Gradle is using uninstalled version of Java. How do i reconfigure it?
I created a Kotlin project and whenever I try to get the source sets from it using the command `gradlew sourcesets`I the following error:
Copy code
D:\Development\Intellij\KotlinTest>gradlew sourcesets
Starting a Gradle Daemon, 1 busy and 4 stopped Daemons could not be reused, use --status for details

> Configure project :
Directory 'C:\Program Files\Eclipse Adoptium\jdk-17.0.6.10-hotspot' (Windows Registry) used for java installations does not exist

FAILURE: Build failed with an exception.

* What went wrong:
Task 'sourcesets' not found in root project 'KotlinTest'.

* Try:
> Run gradlew tasks to get a list of available tasks.
> For more on name expansion, please refer to <https://docs.gradle.org/8.7/userguide/command_line_interface.html#sec:name_abbreviation> in the Gradle documentation.
> Run with --stacktrace option to get the stack trace.
> Run with --info or --debug option to get more log output.
> Run with --scan to get full insights.

I looked into this article: https://discuss.gradle.org/t/gradle-is-trying-to-use-a-jdk-that-has-been-uninstalled-from-my-system/43202 But deleting the available daemons didn't help. Btw, I am executing the command from the CLI and there is no IDE involved in the process.
I have 2 versions of java installed - 19.0.2 and 22.0.3. I previously had 17.0.6 but I uninstalled it long ago.

Not super familiar with Windows CLI but Gradle is probably going to use what’ in your 
PATH
or 
JAVA_HOME
, double check those environment variables
t
But gradle has a priority order to query for the Java Home correct? And if so, why does this command not work? Nor does setting the gradle.properties to use the specified java home works.
Copy code
D:\Development\Intellij\KotlinTest>gradlew sourcesets -Dorg.gradle.java.home="C:\Users\ranja\.jdks\openjdk-19.0.1"

That’s unexpected... Maybe the java mentioned in the error is the java used by a misconfigured toolchain and not the java used to run Gradle? Double check the version of Java used in a build script by dumping `System.getProperty("java.version")`to a build.gradle file?
t
That "(Windows Registry)" in the error message likely means the 17 version wasn't uninstalled properly and left some entries in the registry.
Anyway, that doesn't appear to be the source of the build failure, it looks like an info/warning message (probably when Gradle discovers available toolchains; but doesn't necessarily mean that it tries to use it). The true failure is "Task sourcesets not found"
☝️ 2
➕ 1
t
But in a standard java/kotlin project we have default source sets - 
main
and 
test
. Then why do we don't have the task 
sourcesets
available?
and for the toolchains it is configured to use jdk 19:
Copy code
kotlin {
    jvmToolchain(19)
}
t
Gradle itself does not define a 
sourcesets
task, nor any of the built-in plugins. Use 
./gradlew tasks
or 
./gradlew tasks --all
to list the available tasks (for the root project)
v
Just a wild guess, but it is probably 
sourceSets
, not 
sourcesets
t
> Just a wild guess, but it is probably 
sourceSets
, not 
sourcesets
But i retrieved the source sets of other projects using the command 
gradlew sourcesets
v
Ok, as I said, was just a wild guess
Can you show a build 
--scan
URL?
t
Okay, wait.
v
And maybe also one for running in a project where it works if possible, if not even more important
t
The standard kotlin project I have: https://scans.gradle.com/s/45iumxl2qcjjy (which fails)
This is the android java project I retrieved the source sets for: https://scans.gradle.com/s/f3ap5bczwchl2
v
Yes, I was right, the successful is the important one
It is indeed 
sourceSets
, not 
sourcesets
even if it works. But the important part is, that this task is coming from the Android Gradle Plugin, not the Kotlin Gradle Plugin, so you can only use it in an Android build unless you create such a task manually or find another plugin that adds such a task for non-Android projects: https://scans.gradle.com/s/f3ap5bczwchl2/timeline
t
Okay. I will have to look into the plugins then. Thanks for the help!

The project contains a 
sourceSet
property of type 
SourceSet container
. Isn't that what a sourceSet task would return?

Also how could I get rid of the remaining registry files for the uninstalled version of java? It is really annoying for this message to pop up again and again:

I don't know "what a sourceSet task would return". The task can do whatever you want. And I have no idea what the Android Gradle Plugin task of that name does, as I'm not into Android development.
Also how could I get rid of the remaining registry files for the uninstalled version of java? It is really annoying for this message to pop up again and again:
Clean your Windows registry. But be super carefull, if you do the wrong thing, you can harm your whole Windows installation. Here you find the Registry places Gradle checks: https://github.com/gradle/gradle/blob/master/platforms/jvm/jvm-services/src/main/j[…]/gradle/jvm/toolchain/internal/WindowsInstallationSupplier.java Alternatively install that JDK again and then properly uninstall it which should usually also clean that entry from the registry.
