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

distributionUrl=https\://services.gradle.org/distributions/gradle-7.3.3-all.zip

and this is the output when I run ./gradlew --version

Kotlin:       1.5.31
Groovy:       3.0.9
Ant:          Apache Ant(TM) version 1.10.11 compiled on July 10 2021

OS:           Windows 10 10.0 amd64

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!

CodePudding user response：

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

CodePudding user response：

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.
