[equinox-dev] [prov] p2 provisioned eclipse missing companion library

[Timothy Webb <tim@xxxxxxxxxx>]

Are others having success using p2 to provision an Eclipse where the  
cache directory is not collocated with the eclipse exe?

I'm running into an issue where despite having what appears to be the  
right set of software downloaded in the cache, configured in the  
platform.xml / config.ini, etc., each time I try to run the  
eclipse.exe, I receive "The eclipse executable launcher was unable to  
locate its companion launcher jar."  In looking through the C code for  
the launcher, it looks like Eclipse is designed to search for the  
companion library in the plugins area, located near the exe, or by  
specifying --launcher.library on the command line.  In our eclipse.ini  
file we drop down next to the exe, I don't see a --launcher.library  
argument configured.  Is this something that should be setup by  
default in the normal touchpoints?  Or, is there a branch of the  
Eclipse.exe that is designed to work better with p2-style deployments?

Thanks,
Tim
