I get the following errors -<

Answer 1

The possible reason is the Gradle 's version and JDK's version is not matched.

At begin, My computer's gradle version is 4.10.1 and JDK is 12.

My solution is:

Download JDK 1.8 from oracle's website, set JAVA_HOME with JDK8 and It done

Answer 2

I encountered this error while running the following command in macOS

./gradlew assembleRelease --stacktrace

and got the exact error posted. I solved the problem by setting $JAVA_HOME environment variable to your JDK installation. In my case I used the bundled JDK in Android Studio for macOS:

export JAVA_HOME="/Applications/Android Studio.app/Contents/jre/jdk/Contents/Home"

for Windows, just add JAVA_HOME to your user or system variables pointing to

"C://Program Files/Java/jdk_1.x_"

folder and try running react-native run-android again.

On Ubuntu 18.04, this fixed the problem.

1. Run this command

   sudo apt-get install openjdk-8-jdk

2. Add this to ~/.bashrc

   export JAVA_HOME="/usr/lib/jvm/java-8-openjdk-amd64"

3. Restart your terminal or IDE.

Answer 4

this because your classpath build tools in build.gradle root project is deprecated update like this for new android studio 3.1.2

buildscript {
    repositories {
        jcenter()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:3.1.2'
    }
}

and after that update your minimum sdk and build tools to latest and no problem again

Answer 5

Fixed the error by adding the following in .bash_profile

 export JAVA_HOME=/Library/Java/JavaVirtualMachines/jdk1.8.0_171.jdk/Contents/Home
export PATH=$PATH:$JAVA_HOME/bin
export ANDROID_HOME=/Users/saif-ams/MyFiles/applications/androidsdk
export PATH=$PATH:$ANDROID_HOME/tools:$ANDROID_HOME/platform-tools

Answer 6

This is a problem with JDK version 9. Android tools does not support building with Java 9 officially yet. And it has such problems.

Downgrading to Java version 8 will fix the problem.
