*+This document is a work in progress and subject to change.+*

In order to build JBoss Tools in your workspace (or on your local machine, if not in Eclipse), you need to have its dependencies available. There are a number of ways to accomplish this, depending on your needs and how much manual effort you'd like to expend.

First, you'll need the JBoss Tools sources on disk. Fetch sources from trunk (or another branch) into ~/tru (or another location on disk).

svn co  http://anonsvn.jboss.org/repos/jbosstools/trunk/ http://anonsvn.jboss.org/repos/jbosstools/trunk/ ~/tru

Next, you can either install the target platform update site into your Eclipse install, or simply let Tycho fetch all the dependencies into a local m2 cached repository.

*------------------------------*
*
*
*OPTION 1: Let Tycho Resolve Dependencies From Remote Repo Into Local Cache
*

In this case, you don't even need Eclipse installed - you just need the sources on disk.

You will of course need  http://maven.apache.org/download.html Maven 3 installed.

a) Build parent + target platform poms (should only take a few mins; includes 18M of downloaded artifacts into your local Maven cache, eg., ~/.m2).

cd ~/tru/build; mvn3 clean install -f  http://anonsvn.jboss.org/repos/jbosstools/trunk/build/parent/pom.xml parent/pom.xml 

 b) Build one or more components (when done, ~/.m2 will be 1.1G in size):

cd ~/tru/build; mvn3 clean install +-U -B -e -fae -Dmaven.test.skip+ *-P helios-remote-target*
 *or*
cd ~/tru/build; mvn3 clean install +-U -B -e -fae -Dmaven.test.skip+** *-P helios-remote-target* *+-P seam-bootstrap+*

The 'helios-remote-target' will fetch the latest dependencies from this update site:

 http://download.jboss.org/jbosstools/updates/target-platform/latest/ http://download.jboss.org/jbosstools/updates/target-platform/latest/

If you omit the 'helios-remote-target' profile, you will instead use  http://anonsvn.jboss.org/repos/jbosstools/trunk/build/target-platform/unified.target unified.target to resolve specific versions of features/plugins, rather than the lastest available.

If you install  http://m2eclipse.sonatype.org/ m2eclipse, you can also start mvn3 builds from within Eclipse.

*------------------------------*
*
*
*OPTION 2: Let Tycho Resolve Dependencies From Local Repo Into Local Cache*
*
*
** If have a local Target Platform repo already mirrored on disk (for example, you  http://download.jboss.org/jbosstools/updates/target-platform/ downloaded a zip of the above update site and unpacked it somewhere, you can use the 'helios-local-target' profile.

You will of course need  http://maven.apache.org/download.html Maven 3 installed.

a) Edit the  http://anonsvn.jboss.org/repos/jbosstools/trunk/build/parent/pom.xml parent/pom.xml to point to the correct path on disk, and rebuild it. (The default path is the one that Hudson uses.)

vi parent/pom.xml # search for 'helios-local-target'
mvn3 clean install -f parent/pom.xml

b) Build using the 'helios-local-target' profile you modified to point to the correct location on your disk.

cd ~/tru/build; mvn3 clean install +-U -B -e -fae -Dmaven.test.skip+ *-P helios-local-target * 
*or+
+*
cd ~/tru/build; mvn3 clean install +-U -B -e -fae -Dmaven.test.skip+ *-P helios-local-target +-P seam-bootstrap+*

This is how the Hudson builds run: compile the parent & target platform pom.xml files, then build the desired component(s) against a locally available update site.

If you omit the 'helios-local-target' profile, you will instead use  http://anonsvn.jboss.org/repos/jbosstools/trunk/build/target-platform/unified.target unified.target to resolve specific versions of features/plugins, rather than the lastest available.

If you install  http://m2eclipse.sonatype.org/ m2eclipse, you can also start mvn3 builds from within Eclipse.

*------------------------------*

*OPTION 3: (DEPRECATED) Install Target Platform Update Site into Eclipse*

Point the latest Eclipse 3.6.x build at the  http://download.jboss.org/jbosstools/updates/target-platform/latest/ Target Platform update site (generated from this  http://anonsvn.jboss.org/repos/jbosstools/trunk/build/target-platform/e361-wtp322.target e361-wtp322.target file). Be sure to show uncategorized features, then install everything.

 http://download.jboss.org/jbosstools/updates/target-platform/latest/ http://download.jboss.org/jbosstools/updates/target-platform/latest/

After restarting Eclipse, you should have all the dependencies installed to develop JBoss Tools; however, if you want to use this Eclipse as the target platform against which to build using Tycho, you need to also unzip the latest  http://http//download.eclipse.org/eclipse/downloads/drops/R-3.6.1-201009090800/index.php#DeltaPack deltapack (eg., eclipse-M20101020-0925-delta-pack.zip) into your Eclipse root folder. Once you've done that, you can use the following commands to tell Maven (and Tycho) to use that Eclipse instead of doing its own resolution.

You will of course need  http://maven.apache.org/download.html Maven 3 installed.

a) Build parent + target platform poms (should only take a few mins; includes 18M of downloaded artifacts into your local Maven cache, eg., ~/.m2).

cd ~/tru/build; mvn3 clean install -f  http://anonsvn.jboss.org/repos/jbosstools/trunk/build/parent/pom.xml parent/pom.xml

 b) Build all components or use the bootstrap profiles in  http://anonsvn.jboss.org/repos/jbosstools/trunk/build/pom.xml build/pom.xml to build a stack of components, such as Seam:

cd ~/tru/build; mvn3 clean install +-U -B -e -fae -Dmaven.test.skip+ *-Dtycho.targetPlatform=/path/to/your/eclipse*
 *or*
cd ~/tru/build; mvn3 clean install +-U -B -e -fae -Dmaven.test.skip+ *-Dtycho.targetPlatform=/path/to/your/eclipse* *+-P seam-bootstrap+*

Note that if you install  http://m2eclipse.sonatype.org/ m2eclipse, you can also start mvn3 builds from within Eclipse.

Note that the use of *-Dtycho.targetPlatform=* is *DEPRECATED* and is planned to be removed from a future release of Tycho.

Checking the Target Platform To See What's There
There are three ways to see what's already in the Target Platform. (This can be useful if you're checking to see if something's already there or needs to be added.)

Option 1:

1. In Eclipse, go to Help->Install New Software...
2. Provide the URL:  http://download.jboss.org/jbosstools/updates/target-platform/latest/ http://download.jboss.org/jbosstools/updates/target-platform/latest/
3. Click Add and give it a useful name such as "Current JBoss Tools Target Platform"
4. Browse the list of features. Note that you may have to uncheck the "Group Items By Category" checkbox.

Option 2:

Explore the file  http://anonsvn.jboss.org/repos/jbosstools/trunk/build/target-platform/multiple.target http://anonsvn.jboss.org/repos/jbosstools/trunk/build/target-platform/multiple.target or  http://anonsvn.jboss.org/repos/jbosstools/trunk/build/target-platform/unified.target http://anonsvn.jboss.org/repos/jbosstools/trunk/build/target-platform/unified.target in an XML editor or Eclipse's Target Platform editor

Option 3:

Explore the file  http://anonsvn.jboss.org/repos/jbosstools/trunk/build/target-platform/multiple.target.p2mirror.xml http://anonsvn.jboss.org/repos/jbosstools/trunk/build/target-platform/multiple.target.p2mirror.xml or  http://anonsvn.jboss.org/repos/jbosstools/trunk/build/target-platform/unified.target.p2mirror.xml http://anonsvn.jboss.org/repos/jbosstools/trunk/build/target-platform/unified.target.p2mirror.xml. This file is the same as its matching target file but as an Ant script. It does not contain feature/plugin versions, just repo URLs and a list of IUs (feature.group == feature + contained plugins). It is therefore instructions for how to download the contents of the .target file onto your local disk. You can run it using `ant -f multiple.target.p2mirror.xml` or using the  http://anonsvn.jboss.org/repos/jbosstools/trunk/build/target-platform/build.xml build.xml script in the  http://anonsvn.jboss.org/repos/jbosstools/trunk/build/target-platform/ same folder.
