Im having trouble assembling War

[cranejimmy3]

Hello, as the title says, I'm having trouble assembling war. All I'm doing is cloning acs-community-packaging from Github, cd into the root folder, and running mvn clean install. I have not modified any pom.xml. The error I'm getting is 

Failed to execute goal org.apache.maven.plugins:maven-war-plugin:3.2.3:war (default-war) on project content-services-community: Error assembling WAR: Problem creating war: Execution exception: Java heap space -> [Help 1}

Thank you.

os ubuntu 16.04

mvn 3.6.3

Hi @cranejimmy3,

Could it be as issue of not enough heap memory?  Have you set MAVEN_OPTS correctly?

HTH,

[cranejimmy3]

Thanks for the reply.

Regarding Maven, the only thing I did with maven was adding the path to ~/.bashrc.

export M2_HOME=/home/user/Downloads/maven
export PATH=${M2_HOME}/bin:bin${PATH}

And I'm not familiar with heap memory but this is what's available on my machine.

                   total        used        free      shared  buff/cache   available
Mem:         628176      468328       37444       13660      122404       35244

You need to set MAVEN_OPTS as suggested by @EddieMay 

Navigate to maven installattion's bin directory (<mavenInstallDirectory>/bin) and open your mvn file and add the following line:

export MAVEN_OPTS=-Xmx1024m

This will allow to specify java heap space based on your project needs. You can increase it depending on your case.

After making changes, close all terminals and start a new terminal to execute "mvn clean install"
