Hi,

I doubt there is anyone on this mailing
list knowledgeable enough about p2 to help you with your problem.  You
could try p2's office hours on IRC (http://lenettoyeur-on-eclipse.blogspot.com/2011/09/p2-and-equinox-office-hours.html)

Hi,

I am building a rcp product with p2, but got an error when calling p2 director:

[java] [p2.director] Only one of the following can be installed at once:
[java] [p2.director] Cannot satisfy dependency:
[java] [p2.director] Cannot satisfy dependency:

[3.5.0.v20110530-7P7NFUFFLWUl76mart]

I looked at the generated p2.inf and found:

units.11.requires.2.name=bundle
units.11.requires.2.range=[1.0.0,2.0.0)
units.11.requires.2.greedy=false
requires.12.namespace=org.eclipse.equinox.p2.iu
requires.12.name=myproduct.product_root.win32.win32.x86

units.13.touchpoint.id=org.eclipse.equinox.p2.osgi
units.13.touchpoint.version=1.0.0
units.13.instructions.unconfigure=setLauncherName()

I think the requires.12 and requires.13 are conflicts but don't know how
to avoid it.

I didn't specify version in .product file. If I did that, I would get another
error:

[java] [p2.director] Installation failed.

dependency.
