[pde-build-dev] Cross reference to muliple version plugin

["Chengdong Li" <chengdong.li@xxxxxxxxx>]

Hi,
As described in the followed figure, we have a product depends on on 2 
pre-built features FA which depend on plugin PA_2, and FB which depends on 
PB_1. In the baselocation, there are 2 different version of PA: PA_1 and 

PA_2, PA_2 is a higher version. Plugin PA is an independent plugin, it is not 
included in any features, for example, the org.eclipse.osgi plugin.

Product:
 |- FA
 |  |_ PA_2
 |
 |- FB
 |  |_ PB_1

BaseLocation:
 |- features
 |  |- FA
 |  |_ FB
 |
 |- plugins
 |  |- PA_1
 |  |- PA_2
 |  |- PB_1
.....

Question:
 - when using PDE product build, which version of PA will be discovered? 

Based on our build, on some machine PA_1 is chosen, and on others PA_2 is 
choosen.  Can someone explain how PDE product build discovers the plugin 
version in above case?


Thanks
