Error: Requirements check failed for JDK 1.8 or greater on Ionic

Question

I have an Ionic app which started to fail when I run:

ionic cordova run android --consolelogs --device --livereload

I get this error:

ANDROID_HOME=/home/ivan/Android
JAVA_HOME=/usr/lib/jvm/java-10-oracle/
Error: Requirements check failed for JDK 1.8 or greater

My environment variables are:

echo $JAVA_HOME
/usr/lib/jvm/java-10-oracle/

echo $ANDROID_HOME
/home/ivan/Android

My current versions:

java -version
java version "10.0.2" 2018-07-17
Java(TM) SE Runtime Environment 18.3 (build 10.0.2+13)
Java HotSpot(TM) 64-Bit Server VM 18.3 (build 10.0.2+13, mixed mode)

javac -version
javac 10.0.2

Ionic info:

Answer 1

Well, I solved this issue with the following steps:

I had the v10 of java's sdk. So I downgraded to v8.

• Uninstall my jdk with: sudo apt-get remove oracle-java10-installer

• Follow this steps to install v8.

• Restored my global installation of cordova. It was in 8.0.0 and I restored it to 7.0.1 with the command: sudo npm install -g cordova@7.0.1 .

• I restored my "cordova-android": to "^6.4.0" (in my app),

• Deleted all the plugins in confix.xml.

• Deleted android platform: ionic cordova platform remove android .

• Remove dependencies and plugins: rm -rf /node_modules /plugins .

• Add android platform again: ionic cordova platform add android .

• Then run on device: ionic cordova run android --consolelogs --device --livereload .
