The eclipse product configuration has the section "launcherArgs" which can be specified globally or for any supported platform. We build our product for win32 as x86 and x86_64 and I want to have a different .ini generated depending on the arch property. To be specific: It´s an in-house application and the JVMs are rolled out to the same directory on every client, but differs between 32bit and 64bit machines.
We build with maven/tycho.
It can be achieved in the p2.inf advice file using these keywords:
filter=(&(osgi.os=win32)(osgi.arch=x86_64)) instructions.configure=setProgramProperty(propName:-vm,propValue:64bitVM)
It´s actually not that easy and the correct syntax of the p2.inf file remains a miracle to me. But somehow I got this working. A look to the content.xml file can be helpful if anyone also want´s to do stuff in the p2.inf file...
