This article is a replacement for its precursor, How to Build JBoss Tools 3.2 with Maven 3.
Note that this article only discusses building from trunk. If you need to build from a branch, or switch between branches and/or trunk, see How to Build JBoss Tools With Maven3 - Working With Branches.

Environment Setup
Prerequisistes
- Java 1.6 SDK
- Maven 3.0.3
- About 6 GB of free disk space if you want to run all integration tests for (JBoss AS, Seam and Web Services Tools) - requires VPN access
- subversion client 1.6.X (should work with lower version as well, but newer versions may not work as expected)
Maven and Java
Make sure your maven 3 is available by default and Java 1.6 is used.
mvn -version
should print out something like
Apache Maven 3.0.3 (r1075438; 2011-02-28 12:31:09-0500)
Java version: 1.6.0_25, vendor: Sun Microsystems Inc.
Java home: /usr/java/jdk1.6.0_25/jre
Default locale: en_US, platform encoding: UTF-8
OS name: "linux", version: "2.6.42.3-2.fc15.x86_64", arch: "amd64", family: "unix"
Maven settings
Follow these instructions to add reference to JBoss Repositories into your settings.xml. You'll also probably need access to the SNAPSHOT repository. So here is what you should see in your ~/.m2/settings.xml

Maven & Java Memory Configuration
To configure the amount of memory used by Maven, you can define MVN_OPTS as follows, either in the mvn / mvn.bat script you use to run Maven, or set as global environment variables. Here's how to do so for Fedora, Ubuntu, Windows, OSX.
{code}
set MAVEN_OPTS=-Xms512m -Xmx1024m -XX:PermSize=128m -XX:MaxPermSize=256m
{code}
The target platform (TP) lists all dependencies (coming from Eclipse.or and other 3rd-party update sites) that are used by JBoss Tools. This target platform is materialized as an Eclipse p2 repository (formerly update-site) that is used during build to resolve dependencies. Target Platform is managed by JBoss Tools people, and only dependencies from this TP are allowed to be used in code.
If you need a new dependency in the TP, feel free to open a ticket to request it.
Here are several ways to build locally using this target platform. It's up to you to choose the one that match your needs:
Set up
Download TP as a zip and install it by yourself
You can either download the TP as a zip and unpack it into some folder on your disk. For convenience, the easiest is to unzip into jbosstools/build/target-platform/REPO/, since that's where the Maven or Ant process will by default operate.
You can get it with a browser or a command line tool such as wget or curl at the following url: http://download.jboss.org/jbosstools/updates/target-platform_3.3.indigo.SR2/<actualFilename>.target.zip
and then unzip it here (the default path for -Dlocal.site, which means you can call maven with -Plocal.site and not need to pass in -Dlocal.site=file:///path/to/some/other/folder/ as well):
unzip *.target.zip -d jbosstools/build/target-platform/REPO/
(Note that the default path used for <local.site> will change every time a new target platform is released which is a significant change over the previous (eg., SR1, SR2), so if this breaks because the default not points at an empty folder, it's time to get a new TP! Hurray for build-time notification you're using an old target platform!)
OR, use Maven+Ant to get it
In that case, you also need Ant 1.8.2 or later.
cd jbosstools/build/target-platform
mvn clean install -Pget.local.target
The get.local.target profile will resolve the target platform file, multiple.target, as a p2 repository on your local disk in ~/trunk/build/target-platform/REPO/. It may take a while, so you're better off from a speed point-of-view simply fetching the latest zip [5]. However, if you want to see what actually happens to create the TP (as done in Hudson) this is the approach to take.
Since the Maven profile is simply a wrapper call to Ant, you can also use Ant 1.8 or later directly:
cd jbosstools/build/target-platform
ant help # show usage instructions
Use
Just add -P local.site -Dlocal.site=file:///path/to/target/repository/
NOTE: You must specify a path starting with file:/// (three or more slashes) to avoid errors such as "p2.core.ProvisionException URI has an authority component".
Examples
LINUX / MAC USERS
cd build
mvn clean install -U -B -fae -e -P local.site -Dlocal.site=file:///${HOME}/trunk/build/target-platform/REPO/| tee build.all.log.txt
WINDOWS USERS
cd c:\trunk\build
mvn3 clean install -U -B -fae -e -Plocal.site -Dlocal.site=file:///C:/trunk/build/target-platform/REPO/ > build.all.log.txt
unified.target refers to the dependency as published in the Target Platfrom repository.
- Pros: No additional thing to do than invoking Maven
- Cons: Speed ---
Consume it by adding -Punified.target to you Maven invocation command-line
This step is only useful if you are actually working on the parent or the target platform and want to test it locally. Otherwise, Maven will simply retrieve parent and TP from JBoss Nexus to perform your build.
This is only necessary when the TP change, prior to 3.3.Beta3
svn co http://svn.jboss.org/repos/jbosstools/trunk jbosstools
cd jbosstools/build/parent
mvn clean install
...
[INFO] Reactor Summary:
[INFO]
[INFO] JBoss Tools Target Platform Definition ............ SUCCESS [0.724s]
[INFO] JBoss Tools Parent ................................ SUCCESS [0.461s]
...
NOTE: You need not fetch the entire JBoss Tools tree from SVN (or Git).
Instead, you can just fetch the build/ folder and one or more component folders, then as before,
build the parent pom. After that, go into the component folder and run maven there.
mkdir jbosstools
cd jbosstools
svn co http://svn.jboss.org/repos/jbosstools/trunk/build
svn co http://svn.jboss.org/repos/jbosstools/trunk/jmx
cd jbosstools/build/parent
mvn clean install

Building Everything In One Build Locally Via Commandline
Assuming you have a local copy of the target platform in ${HOME}/trunk/build/target-platform/REPO/ (as explained previously:
LINUX / MAC USERS
cd build
mvn clean install -P local.site -Dlocal.site=file:///${HOME}/trunk/build/target-platform/REPO/ | tee build.all.log.txt
(tee is a program that pipes console output to BOTH console and a file so you can watch the build AND keep a log.)
WINDOWS USERS
cd c:\trunk\build
mvn3 clean install -P local.site -Dlocal.site=file:///C:/trunk/build/target-platform/REPO/
or
mvn3 clean install -Plocal.site -Dlocal.site=file:///C:/trunk/build/target-platform/REPO/ > build.all.log.txt
If you downloaded the zip and unpacked is somewhere else, use -Dlocal.site=file:///.../ to point at that folder instead.

Building Individual Components Locally Via Commandline
Build a component resolving to a recent aggregation build for other JBT dependencies (Recommanded)
- Pros:
- You build only your component
- You only need source for your component
- Speed to resolve deps: +
- You get generally the latest build for you component
- Cons:
- Takes some time to resolve dependencies on other component
- Can sometimes be out of sync if no build occured recently for a component you rely on and had some important change. More risk to get out of sync than with the staging site.
Tracked by https://issues.jboss.org/browse/JBIDE-11516
cd jmx
mvn clean install -P local.site -Dlocal.site=file:///${HOME}/trunk/build/target-platform/REPO/ -Pjbosstools-staging-aggregate
Build a component resolving to the latest CI builds for other JBT dependencies
- Pros:
- You build only your component
- You only need source for your component
- You get generally the latest build for you component
- Cons
- Takes some time to resolve dependencies on other component
- Can sometimes be out of sync if no build occured recently for a component you rely on and had some important change
- Speed to resolve deps: -
This profile is the one use for CI builds on Hudson.
cd jmx
mvn clean install -P local.site -Dlocal.site=file:///${HOME}/trunk/build/target-platform/REPO/ -Pjbosstools-nightly-staging-composite
Build a component along with all its dependencies from sources ("bootstrap" build)
This will build exactly what you have locally
- Pros:
- You are sure of the version of sources that is used for your JBT dependencies
- You don't loose time in resolving your JBT deps
- Cons:
- You need sources for your dependencies too
- You often build more stuff that what you really want to test
cd ~/trunk/build
mvn clean install -P local.site,jmx-bootstrap -Dlocal.site=file:///${HOME}/trunk/build/target-platform/REPO/ | tee build.jmx.log.txt
#
Building Locally In Eclipse
First, you must have installed m2eclipse into your Eclipse (or JBDS). You can install the currently supported version from this update site:
http://download.jboss.org/jbosstools/updates/indigo/
Next, start up Eclipse or JBDS and do File > Import to import the project(s) you already checked out from SVN above into your workspace.
https://community.jboss.org/servlet/JiveServlet/downloadImage/102-16604-46-13876/310-276/Screenshot.png
Browse to where you have the project(s) checked out, and select a folder to import pom projects. In this case, I'm importing the parent pom (which refers to the target platform pom). Optionally, you can add these new projects to a working set to collect them in your Package Explorer view.
https://community.jboss.org/servlet/JiveServlet/downloadImage/102-16604-46-13877/450-259/Screenshot-1.png
Once the project(s) are imported, you'll want to build them. You can either do CTRL-SHIFT-X,M (Run Maven Build), or right-click the project and select Run As > Maven Build. The following screenshots show how to configure a build job.
First, on the Main tab, set a Name, Goals, Profile(s), and add a Parameter. Or, if you prefer, put everything in the Goals field for simplicity:
clean install -U -B -fae -e -Plocal.site -Dlocal.site=file://home/nboldt/tmp/JBT_REPO_Indigo/
Be sure to check Resolve Workspace artifacts, and, if you have a newer version of Maven installed, point your build at that Maven Runtime instead of the bundled one that ships with m2eclipse.
https://community.jboss.org/servlet/JiveServlet/downloadImage/102-16604-46-13878/450-540/Screenshot-2.png
On the JRE tab, make sure you're using a 6.0 JDK.
https://community.jboss.org/servlet/JiveServlet/downloadImage/102-16604-46-13879/450-538/Screenshot-3.png
On the Refresh tab, define which workspace resources you want to refresh when the build's done.
https://community.jboss.org/servlet/JiveServlet/downloadImage/102-16604-46-13880/450-539/Screenshot-4.png
On the Common tab, you can store the output of the build in a log file in case it's particularly long and you need to refer back to it.
https://community.jboss.org/servlet/JiveServlet/downloadImage/102-16604-46-13881/450-542/Screenshot-5.png
Click Run to run the build.
https://community.jboss.org/servlet/JiveServlet/downloadImage/102-16604-46-13882/450-347/Screenshot-6.png
Now you can repeat the above step to build any other component or plugin or feature or update site from the JBoss Tools repo. Simply import the project(s) and build them as above.
Installation Testing - making sure your stuff can be installed
Each component, when built, produces a update site zip and an unpacked update site which can be used to install your freshly-built features and plugins into a running Eclipse or JBDS instance.
Simply point your Eclipse at that folder or zip, eg., jar:file:/home/rob/code/jbtools/jbosstools/trunk/runtime/site/target/runtime.site.zip! or file:///home/rob/code/jbtools/jbosstools/trunk/runtime/site/target/repository/, and browse the site. If your component requires other upstream components to install, eg., Runtime Detection depends on JBoss Common, you will also need to provide a URL from which Eclipse can resolve these missing dependencies. In order of freshness, you can use:
- http://download.jboss.org/jbosstools/updates/nightly/core/trunk/ (Nightly Trunk Site - updated every few hours or at least daily - bleeding edge)
- http://download.jboss.org/jbosstools/builds/staging/_composite_/core/trunk/ (Composite Staging Site - updated every time a component respins - bleedinger edge)
- http://anonsvn.jboss.org/repos/jbosstools/trunk/build/aggregate/local-site/ (see the README.txt for how to use this site to refer to things you built locally - bleedingest edge)
Adding a new feature or plugin to an existing component

Tips and tricks for making BOTH PDE UI and headless Maven builds happy
It's fairly common to have plugins compiling in eclipse while tycho would not work. Basically you could say that tycho is far more picky compared to Eclipse PDE.
Check your build.properties
Check build.properties in your plugin. If it has warnings in Eclipse, you'll most likely end with tycho failing to compile your sources. You'll have to make sure that you correct all warnings.
Especially check your build.properties to have entries for source.. and output.. -- these are needed to generate source plugins and features.
source.. = src/
output.. = bin/
src.includes = *
src.excludes = src
bin.includes = <your own,\
list of,\
files for inclusion,\
in the jar>
Check your manifest.mf dependencies
A new issue when building against juno shows that all compilation dependencies MUST be EXPLICITLY mentioned in your manifest.mf list of dependencies. A recent example of how this can cause compilation errors is the archives module, which failed to build due to the org.eclipse.ui.views plugin, and its IPropertySheetPage interface, not being found during the build. After investigation, it was discovered that the archives.ui plugin did not explicitly declare a dependency on org.eclipse.ui.views.
Inside eclipse and during indigo builds, however, the depencency was found and there were no compilation errors. This was because a plugin archives.ui explicitly dependend on (org.eclipse.ui.ide) had an explicit dependency on org.eclipse.ui.views. The IDE was able to see that archives.ui dependended on org.eclipse.ui.ide, and org.eclipse.ui.ide depended on org.eclipse.ui.views.
Resolving nested dependencies no longer seems to be guaranteed, and so anything you have a compilation dependency on must now be explicitly declared in your manifest.mf.
