Having JAVA_HOME inconsistency issue with maven

Question

I am on the verge of releasing a project but it seem JAVA_HOME is been inconsistent. Maybe it\'s been overridden somewhere else? I am using ubuntu 14.04 and I have openjdk-7, ja

Answer 1

JAVA_HOME must point to jre, not jdk. Then set :

export JAVA_HOME=/usr/lib/jvm/java-8-oracle/jre

Answer 2

Another workaround:

export JAVACMD=$JAVA_HOME/bin/java

setting /usr/lib/jvm/java ⇒ /usr/java/jdk1.7.0_45 did not work for me

Answer 3

I spend quite some time to tackle similar error. It looks like package manager might create mess in Java installations. Path to Java is sometimes hardcoded in bash files. I found one in /etc/profile.d/jdk.sh. It just overrides your settings. Another fix/workaround for that is to update symlink, in my case it was /usr/lib/jvm/java ⇒ /usr/java/jdk1.7.0_45. Try to look for java/bin text in all bash files.

Answer 4

I had the same problem. My workaround was:

cd /usr/lib/jvm/java-8-oracle/jre/bin
sudo ln -s /usr/lib/jvm/java-8-oracle/bin/java java

I used OpenJDK as default java , updated JAVA_HOME in /etc/environment and all the issues went. Thanks for all your effort helping me through this
