Kotlin could not find the required JDK tools in the Java installation

Question

When running ./gradlew clean build I get following message:

> Task :compileKotlin FAILED

FAILURE: Build failed with an exception.

* What went wrong:
Execution failed for task ':compileKotlin'.
> Kotlin could not find the required JDK tools in the Java installation '/usr/lib/jvm/java-8-openjdk-amd64/jre' used by Gradle. Make sure Gradle is running on a JDK, not JRE.

I have JDK, JAVA_HOME is set properly, so is update-alternatives.

# java -version
openjdk version "1.8.0_191"
OpenJDK Runtime Environment (build 1.8.0_191-8u191-b12-2ubuntu0.16.04.1-b12)
OpenJDK 64-Bit Server VM (build 25.191-b12, mixed mode)

# update-alternatives --config java
There are 3 choices for the alternative java (providing /usr/bin/java).

Here's gradle build with stacktrace enabled:

So from what I can see, it's failing during search for tools.jar - which I have under /usr/lib/jvm/default-java/lib, since the configured path is to JDK.

My gradle.build - just in case:

plugins {
    id 'org.jetbrains.kotlin.jvm' version '1.3.11'
}

ext {
    ktorVersion = "1.1.2"
}

group 'com.example'
version '1.0-SNAPSHOT'

repositories {
    jcenter()
    mavenCentral()
}

dependencies {
    implementation "org.jetbrains.kotlin:kotlin-stdlib-jdk8"
    implementation "io.ktor:ktor-server-netty:$ktorVersion"
    implementation "io.ktor:ktor-jackson:$ktorVersion"
    implementation "io.ktor:ktor-freemarker:$ktorVersion"
    implementation "io.ktor:ktor-auth:$ktorVersion"
    implementation "ch.qos.logback:logback-classic:1.2.3"
    implementation 'io.github.microutils:kotlin-logging:1.6.22'
    implementation 'org.koin:koin-ktor:2.0.0-beta-3'
    implementation 'org.litote.kmongo:kmongo-coroutine:3.10.0'
}

compileKotlin {
    kotlinOptions.jvmTarget = "1.8"
}
compileTestKotlin {
    kotlinOptions.jvmTarget = "1.8"
}

I'm truly at a loss, would appreciate some help.

If any more information is needed let me know and I'll do my best to provide it.

Did you figure out how to fix it? Because I am fighting it for two days already and can't figure out what's the matter. — redCuckoo, Oct 18 '20 at 18:12
The solution is in the error message! "Make sure Gradle is running on a JDK, not JRE." JAVA_HOME must point to a JDK path and the message says yours is pointing to a JRE. See https://stackoverflow.com/a/63576967/12534 — Christian Davén, Dec 05 '22 at 14:47

I solved a similar problem in MacOS (Big Sur). In my case I was running a React Native project and got the following error when trying to build to Android:

* What went wrong:
Execution failed for task ':bugsnag_react-native:compileDebugKotlin'.
> Kotlin could not find the required JDK tools in the Java installation '/Library/Internet Plug-Ins/JavaAppletPlugin.plugin/Contents/Home' used by G
radle. Make sure Gradle is running on a JDK, not JRE.

I followed this article for uninstalling the JRE on MacOS. Slightly modified to make the process reversible, here are the steps:

cd /Library/Internet\ Plug-Ins/
mv JavaAppletPlugin.plugin DELETED-JavaAppletPlugin.plugin
cd /Library/PreferencePanes/
mv JavaControlPanel.prefPane DELETED-JavaControlPanel.prefPane

When you receive Permission denied use sudo before commands.

I then cleared my Gradle folder. I don't know if this is necessary, but it worked for me:

rm -rf ~/.gradle

Finally, I rebuilt my project (react-native run-android) and everything worked.

I'm not sure removing the JRE is the best solution since you may need the JRE for other things, but I have not noticed any ill effects. Also, it appears I already had a JDK installed which may not be true for all Mac users.

Since there are not any good answers on Stack Overflow that address this problem on MacOS, I figured I'd post my solution here.

This worked for me and as mentioned in MacOS Big Sur. I also omitted clearing the gradle folder. Thanks for this! – srinij Dec 09 '20 at 23:23
Thanks you saved me ... every time Apple does a major update some JDK/gradle/... stuff breaks – Drejc Dec 16 '20 at 10:10
With all these steps I also had to install latest jdk https://www.oracle.com/java/technologies/javase-jdk15-downloads.html and everything worked. – Mikhail Vasilev Jan 19 '21 at 10:09
"rm -rf ~/.gradle" was no necessary to do for me, I'm working on android studio and native code, I just upgraded to Big Sur and I faced this issue – dicarlomagnus Feb 04 '21 at 21:31
Thanks dude, you've saved a lot of time to me. I upgrade to Mac Os Big Sur and same problem. Your fix has worked for me – Josue Feb 11 '21 at 13:14
In my case in MacOS after update to BigSur I had to update my JAVA_HOME path in the command line `echo export "JAVA_HOME=\$(/usr/libexec/java_home)" >> ~/.bash_profile` – Roman Nazarevych Feb 16 '21 at 17:55
Just updated to BigSure, same issue in Android Studio. I've followed the suggestion and renamed the `JavaAppletPlugin` and the `JavaControlPanel`, also I've set the JAVA_HOME path as suggested in the previous comment. Everything went fine, didn't have to remove the `.gradle` folder, after checking that the compilation works again I removed completely the previous plugins. Thank you! – Paolo Moschini Mar 08 '21 at 09:36

android studio also offers jdk. If you specify that jdk as below, it will succeed

export PATH=$PATH:/Applications/"Android Studio.app"/Contents/jre/jdk/Contents/Home/bin
export JAVA_HOME=/Applications/"Android Studio.app"/Contents/jre/jdk/Contents/Home

This was working for me but now i get an error saying invalid path after an android studio update. I needed to change the second line to `export JAVA_HOME=/Applications/"Android Studio.app"/Contents/jre/Contents/Home` – James Aug 13 '21 at 18:53
this worked for me, if someone sure that he has java so that is the correct answer – Mohammad Rabiee Nasri Nov 17 '21 at 20:35
This is definitely the answer for Mac with @James update – maddesa Dec 24 '21 at 20:08

Following MacOS update to Big Sur, I was seeing the same problem as Tom Aranda above. Upon further investigation, I came across this SO post and this led me to this radar. I wasn't happy removing the JRE as per Tom's answer and so have worked around my own install with details from the other posts.....

My previous declaration of JAVA_HOME was in ~/.zshrc as

export JAVA_HOME=`/usr/libexec/java_home -v 1.8`

but Big Sur appears to have updated the default JRE version to 1.8 also. So my JAVA_HOME needs to be more precise with its filtering.

% /usr/libexec/java_home -V
Matching Java Virtual Machines (2):
    1.8.251.08 (x86_64) "Oracle Corporation" - "Java" /Library/Internet Plug-Ins/JavaAppletPlugin.plugin/Contents/Home
    1.8.0_241 (x86_64) "Oracle Corporation" - "Java SE 8" /Library/Java/JavaVirtualMachines/jdk1.8.0_241.jdk/Contents/Home
/Library/Internet Plug-Ins/JavaAppletPlugin.plugin/Contents/Home

And I now export as

export JAVA_HOME=`/usr/libexec/java_home -v 1.8.0_241`

Now this isn't ideal as it'll break the next time I update the JDK.

As per the details in the radar and the other SO post I also need to ensure that any existing exported JAVA_HOME is unset before exporting again, so my new entry in ~/.zshrchas now become

unset JAVA_HOME;export JAVA_HOME=`/usr/libexec/java_home -v 1.8.0_241`

Upon terminal relaunch, my previously failing gradlew commands now function as before.

To me this feels like a better solution as I've not removed any libs and I have only affected java home from my own terminal commands. It's a shame that I need to specify the precise version as this will break at some point in the future.

on BIG SUR people who get this error have probably got a custom java installation. Remove it with the following

sudo rm -fr /Library/Internet\ Plug-Ins/JavaAppletPlugin.plugin
sudo rm -fr /Library/PreferencesPanes/JavaControlPanel.prefPane
sudo rm -fr ~/Library/Application\ Support/Oracle/Java

after that unset any custom JAVA_HOME you have and remove it from your shell and it should start working again.

I got the exact same problem. I solved it by installing OpenJDK 8 JDK. My machine is running centos so here is my installing command

sudo yum install java-1.8.0-openjdk-devel.

I learned from this article that there are two different Java packages, Java Runtime Environment (JRE) and Java Development Kit (JDK). JRE is for running Java programs, and JDK is for developing Java applications. I only had had JRE installed, but not JDK. After installing JDK, my build ran successfully

@IgorGanapolsky, yum is the package manager for Cent OS. – Chris Jan 04 '21 at 11:09 — Chris, Jan 04 '21 at 11:09

> Kotlin could not find the required JDK tools in the Java installation '/usr/lib/jvm/java-8-openjdk-amd64/jre' used by Gradle. Make sure Gradle is running on a JDK, not JRE.

it's set to /usr/lib/jvm/java-8-openjdk-amd64/jre.

Should set the JAVA_HOME to /usr/lib/jvm/java-8-openjdk-amd64/

If your OS is Ubuntu, make suer to install openjdk jdk by sudo apt-get install openjdk-8-jdk

sudo apt install openjdk-8-jre-headless will install jre, not jdk

Also it might help to uninstall the jre version before install the jdk version, because they shared the same parent path, and I tried to install jdk without removing jre, which didn't solve the issue. – Katherine Chen May 19 '21 at 14:12

From the data provided, It is sure that java is in the environment path. But, It doesn't confirm that JAVA_HOME is set to a JDK directory. Are you sure JAVA_HOME is not set to /usr/lib/jvm/java-8-openjdk-amd64/jre instead of /usr/lib/jvm/java-8-openjdk-amd64or /usr/lib/jvm/default-java?

Because, If JAVA_HOME is set, then gradlew will ignore java binary in the PATH and execute $JAVA_HOME/bin/java which in turn will be available in System.getProperty("java.home") which is logged in this exception ( see jarSearchingUtil.Kt )

Otherwise, You can try declaring JAVA_HOME directly in the gradlew file

Things were all working fine before update to Mac Big Sur, I was using Jenkins on my local machine with Fastlane 'sh Fastlane beta' for firebase distribution. It was a flutter project.

I just added org.gradle.java.home=/Applications/Android Studio.app/Contents/jre/jdk/Contents/Home in gradle.properties. And this fixed my issue.

I solved the problem by deleting a kind of version of java.

I had 2 kinds of Java, as below picture.

But I got a failure when I was executing ./gradlew clean assembleRelease, it's remind me maybe the problem is about which JDK I used. failure

Then, I find the content of 2 kinds of java's home were different with each other. The left is which one I download from Oracle.

JAVA_HOME content diff

So, I tried to fix it by deleting the first java's home.(Compress the folder for copy at first).

It's work!

If you are using a Mac, the trick is to install the JDK from Oracle, they are now changing license policies so apparently it isn't totally free anymore for commercial use. That said, once you install, you find the JDK on the MAC at : "/Library/Java/JavaVirtualMachines/jdk-10.jdk/Contents/Home" if you go to gradle.properties, you can insert the line : "org.gradle.java.home=/Library/Java/JavaVirtualMachines/jdk1.8.0_301.jdk/Contents/Home" into the file. Restart Android studio, select the Android device, and it should work. Interestingly enough if you go to Finder, and navigate to the folder, then drag the folder into the gradle.properties file in textedit or vim, the path just shows up magically. I've been using Macs for over 10 years and only found that during this new endeavor into Android Studio. It did for me. Thanks to Stack Overflow community, it is a essential part of any application developer's toolkit.

I struggled alot with this. (MAC OS Monterey)

But what works for me now is

Installing the JDK 8 from Oracle's website. (Login was required)
Add org.gradle.java.home=/Library/Java/JavaVirtualMachines/jdk1.8.0_331.jdk/Contents/Home in the gradle.properties (jdk1.8.0_331.jdk was the name of my jdk folder, if you have another version you will have to use your own version / folder name there.)
I created a file called local.properties in the root of android folder in your project. There i added the line sdk.dir = /Users/USERNAME/Library/Android/sdk USERNAME should be your mac's username.

I tried declaring it as a home variable in the terminal but for some reason it wouldn't work. But telling the gradle.properties in step 2 worked it out :)

In my case, my lab has windows 7 and visual studio and android studio and flutter environment. When i Ran start debugging, same problem was happened.

To solve this problem,

First, Install Java Extension Pack by use extensions on visual studio.

Second, Follow Java Extension Pack, it required JDK 11 on config running screen.

Third, Download and install JDK(java develop kit) 11

Forth, When you install, you have to do check Path set on installation process. Maybe, it is not set Path automatically. you must check making path.

If you set and install correctly, It is appeared automatically at System environment variable as JAVA_HOME name. not user variable.

Run again main dart. you can see emulator correctly

In my case, using the system-wide installed tool gradle instead of the project tool ./gradlew works. That is, I run gradle ... instead of ./gradlew .... If gradle is installed on your machine, it should be configured correctly and know where Java is.

Note, I am on macOS, not sure about Linux and Windows, but I imagine should be the same.
