I've got a Java web application that builds with Maven. My project uses RequireJS. I use a maven plugin at build time to compress the JS artifacts (https://github.com/bringking/requirejs-maven-plugin). The plugin calls out to NodeJS (with the r.js compressor) to do the actual work.
Local builds work wonderfully.
On Heroku, however, NodeJS is not available using the Heroku Java buildpack (the default for Java/Maven applications).
For now, I run the requireJS maven plugin locally using an active Maven profile that isn't present on the Heroku server. This prevents the RequireJS plugin from running on the Heroku server. This is less than ideal because it requires me to run the plugin locally, then check in the resulting build artifact. It's far better to generate the compressed JS file at build time in the Heroku system.
I'm looking for a good solution. Thanks in advance.
The best solution is to use Heroku Multi Buildpack with the Node.js and Java buildpacks. This is described in an article using Grunt with Java and Maven but the same principles apply for Require.js.

I am kind of struggling with transitioning from Jenkins to Travis-CI. Running an Appium (or consider it Selenium) project that is built using Maven. I am not sure what really should go into the travis.yml file. From what I have been told I need to do a before_install, before_script, and script, and after (after not sure). Could someone please be nice of kind enough to paste a travis.yml that was created for Java Maven project.
Also not sure I will get the test running on a physical device for a tool that is hosted on the Cloud. For Jenkins all we would do is hook up the device to the master/slave.
I'm new to Angularjs and i'm trying to run first angular program with Spring. I downloaded the code from here: http://javahonk.com/spring-mvc-angularjs-integration/. Imported it as a maven project. Downloaded JSDT and AngualrJs plugin from eclipse marketplace but it's still not running. There is no error message. I'm running this on tomcat 7. What am I missing?
Any help would be appreciated?
I'm not a Eclipse user. so I have no idea for that. But you can use nodejs as a static server. it is explained here
1) Install nodejs for your OS
2) Run this command in a terminal (console)
> npm install http-server -g
3) Start server
> cd /path/to/your/project
> http-server -o --cors
Now you can access your project from browser http://localhost:8080/yourfile.html
Work in Eclipse and just refresh page on browser to see changes.
If you are working on a Spring Application within Eclipse IDE, your best alternative would be to start you appliction using an embedded Application Server (Best I would recommand are Jetty or Tomcat if you ain't need EE level components).
You can follow this link, which holds basic steps for adding a new Application Server within Eclipse IDE.
Once you have added a new application server, you can deploy your application in it then launch it and you should have your applcation reachable at http://localhost:8080/SpringMVCAngularJS.
A good alternative when using Maven as a build tool, is using an embedded AS plugin such as Tomcat7 Plugin or Jetty Plugin. This plugin will provide the ability to start your applcation using the Maven different goals (which does not require adding a new AS into Eclipse IDE).
I've pushed a sample module based on the tutorial you mentioned. YOu can test the above described plugin as follows in a *nix shell (You may need to setup git if not already done):
git clone https://github.com/tmarwen/stackoverflow-showcase.git
cd stackoverflow-showcase/springmvc-angularjs
mvn tomcat7:run
I have a Java web application that I have managed to successfully deploy and get running on Heroku using the 'git push heroku master' method, but I would like to automate deployment and have a full CI setup. I've had a go at using Atlassian Bamboo with the Heroku plugin but it's really only suitable for standalone .war files - I need to be able to specify additional config via the Procfile definition in my project.
What have other people used for CI/CD of Java web applications to Heroku?
Jenkins has a good Heroku Plugin, that allow you to deploy WARs and interact with Heroku in many ways, including setting variables, scaling your dynos and running one-off processes:
https://github.com/heroku/heroku-jenkins-plugin/blob/master/README.md
To change the Procfile on Heroku, you need to commit and push the new file. You can do that as a step on your CI build. Jenkins can run scripts as part of your build, where you could easily push a new Procfile if that is needed.
we recently migrated to Maven Build manager & git hub repository for our Java web-app. Also i switched to eclipse as eclipse has good set of plugins.
As a new bie, i am simply running mvn clean package from terminal at the code root directory. And then moving the compiled code i.e., /target/SNAPSHOT/* to tomcat/webapps/ROOT location.
And then starting Tomcat7 server. The process is time taking especially when i do code changes in Java & configuration .xml files.
I want to do it completely in IDE environment as i did earlier in Netbeans, update code -> build and run in debug mode, -> do code changes and then commit.
Heard of egit & m2e in eclipse for maven & github integration, but not sure how to use it.
Please walk me through the steps required in doing so. I am completely new to eclipse.

You might want to consider using maven-jetty-plugin http://docs.codehaus.org/display/JETTY/Maven+Jetty+Plugin for running the webapp. You will not need to copy over stuff to tomcat. After configuring this plugin, you can simply run your application by doing mvn jetty:run
I generally do not like running webapps inside Eclipse. It's a personal prefrence, but it is always nice to have an IDE neutral way of building and running your applications. If you have m2e things should work simply fine. I have seen maven-jetty-plugin having hot pluggability where if you changed your web.xml, jetty would reload your application.
We use Git for version control and Maven for dependency management and build automation. Once your project has successfully imported into Eclipse and recognized as a valid java web project, you don't need either Git or Maven in order to build/run it inside IDE. Just creat a server using you existing tomcat installation, add the project to server, then select Run as > Run on Server.

I'm looking for a tool to run java server processes as daemon services in Linux (and potentially on Windows and other OS's). I'm looking for the best practices when it comes to how to build production capable scripts and launch configuration.
I'm familiar with best practices when it comes to a project's build, using Apache Maven, or something like Apache ANT + Ivy to manage your build process and manage external dependencies and build artifacts and assemblies.
When it comes to creating a project's assembly containing configuration and launch scripts along with all the compiled code and dependencies I'm unclear what the best choice is. Is there a good open source project that I could look at as an example, that bundles a service wrapper and configuration scripts with their build process?
I've been able to use Maven with the Jetty Launch plugin to run my Web applications, Terracotta Maven plugin to test multiple JVM clustered server nodes and I've used Maven's exec:java to run my custom Java servers, but I'm not sure using Maven in that capacity is really "production" quality, also it means my production servers depend on building the servers from source and downloading dependencies from potentially unavailable servers.
Here are some potential things I'm looking for in a Java service launcher solution:
Should run as a Linux service or Windows service process
Can be built using a Maven plugin or Ant script and allow me to process configuration files and scripts
Should be able to include all my project's dependencies from Apache Ant
Should be able to pull in a full Java Web Application server (e.g. Jetty 7) and be configured with my custom Web application's war
Should be able to handle a standard Java daemon service (custom java server)
Some of the options I've been looking at are Java Service Wrapper, which is used in the Maven appassembler plugin.
Also using Maven's assembly plugin and custom assembly descriptors allows me to tailor the build output.
The Java Service Wrapper seems to be quite common. I've seen it used by a few people, most notably in nexus.
The preferred (aka "best practice") way to implement Linux services of all kinds is to create a shell script that can start, stop and restart the service and put it into /etc/init.d. Then add appropriately symlinks to it from the relevant "rc.*" directories. Refer to the Linux "man" entries for "init(8)", "chkconfig(8)" and so on.
