Maven error :Perhaps you are running on a JRE rather than a JDK?

I've never worked with Maven before and I am following the instructions here. When I run the command

mvn integration-test -Pamp-to-war

It initially downloaded a whole bunch of dependencies, and in the end it showed,

COMPILATION ERROR : 
[INFO] -------------------------------------------------------------
[ERROR] No compiler is provided in this environment. Perhaps you are running on a JRE rather than a JDK?
[INFO] 1 error

I am on ubuntu 13.04.

If there's anything you want me to tell you, let me know. Thanks.

EDIT

When I do echo $JAVA_HOME I get /usr/lib/jvm/java-7-openjdk-i386/

When I do mvn -version

I get,

Apache Maven 3.0.4
Maven home: /usr/share/maven
Java version: 1.7.0_25, vendor: Oracle Corporation
Java home: /usr/lib/jvm/java-7-openjdk-i386/jre
Default locale: en_US, platform encoding: UTF-8
OS name: "linux", version: "3.8.0-26-generic", arch: "i386", family: "unix"

Also, I found out this problem faced by someone else. But I am not sure how to go about the solution that is specified?

Solution 1:

I've been facing the same issue with java 8 (ubuntu 16.04), trying to compile using mvn command line.

I verified my $JAVA_HOME, java -version and mvn -version. Everything seems to be okay pointing to /usr/lib/jvm/java-8-openjdk-amd64.

It appears that java-8-openjdk-amd64 is not completly installed by default and only contains the JRE (despite its name "jdk").

Re-installing the JDK did the trick.

sudo apt-get install openjdk-8-jdk

Then some new files and new folders are added to /usr/lib/jvm/java-8-openjdk-amd64 and mvn is able to compile again.

Solution 2:

Apparently, it requires tools.jar file inside the lib folder of my $JAVA_HOME. I did not have the lib folder, so I reinstalled my jdk using command

apt-get install openjdk-7-jdk openjdk-7-doc openjdk-7-jre-lib

Also, this link may help some people.

Solution 3:

This is because of running jre rather than jdk, to install jdk follow below steps

Installing java 8 in amazon linux/redhat

--> yum search java | grep openjdk

--> yum install java-1.8.0-openjdk-headless.x86_64

--> yum install java-1.8.0-openjdk-devel.x86_64

--> update-alternatives --config java #pick java 1.8 and press 1

--> update-alternatives --config javac #pick java 1.8 and press 2

Thank You
