Boot JDK for running Idea Plugin target

Are you using "Plugin" run configuration from DevKit? What version of IntelliJ IDEA are you using? Switching JRE does work for me here.

Hi Yann, 

I use 2018.3 Community and "Plugin" run configuration. In it I set JRE to /Applications/IntelliJ IDEA CE.app/Contents, but when running plugin under debug it ends with running idea under system JDK like this:
/Library/Java/JavaVirtualMachines/jdk1.8.0_151.jdk/Contents/Home/bin/java -agentlib:jdwp=transport=dt_socket,address=127.0.0.1:64628.........

Your IntelliJ Platform SDK "internal Java Platform" should point to the bundled JetBrains JDK instead (point to /Applications/IntelliJ.app/Contents/jdk/Contents/Home)

Hi Yann, 

Are you referring Platform Settings->SDKs, my `Intellij Platform Pluggin Sdk` ? 
its set to /Applications/IntelliJ IDEA CE.app/Contents

When I try changing it to /Applications/IntelliJ.app/Contents/jdk/Contents/Home I receive "The selected directory is not valid home for Intellij Platform Plugin SDK"

same error if I try to create JDK for this location (/Applications/IntelliJ.app/Contents/jdk/Contents/Home )

The IDE stopped recognizing the bundled JDK as a valid JDK a while back. I never investigated what files are missing from the bundled JDK that cause this but create a hybrid JDK consisting of bundled JDK and files from Oracle JDK (1.8u152 or close to the version of the OpenJDK) to fill in the missing files.

I have an old blog post on this so the versions and paths need to be adjusted for current release but it should still apply. https://vladsch.com/blog/12 

The result is a bundled JDK which the IDE recognizes as valid and has the benefit of better font rendering and bug fixes of the bundled JDK.

Please try again, "Internal Java Platform" can be set to bundled JDK for me.

Hi Yann, 

I can see there only JDKs I configured. Same time as mentioned above I can't create JDK configuration with bundled JDK path. 

How "JB JDK" is  defined ? What is its JDK home path ? 
Also you use Idea 2019.1 while I use 2018.3 CE

Reagards,

Demyan

"JB JDK" is plain JDK with path /Applications/IJ.app/Contents/jdk/Contents/Home

Yann as mentioned above it doesn't work, check comments above, also one from Vladimir. 

Sorry, indeed reproduced with default installation of IJ. It worked with my local dev-installation, though. Will investigate further.

@Yann, any progress on investigation? I am running into the same problem - my local Sandbox AppCode IDE does not run under JB SDK environment. I have a Gradle Project.

The following suggestion did not work for me because I have a Gradle Project:
https://stackoverflow.com/questions/55783215/intellij-plugin-development-freezes-target-intellij-instance/55783247

And I don't see JB JDK as an option under "Internal Java Platform". There's only one option - 1.8.

Also tried putting `appcode.jdk` file with correct JB JDK path to build/sandbox config folder as well cache/sandbox.

Nothing works. Sandbox IDE keeps looking into the default JRE and keeps freezing in a minute after its launch. Exactly the behavior described at the stackoverflow link posted above.

Dmitry Goliy, " I have a Gradle Project." using "runIde" has these options https://github.com/JetBrains/gradle-intellij-plugin/#running-dsl

Thank you @Yann! Missed that part of the documentation.

runIde {
    jbrVersion = 'jbrex8u152b1402.1'
}

Worked like a charm!
