I have a set of favorite Eclipse plugins, that I need to install every time I install new Eclipse. I would also like to have a way to install all those plugins in [semi-]aut
As said by Bananeweizen at 2013-3-20
Use (File -> Export -> Install -> Software Items to file) to prepare plugin list file (*.p2f), then
(File -> Import -> Install Software Items from File)
I have assembled Eclipse Node.js IDE this way, see Enide - Eclipse Node.JS IDE

UPDATE: This however ran into bug in Eclipse Kepler
WARNING: Not so good in Kepler: There are 2 bug in Eclipse 4.3 Kepler, that may make "File -> Import \ Install" usage not comfortable.
Please help to get Kepler bugs fixed by voting on these 2 bugs (you should be registered on dev.eclipse.org and logged in).
