Unable to locate the Javac Compiler

Question

I tried to mvn install and got this message:

Compilation failure
Unable to locate the Javac Compiler in:
  /usr/lib/jvm/java-7-openjdk-amd64/jre         


        

Answer 1

it seems like your PATH is not picked up correctly... does the output of "echo $PATH" contain the directory where javac resides? I would suggest following:

open terminal and do an:

export JAVA_HOME=/usr/lib/jvm/jdk1.7.0_03
export PATH=$PATH:$JAVA_HOME/bin
javac -version
which javac

if javac -version still does not work create a symlink in /usr/local/bin pointing to your javac binary:

cd /usr/local/bin
ln -s /usr/lib/jvm/jdk1.7.0_03/bin/javac javac

this should get you up an running... an alternative is to try setting up java via your package management system (e.g. "apt-get install java" or sth. similar)
