Hi, I’m trying to run my React app Turn on via command

sudo React-Native run-android

But always returns me the following error message:

FAILURE: Build failed with an exception.

* What went wrong:
Could not determine java version from '11'.

I’ve tried to do everything

1- I tested my java version

java -version

openjdk version "11" 2018-09-25
OpenJDK Runtime Environment (build 11+24-Ubuntu-118.04)
OpenJDK 64-Bit Server VM (build 11+24-Ubuntu-118.04, mixed mode, sharing)

2- I included JAVA_HOME, both in /etc/enviroment and ~/. bashrc

echo $JAVA_HOME

/usr/lib/jvm/java-11-openjdk-amd64

I really don’t know what else to do, because apparently the whole environment is prepared to work properly.

java react react-native

  • Only appears this error ? Or you only took a part ? If possible edit the question and enter the full log. Apparently this error is related to Gradle.

Good! so you can upgrade Gradle to see if it’s compatible with Openjdk 11

But I recommend using oracle jdk 8 :

1 - Remove your open JDK 11 (if based on debian: apt purgue --remove openjdk*

2 - download Oracle JDK from SUN : https://www.oracle.com/technetwork/pt/java/javase/downloads/jdk8-downloads-2133151.html

3 - Unzip with : tar -zxvf

4 - Add to your PATH: vim ~/. bashrc export JAVA_HOME="/local/do/JDK/jdk1.8.0_181" export CLASSPATH="$JAVA_HOME/lib":$CLASSPATH export PATH="$JAVA_HOME/bin":$PATH export MANPATH="$JAVA_HOME/man":$MANPATH

And after editing : source ~/. bashrc

5 - Some cases of java error, see java -version Just follow this tip : https://www.vivaolinux.com.br/topico/Java/O-java-apresenta-um-erro-Preciso-de-ajuda

After that the java will be in version 8 , and recommended for use .
