[Solved]-Plugins won't install on Eclipse-eclipse

I think you need the maven plugin in order to install your plugin. If that's the case, you can follow this this instruction to install it.

Use eclipse update manager to install the plugins.. Then it will automatically select dependent plugins..You dont need to bother about dependent plugins in that case

All I had to do was completely open up full permissions for all users to the directory. This is dangerous if you have a multi-user system but Windows 7 seems to default to giving processes not very high permission levels; some processes (such as Eclipse Updated) don't know how to deal with this and request user permission, so they just bomb out. Easy fix: full control to all users and processes for the Eclipse Directory.

I had this problem, but I had to dig harder to fix it.

The source of my problem was the shortcut to launch Eclipse had this in the Target field:

"C:\Program Files\eclipse\eclipse.exe" -configuration C:\Program Files\eclipse\configuration

The problem with this is that without double quotes around the "-configuration C:\Program Files\eclipse\configuration" section it would hit that space in 'Program Files' and use C:\Program for storing configuration some of the time. Generally, if you have C:\Program you should make sure programs didn't put random files in there by mistake.

To fix this I had to move the configuration files from C:\Program to C:\Program Files\eclipse\configuration, picking and choosing along the way. Change the Target field to:

"C:\Program Files\eclipse\eclipse.exe" "-configuration C:\Program Files\eclipse\configuration"

and I was good to go.

I had the same problem, and I solved it by setting

"Contact all update sites during install to find required software"

to true.

(I used the Eclipse install manager, in Eclipse IDE for Java Developers, Version: Indigo Service Release 1 )

In my case, updating to the latest version of Eclipse (Juno) did the trick. Perhaps your add-on won't run on your version?

Hi I had the same problem just yesterday. I was uploading SDK for android and found your question in a google search.

I reverted back to an older version of eclipse. Link to older version of eclipse

This solved it for me.

Remember to delete eclips from your program files. You do this by just physically deleting the file from program files (not through uninstall). Then also make sure you delete your workbench. This is a file called workbench in your docs. Well mine was in my docs, it could be somewhere else on your system.

I am using windows 7.

Best of luck.

There's an alternative to running Eclipse as an administrator: you can manually give write permissions to your "eclipse" folder for all users (or just your current user). This way Windows/UAC won't pop up the security question that you see when you run programs as admin.
