Just delete the folder where it's installed. I doubt re-installing it will fix any problems. It's not likely that it's not installed properly; it's more likely you need to configure something properly....

Thanks!
The problems I have been seeing seem to be down to:
- I had installed part of Eclipse on my SSD, with the data on my HDD which I had understood causing some issues
- I had installed various Android SDK packages and this has filled up all the space on my SSD I have tried to select uninstall the packages but that hasn't restored the space?
Any advice/help would be appreciated!
Thanks!

I see. By default the Eclipse Installer uses a shared bundle pool that is shared by all installations. By default this is in ~/.p2/pool, where ~ is your home folder. If you home folder is on a drive with limited space, you can delete this folder, keeping in mind that this will destroy all installations you've created (which you should then also delete). When you start the installer again, first use the menu in the upper right to invoke "Bundle Pools...". There's also a control on the menu to switch off the use of bundle pools, but then if you create multiple installations you'll download multiple copies of the same bundles, so you'll waste disk space and it will take longer to create each installation. Via the Bundle Pool Management dialog, you can create a New Agent... and choose (create) a folder location on a drive that has plenty of space. The pool will be created nested in agent folder and you can select that pool for use by the installer. The installer will use the pool you choose in this dialog and remember this choice in the future.

That's great!

Really appreciate the help!

Before that I need to (I think) clear out the ~50Gb worth when I installed Android SDK packages.

I think I have backed out the packages but where is the ~50Gb left from it?

Cheers!

It seems highly unlikely that installing Eclipse package used ~50Gb of space. I I have a pool that was used for more than 500 installed Eclipse IDEs (various packages with versions from Juno through Photon) and it's using less than 28Gb. In any case, I've told you where the pool is located in your home folder, i.e., .p2, so if you're deleted that, you've already deleted any large files associated with an Eclipse installation. I'm not sure if you're one Windows, but I've had problem there with the tmp folder filling up with crap that never seems to be cleaned out. You can look at the properties of a folder (on Windows) to see how much disk space it uses. You'll need to use some approach like that to find out where your space is being consumed.

Thanks again - I think its getting clearer!

Your correct, there isn't that much from Eclipse - a couple of Gigs tops.

My SSD is clogged up by Androud, with 55Gb in the system-images. Can I just zap that or something else?

I really appreciate all help. Cheers!

Sorry,I don't know anything about Android images. Did you create them yourself or did the Android package create them for you? Are they nested in some workspace you created? Are they nested under your ~/.eclipse folder?

Cheers.

Yes I created using the Android packages and I think it's generally OK now - thanks - but the Android SDK is "a work in process".
I have moved all the to my HD - which has at least allowed me to have sufficient to stop Windows complainish every five minutes :-).
I am trying to reinstall SDK - and will let you know if its all pulled together.

I've got a little "p'ed off" - ahh.
I followed all the advise but I think I got it a tad messed up...
So now, I think I cleared it down:
Help -> About Eclipse -> Installation Delails -> (select all) Uninstall all the Android
Then started again: I get a message "Android SDK: ...use SDK Manager to install" then I get an error "Failed to get the required ADT version...Toolkit may not work properly".
I try the SDK Manager which closes without any error or anything at all.
Any ideas please? Can I just restart again? Any ideas please?
Am I misunderstanding or can I now just delete Eclipse and then reinstall Eclipse and then Android?
Thanks you.

Sorry, I personally can't answer any questions about installing Android. I don't know what the Android SDK Manager is. Is it this this thing?

https://developer.android.com/studio/command-line/sdkmanager

Did you invoke "SDK Manager" from the IDE or is it a separate tool that you've downloaded from somewhere, perhaps from here:

https://developer.android.com/studio/#command-tools

I think the SDK is from here:
http://www.oracle.com/technetwork/java/javase/downloads/jdk8-downloads-2133151.html

Yes I use the SDK manager which was working but I seem to have broken it all. If I select the "Android SDK Manager" it just doesn't do anything - it just doesn't give an error; or when uninstall the SDK and reinstall it, it just days "Failed".
It's not very happy at all, and every direction I tern too just get's blocked.
Can I uninstall Eclipse and start again?
(Really appreciate your help especially that this isn't your areas.)

I'm a little confused. The link is for a Java SDK. That will, at least by default, install into C:\Program Files\Java\jdk* and has an annoying tendency to remove older Java installations without asking, which can break any installation or mess up any Eclipse workspace that was using the older one. As a "real" installer, it makes changes to the system and modifies the system registry. It's relatively dangerous to mess directly with any files that it creates without understanding which references in the system registry might be broken when you do that.

It seems that somehow you are saying that the Java SDK manager is also providing the service of being an "Android SDK Manager" but I don't get that at all. The https://projects.eclipse.org/projects/tools.andmore support was dropped from the release train in Oxygen so that's several years old. So I don't actually know what exactly you've installed to get your Android support and I don't know what you've done to download and Android SDK, if not the think described in https://developer.android.com/studio/command-line/sdkmanager so I'm in the dark of what you are running and how it manages Android SDKs. Perhaps a picture is worth a thousand words.

In any case, your issue of ire seems not directly related to the Eclipse Installer, but more a problem with tools you're getting from other providers; at this point I don't understand exactly which tools those are and where you got them from.

Sorry, I confused myself :-(

I installed the ADT using https://stuff.mit.edu/afs/sipb/project/android/docs/sdk/installing/installing-adt.html

At this point I get the response highlighted previously (i.e. selecting the Android SDK either doesn't do anything or says "Failed to get the required ADT...".

I have tried to reinstall Eclipse but I still get the same problem with the Android SDK.

Thanks again.

Sorry, but all the ADT support is something provided directly by Google. It's not an Eclipse project so I can't directly help with that. Further, currently Google chooses not to support ADT anymore. As a result, the Eclipse Andmore project https://projects.eclipse.org/projects/tools.andmore was started, but that seems no longer so active either: https://projects.eclipse.org/projects/tools.andmore/contact I've not seen an Android package for several years now. I suspect at this point your best to use what Google is currently supporting: https://developer.android.com/studio/
