to build CloudStack. A modern appliance based CloudStack development can be explored with MonkeyBox.
Use a Recent Eclipse Build
These steps have been tested with Eclipse Indigo and Eclipse Juno- it's suggested you use that or a newer build.
Start with a clean workspace
To minimize confusion, start with a clean workspace with no other projects.
Clone CloudStack via git
Download the CloudStack source code via git with:

CloudStack
Give Eclipse More Memory
CloudStack is a big project and it requires more memory for Eclipse. Here's how to give it more memory.
- cd [eclipse home]
- vi eclipse.ini
- Change or add the following properties
- -Xms1024m
- -Xmx2048m
- -XX:PermSize=512m
...
- -XX:MaxPermSize=1024M
...
Eliminate
...
duplicate
...
resources
...
CloudStack
...
has
...
a
...
lot
...
of
...
projects
...
that
...
are
...
really
...
just
...
for
...
grouping
...
the
...
different
...
type
...
of
...
projects.
...
The problem is in Eclipse,
...
the
...
files
...
that
...
belong
...
in
...
sub-projects
...
also
...
show
...
up
...
in
...
the
...
projects.
...
This causes a lot of problems with the Open Resource dialogue, which is often used to quickly get to a file if you know the filename already. These problems include the multiple copies of the same .class files showing up and multiple copies of the same .java file showing up. If you select the wrong .java file, then a lot of the references doesn't work. Upon further inspection, the reason is because the same .java and .class file is included by both the project and the parent project. To get rid of this problem, do the following. Unfortunately, you have to do this for every parent project.
- Right click on the project and select Properties.
- Go to Resource->Resource Filters.
- Click on Add...
- Select Exclude all
- Select Folders
- Click Regular Expression
- In the entry box, type [a-zA-Z0-9
...
- ].
...
- *
...
- Click
...
- OK
...
- Click
...
- OK
...
What
...
this
...
does
...
is
...
to
...
tell
...
Eclipse
...
that
...
the
...
sub-directories
...
under
...
parent
...
projects
...
should
...
not
...
be
...
included
...
in
...
the
...
resource
...
list,
...
thus
...
avoiding
...
the
...
the
...
duplicate
...
resources
...
in
...
the
...
Open
...
Resource
...
dialogue
...
box.
...
If the parent project does have a directory that you want, then you can add that to a include filter. Note that you can not use * as the folders because that would exclude the .settings folder which eclipse uses to keep its metadata and will cause the m2e plugin to have problems.
Here's a list of parent projects you should do this with:
- cloudstack
- cloudstack-framework
- cloudstack-plugins
- cloudstack-services
- cloud-engine
Avoiding conflicts between builds outside of Eclipse and Eclipse's auto-building
Eclipse by default uses the the Maven pom.xml to tell it where to put its generated files. Unfortunately, that has one big disadvantage. Everytime a "mvn clean" is done outside of Eclipse, Eclipse will start rebuilding. To avoid this, CloudStack has an Eclipse profile that puts all of the Eclipse generated files in a directory called target-eclipse. In order to activate this, you must do the following to every project. There is a shortcut for the existing projects so please read the shortcut first before deciding to do the following. You still need to perform these steps manually if a new project is added after you ran the shortcut.
- Right click on the project and select Properties
- Select Maven
- In the entry box under "Active Maven Profile", type in eclipse
- Click OK
CloudStack has a lot of projects so doing the above by hand for every project takes time so here's a shortcut provided for existing projects.
- Exit Eclipse (assuming you've already installed the m2e plugin)
- cd [cloudstack home]
- bash -x tools/eclipse/set-eclipse-profile.sh
...
- Restart Eclipse
Upgrading Java
CloudStack has requirement for a newer 1.7 JDK, the default on my Mac was 1.6. You need to download the latest JDK from Oracle JDK Download.
The installation on my Mac was not in the default location: /System/Library/Java/JavaVirtualMachines but in location: /Library/Java/JavaVirtualMachines/.
You can have multiple JRE/JDKs installed on your system, you need to add the path to the new JDK to Eclipse Preferences>Java>Installed JREs
For my JDK, the exact path I programmed was: /Library/Java/JavaVirtualMachines/jdk1.7.0_51.jdk/Contents/Home. Your path may be different depending on the current JDK version.
Bonus Track: Running CloudStack Through Eclipse
The Maven integration makes it reasonably easy to run and debug CloudStack through Eclipse. Basically, you can add the 'mvn' command-line calls to your Eclipse Workspace by defining corresponding Run Configurations.
The Maven commands we want to add as Run Configurations are discussed in detail on the How to build CloudStack page. The steps we want to add can be summarised as
- Clean (remove previous versions of source).
- Install (build new version of source)
- Database Setup (deploy a database with default settings, e.g. default password)
- Jetty-based server launch (Jetty is an alternative to Tomcat suited to development)
Now, we could have combined steps 1 & 2 above, but splitting them allows incremental compilation. In contrast, combining them will make for a very slow build. Also, you only need to setup the database once after doing a Clean.
WRT to debugging: Use the Jetty-based server lauch. First, tweak this Debug Configuration for source-level debugging: Use Run -> Debug Configurations, and check the Resolve Workspace Artifacts flag.
Creating a Run Configuration
For each Run Configuration to be added:
- From menu bar, select Run -> Run Configurations...
- Double click on Maven Build. This will create a Maven run configuration with the name New_configuration
- Update the Name to something corresponding to what happens in the step, and set Base Directory to
$project_loc:cloudstack(This tells Eclipse that the base directory for execution is the folder with a _pom.xml_ that has an <artifactId> with the value cloudstack) - From each mvn command, place the -P argument in the Profiles: textbox, Add... any parameters expressed as key=value , and place the remainder of the command in the Goals: textbox.
Maven will download everything needed to run CloudStack with Jetty, build the code, and run the UI. You can connect to it via http://localhost:8080/client

Remote Debugging
You can use Eclipse to attach to the Management Server and debug CloudStack. You setup a Remote Debug Session (Run > Debug Configuration), connect to Port 8787. Typically you would use the project you want to debug as the target and include other projects that you need to debug, e.g. cloud-agent, cloud-api, cloud-core and cloud-server.
