Changing Boot JDK

For earlier versions of JebBrain IDEs you can find the instructions in Selecting the JDK version the IDE will run under.

For later products, starting with build 141 (not sure about the exact build cutoff, could be earlier), you can add a boot jdk config file to the product's configuration directory with the full path of the location of the JDK you want the product to use:

Product	Boot JDK Config File
IntelliJ IDEA Ultimate & Community Edition	idea.jdk
PhpStorm	phpstorm.jdk
WebStorm	webstorm.jdk
PyCharm	pycharm.jdk
Other products probably follow a similar naming convention.	if you know another product's boot jdk config file then please add it to this list.

The list of directories used by the IDE is operating system dependent, see Directories used by the IDE to store settings, caches, plugins and logs – JetBrains Support
