Using Eclipse IDE on multiple devices-CodePudding

For starters, I use multiple computers, and sometimes, I use certain computers for once, and never again. This is something that I cannot fix. In such a case, I cannot go on downloading Eclipse IDE for work on every computer and then just leave it.

I tried installing Eclipse on a pendrive, and then using it for multiple computers, but it didn't work. As usual, eclipse.ini was the culprit. It contained paths from the computer I first downloaded Eclipse from, and that was the cause it didnt work in other computers. This error message showed up in other computers: The eclipse executable launcher was unable to locate its companion shared library.

Is there any way I can make eclipse entirely local to an external hard drive or pendrive for use on multiple PCs???

This is my eclipse.ini file:

startup
plugins/org.eclipse.equinox.launcher_1.6.300.v20210813-1054.jar
--launcher.library
C:/Users/pedne/.p2/pool/plugins/org.eclipse.equinox.launcher.win32.win32.x86_64_1.2.300.v20210828-0802

--add-opens=java.base/java.lang=ALL-UNNAMED

The only local references are in the C:\ drive at lines 4,8, and 13. Manually changing the paths for every computer isnt possible as I maybe using eclipse for the first time on multiple computers.

Any help, links to other answers, or moderation will be appreciated. Thanks!!!

CodePudding user response：

The .p2 directory is the location used by the Oomph installer style of Eclipse install.

Using the package style install from https://www.eclipse.org/downloads/packages/ will put everything in the Eclipse directory.

Note that this is still specific to a particular operating system. You can't have a single install for all operating systems.
