Eclipse “Duplicate Location” while install new Sequoyah plugin?

Question

When I am trying to install Sequoyah in Eclipse from Help -> Install New Software , either through online installation or using downloaded local site archive it gives error Duplicate Location.

Or even first time when I select the downloaded archived file it does not show the files rather check box with There are no categorized items

please help. I even tried to delete Eclipse and unpack and did all this again but same problem.

Answer 1

It didn't show up for me in "Preferences->Install/Update->Available Software Sites", but I was able to get it work. I could add it from there and I didn't get the error message. Then, I had to click "Disable", "Reload", "Enable", "Reload", or else it would disappear after closing the window. I'm not sure if all those clicks were strictly necessary, but it worked!

Answer 2

I run into this fairly often when installing new versions of eclipse and not being able to use update sites that I added in the old version.

Try this:

• Preferences->Install/Update->Available Software Sites (or control-3 and type "sites")
• look at the list of disabled sites (filter text is helpful to search them) and see if the one you want to use is listed as disabled
  • enabling it will make it show up in the Install New Software drop down
