A modern programming language that makes developers happier.

The packaging tasks should use the JRE pointed to by JAVA_HOME (when run from the command line).

You can use a normal JDK which contains all the tools for packaging and define the JRE you want to bundle with your app separately here:
```compose.desktop {
    application {
        mainClass = "MainKt"
        javaHome = JAVA_PACKAGE_HOME
        ...```
where JAVA_PACKAGE_HOME could be pointing to your JBR.

My app is packaging with JBR without setting `javaHome` in `application`. I just have this in IDEA:

But setting `javaHome` is probably the more robust way.

For me `~/Library/Java/JavaVirtualMachines/jbr-17.0.9-1/Contents/Home/bin` does have the `jpackage` and `jlink` binaries

The JBR that comes bundled with Android Studio could have those binaries stripped

Also in IDEA -&gt; File -&gt; Project Structure -&gt; SDKs -&gt; Plus button

What’s `JBR.isAvailable()`? It returning false seems to be a contradiction

print `System.getProperty("java.vendor")`

The JBRs from <https://github.com/JetBrains/JetBrainsRuntime/releases> do indeed not contain jpackage and jlink and thus cannot be used.

Yes, that once happened to me accidentally. Therefore I was surprised that the JBRs I examined either did not contain jpackage/jlink or, if the do contain it, it does not work. Does the <https://github.com/JetBrains/jewel/blob/main/decorated-window/src/main/kotlin/org/jetbrains/jewel/window/DecoratedWindow.kt|DecoratedWindow> in jewel now work with this?

By the way, the JBR in
```IntelliJ IDEA 2023.3 Beta (Community Edition)

does not seem to contain jpackage/jlink. Which version did you use?

I used the JBR installed by navigating to `File -&gt; Project Structure -&gt; SDKs -&gt; Plus button` from Intellij IDEA

IDEA version

installed JBR version
`17.0.9 (JetBrains s.r.o. 17.0.9+7-b1087.7)`

Ahhh, that worked. The packaged application reports:
```java.vm.name: OpenJDK 64-Bit Server VM

Is this runtime now also compatible with Jewel? I haven’t had the time to try that yet.
