ok, I'm a bit closer to the problem. it's related to eclipse.p2.data.area property in configuration/config.ini Initially, when product is first installed, eclipse.p2.data.area points to absolute path in product main install dir, e.g. "file\:/Applications/Abc/eclipse/p2" At this time, everything seems possible to update and remove, at least from p2 UI. After any provisioning operation, the eclipse.p2.data.area get's replaced with relative path "@config/../p2"
Now on next product run, a new p2 folder is created next to cascaded configuration area - somewhere in user directory. (Although this folder never existed before) >From now on, nothing seems possible to update or uninstall from p2 UI. Now if I create a symbolic link from cascaded/p2 to /Applcations/Abc/eclipse/p2 all is updateable again. So If I'm getting this correctly, p2 converts eclipse.p2.data.area absolute path to relative path with "@config" and then resolves "@config" variable to cascaded directory, instead of main directory. 2011/3/22 Jacek Pospychała <[email protected]> > hi, > > I'm trying to understand what is this property > "org.eclipse.equinox.p2.type.lock", who sets it and why. > > > Basically, there's a Mac product with extreemly confusing configuration.
