The org.eclipse.releng.basebuilder project 21 contains the minimal set of plug-ins extracted from the latest stable Eclipse 22 3.2 stream SDK build (a milestone or release) needed to run applications and custom 23 Ant tasks in org.eclipse.ant.core, org.eclipse.pde.build, org.eclipse.pde, and 24 org.eclipse.help.base. This project is used by the Eclipse release engineering 25 team to build Eclipse itself. <P>It is assumed the reader is starting with a set 26 of pre-existing features and plug-ins, their build.properties, and has a working 27 knowledge of Apache Ant. In this document, features, plug-ins and fragments are 28 also referred to as "elements". The word "distribution" is 29 used to describe the end result of building a feature, a functional unit comprised 30 of one or more groupings of plug-ins. The result of building a feature results 31 in a zip or tar.gz file which contains the binary version of the feature and it's 32 plug-ins. If the feature contains nested features (i.e. <includes> elements), 33 the nested features will be built recursively and included in the distribution.<br> 34 <br> For example, the Eclipse SDK distributions are built from the <a href="http://dev.eclipse.org/viewcvs/index.cgi/%7Echeckout%7E/org.eclipse.sdk-feature/feature.xml?rev=1.7" target="extra">org.eclipse.sdk 35 feature</a> which is comprised of features org.eclipse.rcp, org.eclipse.rcp.source, 36 org.eclipse.platform, org.eclipse.platform.source, org.eclipse.jdt, org.eclipse.jdt.source, 37 org.eclipse.pde, org.eclipse.pde.source and the org.eclipse.sdk plug-in. The distribution 38 built from the org.eclipse.sdk feature will therefore contain the binary version 39 of the org.eclipse.sdk feature and its one plug-in plus the binary versions of 40 its eight nested features and all their plug-ins.<br> <br> <HR><P><FONT SIZE="+2"><B><A NAME="preparation"></A>Preparing 41 the infrastructure</B></FONT></P><P><B><FONT SIZE="+1" COLOR="#000000"><A NAME="commit"></A>Commit 42 feature and plug-in projects to CVS repository</FONT></B></P><P>Since Eclipse 43 3.0, PDE Build allows a very flexible organization of feature, plug-in and fragment 44 projects in a CVS repository where:</P><UL> <LI> the directory containing the 45 source for an element can exist as a root level CVS module or in any subdirectory 46 in the repository.</LI><LI>the directory name containing the element's source 47 does not have to match the id attribute in it's manifest (feature.xml, plugin.xml, 48 fragment.xml).</LI></UL><P>This flexibility was not present for the Eclipse process 49 prior to version 3.0 which is one reason for the very flat organization of projects 50 in the dev.eclipse.org:/home/eclipse repository.
