java – Maven error :Perhaps you are running on a JRE rather than a JDK?-ThrowExceptions

Exception or error:

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,

[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.


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?

How to solve:

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.


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.


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


For me, it worked like following.
Please look at JAVA_HOME environment variable, whether it is pointing to JRE or JDK.?
If it pointed to JRE, you will face “Perhaps you are running on a JRE rather than a JDK” issue. if so change the path to JDK.

Modifying like this, it worked for me.

JAVA_HOME C:\Program Files\Java\jdk1.8.0_31


Problem statement = No compiler is provided in this environment. Perhaps you are running on a JRE rather than a JDK?


Please set the Environment variable like below to solve the issue

Variable name : JAVA_HOME

Variable Value : C:\Program Files\Java\jdk1.8.0_202

Variable name : M2_HOME

Variable Value : C:\Program Files\apache-maven-3.6.0

Moreover, Add Java and maven path in “System Variables” like below:

  1. C:\Program Files\Java\jdk1.8.0_202\bin
  2. C:\Program Files\apache-maven-3.6.0\bin


Add this configurations in pom.xml

<project ...>
                    <executable>C:\Program Files\Java\jdk1.7.0_79\bin\javac</executable>


Just adding more details on where to setup. Main reason would be the JAVA_HOME setup in the environment variable should be pointing to correct JDK location.

  1. Check System -> Advance System Settings
  2. Click on Environment variable
  3. Add variable JAVA_HOME -> “C:\Program Files\Java\jdk1.8.0_141;”
  4. Edit “path” -> append %JAVA_HOME%; to the existing text.


This is how i fixed my problem

right clik on the project > properties > Java Compiler (select the one you are using)

it was 1.5 for me but i have 1.8 installed. so i changed it to 1.8.. and voilla it worked!.


Check if /usr/bin has ‘javac’. If not you have installed JRE & have to install jdk dev version like “java-1.8.0-openjdk-devel.x86_64”


I had the same issue after installing the java-1.8.0-openjdk package on an AWS Linux AMI. The incorrect assumption I made, was that because the file ended in openjdk it would be the jdk version. This is not the case.

The openjdk install page explains everything clearly.

The java-1.8.0-openjdk package contains just the Java Runtime
Environment. If you want to develop Java programs then install the
java-1.8.0-openjdk-devel package.

If you’ve already installed the java-1.8.0-openjdk package, just leave it and the JAVA_HOME value if it’s working for the JRE and install the java-1.8.0-openjdk-devel package using yum install java-1.8.0-openjdk-devel -y.


I was facing the same issue. I needed to place the JDK before the JRE in PATH in order to resolve.


i am using centos and getting same error when run mvn command with goal, install. After some googling i have found the solution to run following command.

sudo yum install java-1.8.0-openjdk-devel


Here’s my automatic solution…

This will follow your javac executable’s symlink (setup by yum and/or alternatives --config java) backwards to find the JAVA_HOME. (Toss this in your in your /etc/profile):

export JAVA_HOME=$(readlink -f /usr/bin/javac | sed 's:/bin/javac$::')

If you wanted a stable path (refreshed on boot) launch something like this:

export JAVA_HOME=$(readlink -f /usr/bin/javac | sed 's:/bin/javac$::')
ln -sfn "${JAVA_HOME}" /usr/lib/jvm/jdk-current

I’m kinda shocked the latter still isn’t baked into alternatives.


Right click on your project folder (Maven one), select properties and from the properties window, again select Java Compiler and see what is selected against compiler compliance level and make sure that it is the same version as your jre. In my case I had 1.8 but 1.5 was selected against compiler compliance level. After selecting 1.8 the build was successful without this error.


I had the same error and I was missing the User variable: JAVA_HOME and the value for the SDK – “C:\Program Files\Java\jdk-9.0.1” in my case


I faced the issue even though JAVA_HOME was pointing to JDK. It took time to figure out why it was throwing the exception.

The issue was I set JAVA_HOME as admin user on my window machine. You need to add JAVA_HOME environment variable pointing to right JDK to your user profile environment variable settings.


For solving my issue on Linux don’t have a JDK, I just download the JDK and upload to the Linux server, and type:
tar xvf jdk-8u45-linux-x64.tar.gz


I was facing the same issue in eclipse maven project, all i did was
right click on the project
maven –> update project
or just press ALT+ F5


If the above solutions doesn’t work then try to place java path before maven in path of environment variable. It worked for me.


C:\Program Files\apache-maven-3.6.1-bin\apache-maven-3.6.1\bin
