Hello everyone I am trying to create and run a react native app. I run npx react-native init rn4 but when I run npm run android I have this error:

> Task :react-native-gradle-plugin:compileKotlin
'compileJava' task (current target is 1.8) and 'compileKotlin' task (current target is 11) jvm target compatibility should be set to the same Java version.

This is the file in android/gradle/wrapper/gradle-wrapper.properties

I read similar posts but I haven't been able to fix it. With folders that I created some days ago I have no problem when I run the app.

Someone can help me please? Very thanks!

If you are using React Native witch Chocolatey, you must update JDK version to 11.
In order to do the update, execute this in PowerShell (with admin privileges):

choco install -y openjdk11

After that, the first time (only the first time) you run npm android, you will get a lot of warnings, but the built of the project will work.

If you continue receiving an error, maybe you need to adjust the gradle version of your project to be compatible with the new JDK version.
You can achieve this by editing the file YOUR_PROJECT\android\gradle\wrapper\gradle-wrapper.properties
Update the version of distributionUrl to 7.4.2

I hope I have been helpful

Android Gradle plugin requires Java 11 to run. You are currently using Java 1.8.

Ultimately you need a newer version of Java to run this. There are many resources online to assist you with this. As it is recommending Java 11 I would stick with that. One place to get Java 11 for Windows is on the Oracle downloads site (as you currently have the Oracle build) but there are others related to OpenJDK too.

I was having this very same problem here. I tried MouTio's solution and updated the distributionUrl to 7.4.2 at Project-Name\android\gradle\wrapper\gradle-wrapper.properties but that still gave me this error here:

> Task :react-native-gradle-plugin:compileKotlin FAILED

'compileJava' task (current target is 1.8) and 'compileKotlin' task (current target is 11) jvm targeta version. 1 actionable task: 1 executed

What went wrong: Execution failed for task ':react-native-gradle-plugin:compileKotlin'.

Failed to query the value of task ':react-native-gradle-plugin:compileKotlin' property 'compilerRun Kotlin could not find the required JDK tools in the Java installation. Make sure Kotlin compilat

However the error was fixed after running this choco install -y nodejs-lts openjdk11 with a command line using administration privileges.

and don't forget to run npm run android with a refreshed terminal.

The message is gone at last.

Before to that do the following [ iam using Mac]

Have JDK11 installed and HOME set
If you have any old version or have installed latest 18 and not as mentioned in the error. Then follow this URL to remove the the installation and ensure the path is set properly by following this [refer to the highest scored one]
Now to set the path follow this URL. Written by Arv
Now look for this file in android folder android/.idea/compiler.xml and change the target set as "1.8" to "11"
run ./gradlew clean [run it twice..else same message will be visible]
