IDEA plugin dev: tools.jar not found
Answered
Hi,
I create a plugin project for intellij using intellij. Then Run it,
I get an error in the console:
```
JDK Required: 'tools.jar' seems to be not in IDEA classpath.
Please ensure JAVA_HOME points to JDK rather than JRE.
```
and the same error as an ugly Java modal.
I use the `IntelliJ IDEA IU-171.4249.4` SDK that is created by intellij, I tried to add the tools.jar directly (last line in the last screenshot).
What is missing?
I'm on macos 10.12.4 (16E195)
IntelliJ IDEA 2017.1.2 EAP
Build #IU-171.4249.4, built on April 12, 2017
...
JRE: 1.8.0_112-release-736-b16 x86_64
JVM: OpenJDK 64-Bit Server VM by JetBrains s.r.o
Mac OS X 10.12.4
Bests,

tools.jar has to be added to the "IDE SDK" classpath in your case.
Try using a standalone JDK outside of IntelliJ IDEA installation directory.
I added tools.jar to the IDE SDK, no change.
If I use another SDK I get a "Run Configuration Error: Wrong SDK type for plugin 'my-plugin'".
Thanks for looking into this Serge.
Please show the classpath of the "IDE SDK" configuration.
No change with an external tools.jar either,
"JDK Required: 'tools.jar' seems to be not in IDEA classpath.
Please ensure JAVA_HOME points to JDK rather than JRE."
Use standalone JDK installation for IDE SDK (not inside IntelliJ IDEA directory).
You can get one from https://bintray.com/jetbrains/intellij-jdk/ or use the standard Oracle JDK.
Make sure it's JDK and not JRE.
In the plug-in run/debug configuration the same JDK has to be used.
Sample configuration:
As you can see, the standalone 1.8 JDK is used, not JDK from the IntelliJ IDEA installation like on your screenshots (IDE SDK).
Go it, it's working now, thanks Serge!
