Boot JDK for running Idea Plugin target

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

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.

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.

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

runIde {
    jbrVersion = 'jbrex8u152b1402.1'
}

Worked like a charm!

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