This post is about building the whole Eclipse IDE from the source code - and more in particular how to specify the target OS you want to build the executable for.
I found the following tutorial to guide me through the build procedure: http://www.vogella.com/tutorials/EclipsePlatformDevelopment/article.html
Especially chapter 13 of that Tutorial is helpful. I will describe the steps that need to be taken one by one here - so you don't need to read the vogella tutorial.
NEEDED SOFTWARE :
Apparently you need to have the following software installed on your (Windows) machine:
- Git
- Maven Version 3.3.1 (make sure that the bin folder where you extract Maven is added to the PATH. For installation instructions see https://maven.apache.org/install.html)
- Oracle 1.8 JDK or higher (don't forget to set the JAVA_HOME environment variable)
Now you're ready to start:
STEP 1 :
Create a new folder in the C: disk. Let's name it C:myEclipse. This will be the folder in which we pull the Git repository of the latest Eclipse version.
STEP 2 :
Open the Windows cmd shell with administrator privileges (right click on cmd icon if you made one on your desktop, and select open with admin rights). Go to that folder through the command cd C:myEclipse. Now type the following command: git config --system core.longpaths true. This notifies Git that long names can occur in the repository. Forget this command and it will result in errors later on.
STEP 3 :
Clone the Git repository:
git clone -b master --recursive git://git.eclipse.org/gitroot/platform/eclipse.platform.releng.aggregator.git
Now you should have some patience for all the sourcecode to get copied to your local folder.
STEP 4 :
Finally it is time to start the build. The build procedure will already take hours, so it is wise to skip the unit tests. Therefore do not forget to add the -DskipTests parameter. This is the command to start the build:
mvn clean verify -DskipTests
After some hours, the build should be finished.
STEP 5 :
The results of the build should now be in the following folder:
C:myEclipseeclipse.platform.releng.aggregatoreclipse.platform.releng.tychoeclipsebuildersdktargetproducts
Notice that the Eclipse IDE is built for all possible target machines. 32-bit Windows, 64-bit Windows, Macintosh, Linux, ... No wonder it takes hours! I would like to build for just one single target - for example my 64-bit Windows machine. This will hopefully reduce the build time significantly and allow me to verify code changes quicker.
Does anyone know how to achieve this?
EDIT :
I have added the argument -Dnative=win32.win32.x86_64 to the build command. Unfortunately, I get an error after 15 to 20 mins. This time, I've added the argument -X as well, to get debug information:

I still have no answer, so I started a bounty. Please reproduce step 1 until step 5 on your machine (with the -Dnative=win32.win32.x86_64 argument added to the fourth step). Do you achieve a successful build of the Eclipse IDE for just one OS target (preferably Windows 64-bit)? Does the build go faster - compared to the general build process that targets all OS's?
PS: I've got some other questions related to the Eclipse "Build from scratch" topic. If you're interested:
- Building Eclipse IDE from scratch - how to choose CDT over JDT?
- Building Eclipse IDE from scratch - how to specify the target OS?
- Building Eclipse IDE from scratch - making bigger icons sometimes successful
Let us all unite to build the Eclipse IDE ourselves - and tweak it to our needs ;-)
EDIT :
Mr/Mss. Zapl wrote an interesting comment. He/She thinks that the -Dnative argument is not correct, after he/she read the following link:
http://comments.gmane.org/gmane.comp.ide.eclipse.cbi.devel/896
Hopefully we'll get closer to the answer now :-)
