react-native: Upgraded JDK 16 react-native run android problem Gradle Complaining

Go fix this file in your app folder and your problems should be over.

code android/gradle/wrapper/gradle-wrapper.properties

change

distributionUrl=https\://services.gradle.org/distributions/gradle-6.7-all.zip

to

distributionUrl=https\://services.gradle.org/distributions/gradle-7.1.1-all.zip

@dangolbeeker I think you had a typo when changing this file

@dangolbeeker Try this. No need to downgrade anything.

in my case Just changed gradle version in gradle-wrapper.properties to 7.2 or latest version of gradle like this :

distributionUrl=https://services.gradle.org/distributions/gradle-7.2-all.zip

and adding the following line in gradle.properties:

org.gradle.jvmargs=-Xmx1536M --add-exports=java.base/sun.nio.ch=ALL-UNNAMED --add-opens=java.base/java.lang=ALL-UNNAMED --add-opens=java.base/java.lang.reflect=ALL-UNNAMED --add-opens=java.base/java.io=ALL-UNNAMED --add-exports=jdk.unsupported/sun.misc=ALL-UNNAMED

this crispy stuff really make people life difficult, so damn annoying

Well this issue needs to fixed asap. I really don’t want to downgrade.

@sameem420 this works for me … Thanks!

here is a tip, you can change your current JAVA_HOME variable, i was having the same error, but it was because i had java JDK 16 and JDK 1.8. use JDK 1.8, and that is it. If you have a mac, here is an artice https://medium.com/@devkosal/switching-java-jdk-versions-on-macos-80bc868e686a

Another possibility is to modify the gradlew script to set the JAVACMD variable yourself. It could be as simple as removing all the JAVA_HOME and AIX tests and setting JAVACMD to the full path to the java binary.

In my case, I wanted something that’s not tied to my system, so I can push to our team’s repo, so I’m checking if a java.local symlink exists, and use that if it does. Otherwise, everything is how it was. (java.local points to /usr/lib/jvm/java-11-openjdk/bin/java on my system).

else
    # If there is a "java.local" executable (or link), use that instead.
    if [ -x "./java.local" ]; then
        JAVACMD="./java.local"
    else
        JAVACMD="java"
        which java >/dev/null 2>&1 || die "ERROR: JAVA_HOME is not set and no 'java' command could be found in your PATH.

Please set the JAVA_HOME variable in your environment to match the
location of your Java installation."
