In windows, I deleted .p2 forlder due to some personal reason. Since luncher for eclipse was present in .p2 folder as below directory:
So eclipse is not getting started.
Please can any body suggests how to recover the .p2 folder in windows 10 without re-install the eclipse.
Eclipse version – Neon
Unfortunately this is not possible. By deleting the .p2 folder, you deleted almost everything except a few configuration and other small files. The folder .p2/poll contains not only the launcher plug-in but also all other plug-ins, the binaries of all Eclipse applications that have been installed via the Eclipse Installer.
