Hello guys,

I have an eclipse RCP app which supports both windows and macos x.

I would like to know if it is possible to use the same p2 repository for updating both windows and mac versions?

When i look inside the repo, the content of repository/binary seems to contain the executable, so i tried to put both windows and macos binaries into this directory but only one is working.

In content.jar, there is env specifc configuration, so i wonder if there is any mean to make several versions share the same repo, or if i need one repo per env?

Yes, it is possible to support multiple environments in the same p2 repository.
This is what the Eclipse Platform and the Release train repos are doing.
This is achieved by having IUs (one unit of xml in the content.xml file contained in the content.jar) have filtered requirements. For example you would have your main IU for your product (or some subpart) requiring the windows executable and also requiring the macos executable.

For this to work, you just need to export the application targeting multiple platforms.

Thank you Pascal for your quick reply.

Where should i do this?

I added an extra mac environment in my maven target-platform-configuration but when ran on windows, it failed buinding the mac version with this message:

Quote:

Cannot complete the install because one or more required items could not be found.
Software being installed: fast 2.0.3 (dp.fast.product 2.0.3)
Missing requirement for filter properties ~= $0: dp.fast.product.executable.cocoa.macosx.cocoa 2.0.3 requires 'org.eclipse.equinox.launcher.cocoa.macosx 0.0.0' but it could not be found
Cannot satisfy dependency:
From: fast 2.0.3 (dp.fast.product 2.0.3)

Cannot satisfy dependency:

To: dp.fast.product.executable.cocoa.macosx.cocoa [2.0.3]

I think it is the only place where i set something related to envirenment.

I also tried to uncheck "This product includes native launcher artifacts" in the product definition, and although it succeded building both products, in the repository i no more have the binary directory.

You need to specify the different target platforms that you want to support. See the following page for an example:
