Multiple versions of IntelliJ possible? Follow

Hello pseudonym_ima,

I'm currently running IntelliJ 5.1. I'd like to install and trial
version 8 beta. Will doing so affect my version 5.1? I still need
version 5.1 to run and don't want to jeopardize it's functionality.

No, it wil not affect your version 5.1. Different versions of IntelliJ IDEA
use different configuration directories and don't affect each other.

Excellent! Thanks for the answer

Just want to verify.

I have IntelliJ versions 2018.3 and 2019.1 installed, and have implemented a plugin.

I run/debug my plugin (which generates an IntelliJ-IDE for a language I am working on) on the 2018.3 (Help shows 2018.3). However the debugged plugin's Help shows 2019.1 version.

Checking the Windows command set path, I can see the following 2 items:

1. IntelliJ IDEA Community Edition=C:\Program Files\JetBrains\IntelliJ IDEA Community Edition 2019.1\bin;

2. Path= ..... ;C:\Program Files\JetBrains\IntelliJ IDEA Community Edition 2019.1\bin;

There is no path reference to the 2018.3, therefore I assume when I run/debug my plugin on the 2018.3, it is building using 2019.1 libraries.

Is this expected?

How can I build/run/debug using its own version, which I started the project from?

You need to set a platform SDK as described here: https://www.jetbrains.org/intellij/sdk/docs/basics/getting_started/setting_up_environment.html

Hello Petr,

Based on the url, I set up a new SDK: IntelliJ Platform Plugin SDK, which points to "C:\Program Files\JetBrains\IntelliJ IDEA Community Edition 2018.3"

Now, when I try to run or debug the plugin, I get the error:

The supplied javaHome seems to be invalid. I cannot find the java executable. Tried location: C:\Program Files\JetBrains\IntelliJ IDEA Community Edition 2018.3\bin\java.exe

I have not found a way to overcome this JAVA_HOME issue. Tried the Switch Boot JDK as well. Tried setting my Windows environment with JAVA_HOME = C:\Program Files\Java\jdk1.8.0_191

The only way was still to use the original SDK: 1.8, which points to "C:\Program Files\Java\jdk1.8.0_191".

(Note about user: I am new to using IntelliJ, about 6 months. Thanks for any continued advice.)

Could you please share idea.log ("Help | Show log ") using any file sharing service?
