Running Eclipse Source builds for 3.5 (Source from CVS)

What is an Eclipse Source Build?

Eclipse source builds provide developers with an automated method for checking out source code and other required resources, compiling the Java code, generating javadoc, and finally, creating a zip file of an Eclipse runtime from a downloaded ource tree. The end result of a source build is a runnable Eclipse.

Getting the Source

A source build download contains shell and ant scripts that fetch and build a particular version of Eclipse. Although you can manually edit build.xml files in each feature and plug-in, they are typically generated by the Eclipse pde-build plug-in. As a result you will need to download a fresh source build zip file when major changes occur to Eclipse source, such as the addition or removal of plug-ins. The version of Eclipse a particular source build will create is embedded in the source build zip file name. For example, eclipse-sourceBuild-I20030624.zip builds Eclipse from integration build 20030624.

Building Eclipse using Ant and a JDK</h2>

Description

<p>Produces an Eclipse SDK using the Java compiler you have installed.

System Requirements

1. <a href="http://ant.apache.org/">Ant 1.7.1</a> or higher
2. <A HREF="http://java.sun.com/javase/downloads/index.jsp">1.4, 1.5 and 1.6</A> JDKs
3. <a target="extra" href="http://www.info-zip.org/pub/infozip/">Info-Zip</a> zip and unzip executables on system path. Tar for *nix distributions
4. <a href="http://ccvs.cvshome.org/servlets/ProjectDownloadList">CVS 1.10 </a> or higher
5. 1 GB free disk space
6. Source build zip from <a href="http://www.eclipse.org/downloads">eclipse.org</a>

Initial Setup

Install Ant, 1.6 JDK, and a CVS client, as per each program's instructions. Minimally

you will need the following environment variables set.

1. Add the Ant bin directory, and the CVS executable to your path.
2. Set the JAVA_HOME environment variable to the root of your 1.6 JDK installation.
3. Set the ANT_HOME environment variable to the root of your Ant installation.
4. (Windows 98) Set the HOME environment variable to c:
5. (Windows 98) Increase the default environment space as specified <a href="http://support.microsoft.com/default.aspx?scid=kb;EN-US;q230205">here</a>.

Run the Build

1. Extract the eclipse-sourceBuild-*.zip to a directory. Extract using tar if using a *nix drop.
2. Update the build.properties file included at the root of this zip to point to the bootstrap classpath of your 1.4, 1.5, and 1.6 JDK locations.
3. cd to the buildScripts directory.
4. Execute build -os <osType> -ws <windowSystemType> -arch <architecture> [-bc <bootclasspath>] [-target <target>]

Parameter Name	Description
osType	Target operating system (<a href="#build_platforms">See supported types</a>).
windowSystemType	Target windowing system (<a href="#build_platforms">See supported types</a>).
architecture	Target system architecture (<a href="#build_platforms">See supported types</a>).
bootclasspath (optional)	The default list of bootclasspath jars to compile against using either a colon or semi-colon as separators. The jars that make up a bootclasspath are part of any JDK or JRE. Typically this parameter is only specified if you are cross compiling Eclipse. The default is set to the jars in the JDK or JRE in JAVA_HOME.	target (optional)	The Ant target from build.xml to execute. The default target is run and performs a complete fetch, build, javadoc build and install. Other valid targets are: fetch compile install

 

Install Eclipse

When the Eclipse build is complete, there will be a zip file called

<osType>-<windowSystemType>-<architecture>-sdk.zip

in the results subdirectory of your build directory. If you are building for Linux or Mac, there will be a tar.gz file.

</p>

Extract this file to the directory where you would like to run Eclipse. If you extract it to your root directory, a directory called eclipse will be created.

Supported Platforms

Eclipse can be built on any of the following platforms. With some <a href="#limitations">limitations</a> any platform can be used to build Eclipse for any or all supported platforms. To see the latest information on the platforms supported for a given release, refer to the latest <a href="http://www.eclipse.org/eclipse/development/">project plan</a>

Operating System (os)	Windowing System (ws)	Archecture
win32	win32	x86
win32	wpf	x86
linux	gtk	x86
linux	gtk	x86_64
linux	gtk	ppc
macosx	carbon	ppc
macosx	cocoa	x86

aix	motif	ppc
solaris	gtk	sparc
linux	gtk	s390
linux	gtk	s390x

Known Limitations

1. Building unix flavours of Eclipse on Windows will result in incorrect file permissions. The *.so, *.sl, and Eclipse executable files will not have execute permissions. In addition, linux-motif and linux-gtk builds will not have soft links to libXm.so.2.1 in the installation root directory. In these cases you would have to write an install or post install script to set permissions properly. (UNIX builds built on UNIX systems will set sufficient permissions and make the appropriate soft links).
2. Only Java source code is compiled. *.dll, *so, *sl and Eclipse executables are all checked out of dev.eclipse.org prebuilt in this build process. The instructions on <a href="http://www.eclipse.org/swt/faq.php#buildeclipseexe">recompiling

      the eclipse executable</a> and <a href="http://www.eclipse.org/swt/faq.php#howbuilddll">recompiling
      the swt libraries</a>  available in the <a href="http://www.eclipse.org/swt/faq.php">SWT

3. For the platforms where JDK 1.6 support is not yet available e.g linux-gtk-s390, linux-gtk-s390x the Eclipse SDK can be built with JDK 1.5 in place JDK 1.6. To do that, please follow the following steps:
   • Edit

     the file build.xml: replacing the tags <property name="javacSource" value="1.6"> with <property name="javacSource" value="1.5"> and <property name="javacTarget" value="1.6"> with <property

     name="javacTarget" value="1.5">
   • Remove code which compile

     and package the plugins that require JDK 1.6 currently: org.eclipse.jdt.compiler.tool, org.eclipse.jdt.compiler.apt and org.eclipse.jdt.apt.pluggable.core from the files features/org.eclipse.jdt/feature.xml and

     features/org.eclipse.jdt/feature.xml.
   <property name="javacSource" value="1.4">
