给IDEA设置单独的JDK

二、参考说明

https://intellij-support.jetbrains.com/hc/en-us/articles/206544879-Selecting-the-JDK-version-the-IDE-will-run-under

详情如下:

<product>.exe uses this JDK search sequence:

  1. IDEA_JDK / PHPSTORM_JDK / WEBIDE_JDK / PYCHARM_JDK / RUBYMINE_JDK /CLION_JDK / DATAGRIP_JDK environment variable (depends on the product,WEBIDE_JDK applies to both WebStorm and PhpStorm before version 2016.1)

  2. ..\jre directory
  3. system Registry
  4. JDK_HOME environment variable
  5. JAVA_HOME environment variable

idea64.exe uses this JDK search sequence:

  1. IDEA_JDK_64 environment variable
  2. ..\jre64 directory
  3. system Registry
  4. JDK_HOME environment variable
  5. JAVA_HOME environment variable

It’s also possible to start the IDE with <product>.bat file located in the bin directory, it uses the following JDK search sequence:

  1. IDEA_JDK / PHPSTORM_JDK / WEBIDE_JDK / PYCHARM_JDK / RUBYMINE_JDK/ CLION_JDK / DATAGRIP_JDK environment variable (depends on the product)
  2. ..\jre directory
  3. JDK_HOME environment variable
  4. JAVA_HOME environment variable

Environment variable must point to the JDK installation home directory, for example:

c:\Program Files (x86)\Java\jdk1.8.0_66
  • The actual JDK version used by the IDE can be verified in Help | About dialog (open any project to access the menu).
  • Define IDEA_JDK / PHPSTORM_JDK / WEBIDE_JDK / PYCHARM_JDK / RUBYMINE_JDK / CLION_JDK / DATAGRIP_JDK variable depending on the product to override the default version from IDE_HOME\jre.
  • Use Rapid Environment Editor to add/edit the variables, it will detect incorrect paths.
