when i am try to update from this site http://mantis.faratasystems.com/downloads/update/site.xml
i am running eclipse 3.4.1 and flex builder as a plugin how can i correct this error and install this plugin (Fx2Ant)
For me, the new plugin installer ‘p2’ gets often into an inconsistent state. My solution is to have three Eclipse installs: A work installation, a template and one ‘install’. When I need to install some plugin, I delete the ‘install’, copy it fresh from ‘template’ and then do the install in there.
After the install, I copy the new files under ‘plugins’ and ‘features’ to my work installation into the directory
eclipse/dropins/+ name of the plugin. See my blog for details.
