ionic-cli: Requirements check failed for JDK 1.8 or greater

1.Remove all the Java related packages (Sun, Oracle, OpenJDK, IcedTea plugins, GIJ):

dpkg-query -W -f='${binary:Package}\n' | grep -E -e '^(ia32-)?(sun|oracle)-java' -e '^openjdk-' -e '^icedtea' -e '^(default|gcj)-j(re|dk)' -e '^gcj-(.*)-j(re|dk)' -e '^java-common' | xargs sudo apt-get -y remove
sudo apt-get -y autoremove

2.Purge config files (careful. This command removed libsgutils2-2 and virtualbox config files too):

dpkg -l | grep ^rc | awk '{print($2)}' | xargs sudo apt-get -y purge

3.Remove Java config and cache directory:

sudo bash -c 'ls -d /home/*/.java' | xargs sudo rm -rf

4.Remove manually installed JVMs:

sudo rm -rf /usr/lib/jvm/*

5.Remove Java entries, if there is still any, from the alternatives:

for g in ControlPanel java java_vm javaws jcontrol jexec keytool mozilla-javaplugin.so orbd pack200 policytool rmid rmiregistry servertool tnameserv unpack200 appletviewer apt extcheck HtmlConverter idlj jar jarsigner javac javadoc javah javap jconsole jdb jhat jinfo jmap jps jrunscript jsadebugd jstack jstat jstatd native2ascii rmic schemagen serialver wsgen wsimport xjc xulrunner-1.9-javaplugin.so; do sudo update-alternatives --remove-all $g; done

6.Search for possible remaining Java directories:

sudo updatedb
sudo locate -b '\pack200'

7.Install JAVA-8-SDK

sudo add-apt-repository ppa:webupd8team/java
sudo apt-get install oracle-java8-installer

8.Open sudo gedit ~/.bashrc and add these lines

export ANDROID_SDK_ROOT=/yourAndroidStudioPath/Android
export PATH=${PATH}:$ANDROID_SDK_ROOT/tools:$ANDROID_SDK_ROOT/platform-tools
export JAVA_HOME=/usr/lib/jvm/java-8-oracle
export JRE_HOME=/usr/lib/jvm/java-8-oracle/jre

Try to run your ionic app again 😃 Njoy!

*** IF YOU GET THIS ERROR ***

This error occurs when building Android projects for Cordova with Java 10. Cordova Android projects still require Java 8. The instructions for installing Java are different per OS.

Here are Cordova’s official instructions: https://cordova.apache.org/docs/en/latest/guide/platforms/android/index.html#java-development-kit-jdk

There are also plenty of online resources for installing Java 8. Just google something like "install java 8 mac os"

Same issue on Mac OS, solved by below code: export JAVA_HOME=$(/usr/libexec/java_home -v1.8)

Im working on a MacOS Mojave. I wasn’t been able to build for android with ionic. What i had to do was the following:

First of all, i had two versions of java. I removed them both, like so: cd /Library/Java/JavaVirtualMachines sudo rm -rf jdk<version_number>.jdk

I then went over to https://www.oracle.com/technetwork/java/javase/downloads/jdk8-downloads-2133151.html to download the jdk8 version, because ionic v3 apperently only supports this version.

After installing that i installed gradle because i didn’t had it at that moment: brew install gradle

An lastly i had to accept the License of the sdk, i could do it via the terminal like so: ~/Library/Android/sdk/tools/bin/sdkmanager --licenses and proceed the steps.

But i opened Android Studio, selected ‘SDK manager’ on the settings wheel at the bottom right corner and checked out the first three version of android (Android 9, 8.1, and 8.0). And proceeded the steps.

I restarted my terminal and ran the following command again: ionic cordova build android

And it worked! Hope this’ll help.

@dwieeb looks like the version check breaks with new java 10 versioning: /jdk-10.0.1.jdk is greater than 1.8

I’ve faced this problem, but now fixed, this is how…

I think it just about JDK setting on your ubuntu, make sure you install version 1.8 (manually from tar.gz, because ppa still not work).

then don’t forget to change default java & javac version into 1.8 with this

sudo update-alternatives --config javac
sudo update-alternatives --config java

Thank you @dwieeb i solved this by deleting the java 10 and install the java 8 once again… and i used brew to install the dpkg from the terminal.!

DUDE this is ore pure!, THANKS!!!

Fixed I just do edit ~/.bash_profile

export ANDROID_HOME=/Development/android-sdk/ export PATH=${PATH}:/Development/android-sdk/platform-tools:/Development/android-sdk/tools
