，确保IDEA使用正确版本。

换过java jdk 版本之后，idea 运行发现这个问题，一开始认为是 没有设置 JAVA_HOME 后来设置注销重新打开 电脑也是没有用，

网上一片的说   改  Settings > java compiler  > javac 改成  eclipse 要是这样有用的话，我就不写这篇博客了，我发想改 eclipsek可以用，但是好像只针对 java8 的 ，我这里还有一种选项可以供你们选择

另一种姿势：

step 1: 选好你要用的 jdk版本   files  -- project structure 

 这里我选jdk10 

step2   取消 Use compiler from module target JDK when possible 选项

 点击ok 就好了

原因： IDEA  会记住之前用的jdk 目录，当你使用的上一个版本的jdk 卸载删除之后，idea还是 有记录存在，会去找上个版本的javac 地址，这样就不好了呀，我们就不让他自己找，我指定你用啥，你就用啥，真 好，舒服了。。

Settings > java compiler > 将javac 改成 eclipse；以上操作完毕后发现都不行。最后重新修改了jdk的位置才可以。

今天把项目的jdk版本从1.8换成1.7，在build项目时出现一下错误： Error:java: System Java Compiler was not found in classpath: java.lang.ClassNotFoundException: com.sun.tools.javac.api.JavacTool at java.net.URLClassLoader$1.run...

使用的idea plugins 中的scala插件版本有bug，请升级 1.我使用的idea为版本为2017.3.5，下载的scala插件版本也为2017.3.5这个版本有bug 2.这个bug直到2017.11.28才被修复，对应的是插件第九个版本2017.3.9，此时就被修复了 3我下载了2017.3.15这一版本，重新在idea安装了scala插件，重启解决问题

System Java Compiler was not found in classpath
慕孑晨的博客

原因：： IDEA 会记住之前用的jdk 目录，当你使用的上一个版本的jdk 卸载删除之后，idea还是 有记录存在，会去找上个版本的javac 地址，这样就不好了呀，我们就不让他自己找，我指定你用啥，你就用啥。二、jdk的版本不对应，也就是我们用idea在Project Structure里面设置的sdk不对。一、jdk没有安装好，cmd运行 java -version看一下。每天一个小问题，天天在成长，程序员的秃头之路！代码其实很简单就是一个main方法。为什么会出现这个问题呢？
