The application (Cocos2d-x) tells that

JAVA_HOME is set to an invalid directory: /usr/lib/jvm/java-1.9.0-openjdk-amd64

My /etc/environment contains this:

PATH="/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/usr/local/games"
JAVA_HOME=/usr/lib/jvm/java-1.8.0-openjdk-amd64
export JAVA_HOME

Content of ~./bashrc:

# Add environment variable ANT_ROOT for cocos2d-x
export ANT_ROOT="/usr/share/ant/bin"
export PATH=$ANT_ROOT:$PATH
JAVA_HOME="/usr/lib/jvm/java-1.8.0-openjdk-amd64"

Output of whereis java:

java: /usr/bin/java /usr/share/java /usr/share/man/man1/java.1.gz

Output of which java:

/usr/bin/java

Output of java -version:

openjdk version "1.8.0_151"
OpenJDK Runtime Environment (build 1.8.0_151-8u151-b12-0ubuntu0.16.04.2-b12)
OpenJDK 64-Bit Server VM (build 25.151-b12, mixed mode

ls /usr/lib/jvm gives this:

java-1.8.0-openjdk-amd64 java-8-openjdk-amd64

JDK itself works: I can compile Java programs and Android Studio's (non-cocos).

  • Run update-alternatives --list java and post the result – George Udosen Jan 6 '18 at 21:03
  • update-alternatives --list java /usr/lib/jvm/java-8-openjdk-amd64/jre/bin/java – R S Jan 7 '18 at 12:10
  • Please add ant additional info to your post, please check your cocos configuration perhaps your missing a configuration. – George Udosen Jan 7 '18 at 12:37
  • @George Udosen I already managed to install Java 9 properly or almost properly, there another problems now. I think this question is not actual for me anymore. Thank you. – R S Jan 7 '18 at 15:26

Two things:

  1. This line export JAVA_HOME should not be in /etc/emvironment, then make JAVA_HOME=/usr/lib/jvm/java-1.8.0-openjdk-amd64 this JAVA_HOME="/usr/lib/jvm/java-1.8.0-openjdk-amd64", and
  2. This JAVA_HOME="/usr/lib/jvm/java-1.8.0-openjdk-amd64" in ~/.bashrc should be replace with these lines:

    JAVA_HOME="/usr/lib/jvm/java-1.8.0-openjdk-amd64"
    export PATH=$PATH:$JAVA_HOME/bin

  • Thanks, but still the same. – R S Jan 6 '18 at 20:53
  • Did you do source ~/.bashrc after updating .bashrc file? – George Udosen Jan 6 '18 at 20:54
  • Yes, I did. And the same to /etc/environment. – R S Jan 6 '18 at 20:56
  • Hell no, man. After that edit I couldn't login. I removed JAVA_HOME and export lines from /etc/environment using liveCD and logged in then. – R S Jan 6 '18 at 21:56
  • I never said you should put export lines in /etc/environment sorry if you miss understood me. You edited two file and the second step was meant for the ~/bashrc file. – George Udosen Jan 6 '18 at 22:11
