Answer 1

Be sure to check and correct JDK version in these 3 places:

1. Check Preferences -> Build,... -> Build Tools -> Gradle -> Gradle JVM:
2. Check Project Structure -> Project Settings -> Project -> Project SDK:
   
3. Check Project Structure -> Platform Settings -> SDKs:

Fixing gradle.properties is a dirty workaround. Better fix this at the IDE level.

Answer 2

Though I did not find the root cause where the different javaHomes have been taken from, at least I found a workaround that worked for me:

Try setting the following in your gradle.properties (either in $HOME/.gradle/ or in your project build dir):

org.gradle.java.home=/usr/lib/jvm/java-8-openjdk-amd64

Answer 3

IntelliJ broke when I copied tools.jar to a jre/lib, attempting to make hot attach work.

Answer 4

Worked like magic.. have been struggling for 2 days now, just add:

org.gradle.java.home=/Library/Java/JavaVirtualMachines/jdk1.8.0_162.jdk/Contents/Home

in ~/.gradle/gradle.properties file.

Answer 5

I ran into the same problem. This answer helped me.

Solution: In the bin folder of IntelliJ where you have it installed, run idea64.exe not idea.exe.

Answer 6

Fwiw - Had a similar thing after, and just reopening the project by picking the build.gradle file fixed it. (Also, done brew cask install java which placed jdk 10 in the default path)

Answer 7

For me this is solved when I selected the Project SDK option in gradle JVM. Even it was same when selected manually.

the preference window in intellij

Answer 8

The mentioned methods did not work for me. I am using Big Sur 11.4, M1 mac.

Remove Java like in the link below and reinstall it: https://actonnotes.wordpress.com/2020/11/22/how-to-remove-openjdk-version-15-on-apple-macos/

Answer 9

I struggled it whole day. For my case, it's not related to intellij. But as the repo uses an very outdated version of gradlew of 4.9. And it always complain a about a particular pid in the same error message. Which when I using jps or ps, it wasn't there. That drives me crazy. I reboot my machine many times, it still complains about the same pid. Later I found it cached the pid in the folder of: ~/.gradle/daemon/.... Such a dumb error message and logic. The finally I solved this problem but cleanup the whole ~/.gradle folder.

Answer 10

Java home is different.
Expecting: '/Users/******/.sdkman/candidates/java/current' but was: '/Users/*****/.sdkman/candidates/java/11.0.16.1-zulu/zulu-11.jdk/Contents/Home'.


Please configure the JDK to match the expected one.

for me me none of any of those suggestion worked. I am using mac with sdk man to manage the jdks. I checked gradle wrapper version in gradle/wrapper/gradle-wrapper.properties and updated from 6.8.2 to 6.9.3 and it worked.
