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

I faced similar error on an ubuntu machine while running a maven build from Jenkins. If output of 'javac -version' prompts below messages:

"The program 'javac' can be found in the following packages: default-jdk ecj gcj-5-jdk openjdk-8-jdk-headless gcj-4.8-jdk gcj-4.9-jdk openjdk-9-jdk-headless Try: apt install "

Then you can install "openjdk-8-jdk-headless" using:

apt install openjdk-8-jdk-headless

This solved my problem and the maven build went through ok.
