I have set up a new Cloud 9 project and am trying to run my Google App Engine (Java) project. I set the project up as a custom template. I type the following command into the terminal to build my project.

marcmouallem@my-project:~/workspace (master) $ mvn appengine:devserver
[INFO] Scanning for projects...
[INFO] ------------------------------------------------------------------------
[ERROR] BUILD ERROR
[INFO] ------------------------------------------------------------------------
[INFO] Error resolving version for 'com.google.appengine:appengine-maven-plugin': Plugin requires Maven version 3.0
[INFO] ------------------------------------------------------------------------
[INFO] For more information, run Maven with the -e switch

Mainly concerned with the part that says ...

 Plugin requires Maven version 3.0

Looking at the version I get ...

marcmouallem@my-project:~/workspace (master) $ mvn --version
Apache Maven 2.2.1 (rdebian-14)
Java version: 1.7.0_65
Java home: /usr/lib/jvm/java-7-openjdk-amd64/jre
Default locale: en, platform encoding: UTF-8
OS name: "linux" version: "3.14.13-c9" arch: "amd64" Family: "unix"
marcmouallem@my-project:~/workspace (master) $

Is there anyway I can get Cloud 9 to use Maven 3?

  • Okay, so getting Google App Engine (Java) with maven to work with Cloud 9 is not so straight forward, although it seems possible. You get a sandbox workspace, powered by Docker Ubuntu containers, so you should be able to do anything you want. I'll post a full tutorial when I have it figured out. – Marc M. Jan 16 '15 at 00:36
  • A tutorial would be awesome. – Brady Dowling Jan 22 '15 at 09:51

Cloud9 workspaces are Ubuntu Docker containers so you can install Maven 3 the standard way (making sure to remove Maven 2 as well).

Checkout the manual installation if your current ubuntu can not install maven via common 'apt-get install maven'.

sudo apt-get update
sudo apt-get install maven

Make sure to remove maven 2 if your ubuntu is not fresh or if you were using maven 2 before:

sudo apt-get remove maven2

Update: Cloud9 now provides Google Cloud Platform workspaces that come with Maven, gcloud tools, and Google Cloud deployment built-in. This may not be perfect for you but could offer you an environment where Maven is already setup for you.

  • I got there, I just ran into other hurdles when deploying the dev sever. I'll update the post when I get around to it. – Marc M. Jan 22 '15 at 02:57
