trying to solve an <https://gradle-community.slack.com/archives/CAHSN3LDN/p1711642049745839|issue I have>, I'm launching Gradle from the console `./gradlew LineDemo --info`
I specifically selected the jvm 21 to run with, in my `build.gradle.kts` with
```kotlin {
    jvmToolchain(21)```
 but for some reasons Gradle keeps selecting jdk11, which is also in my `JAVA_HOME`
reading the docs <https://docs.gradle.org/current/userguide/toolchains.html#sec:precedence|Toolchain installations precedence>, they state
> 1. the installation currently running Gradle is preferred over any other
What's that?
And why isn't 21 getting chosen?

<https://gist.github.com/elect86/bc701557170b19c99ba679e978521b4c|here> some log/info on the jdk selection

&gt; Java home is different.
Does `JAVA_HOME` matter in this? I cannot believe I shall change it to match the jdk I actually want

setting `JAVA_HOME` to 21 does work indeed

The snippet you shared is about the Java that is used to run the Gradle daemon.
The Java version you use to run Gradle has nothing to do with the JVM Toolchain you set.
That's the point.
Using JVM Toolchain you decouple the Java version you use to run Gradle from the Java version used to compile / run / ... your project's code.

This way you can for example run Gradle using Java 8 while still building Java 21 code.

The "the installation currently running Gradle is preferred over any other" means, that if there are multiple Toolchains that match the requested toolchain and one of them is the Toolchain that is used to run Gradle, then that toolchain will be taken.
