In windows, I deleted .p2 forlder due to some personal reason. Since luncher for eclipse was present in .p2 folder as below directory: –launcher.library C:UsersXXXX.p2poolpluginsorg.eclipse.equinox.launcher.win32.win32.x86_64_1.1.401.v20161122-1740 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 .p2poll 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.
