[news.eclipse.technology.equinox] Re: Using the same Eclipse application

[Mickael Istria <mickael.istria@xxxxxxxxxxxxxx>]

Hi all,

I could find how to get it working without error on several platforms (win32 & linux).
When starting the application (in this case antRunner), Equinox loads all plugins that are listed in the osgi.bundles property of config.ini. This property is actually set when starting by reading the configuration/org.eclipse.equinox.simpleconfigurator/bundles.info file. However, even with DeltaPack installed in plugins/ or in dropins/, the bundles for other platforms are not added to this list, so that we cannot get the same eclipse working on several platform.
The workaround is, once DeltaPack is installed, to manually add the desired target bundles to the bundles.info.

This is what I added to my bundles.info to get it working on Windows:
# Win32 x86 bundles
org.eclipse.core.filesystem.win32.x86,1.1.0.v20080604-1400,plugins/org.eclipse.core.filesystem.windows.x86_1.1.0.v20080604-1400.jar,4,false
org.eclipse.core.net.win32.x86,1.0.0.I20080909,plugins/org.eclipse.core.net.win32.x86_1.0.0.I20080909.jar,4,false
org.eclipse.equinox.launcher.win32.win32.x86,1.0.200.v20090519,plugins/org.eclipse.equinox.launcher.win32.x86_1.0.200.v200905&ç/,4,false
org.eclipse.swt.win32.win32.x86,3.5.0.v3550b,plugins/org.eclipse.swt.win32.win32.x86_3.5.0.v3550b.jar,4,false
org.eclipse.update.core.win32,3.2.100.v20080107,plugins/org.eclipse.update.core.win32_3.2.100.v20080107.jar,4,false
# TODO add here macosx and other build platforms bundles

Wouldn't it be better to find a way to install the DeltaPack that would also add its included bundles into the bundles.info ? Then installing DeltaPack would make the Eclipse platform really multi-platform, and then builds could be run on any platform with the same Eclipse base?

Mickael
