EclipseFP 2.6.2 released!

I've just released EclipseFP 2.6.2. This is mainly a bug fixing release with a better handling of cabal sandboxes and related functionality. It wraps also an important change in scion-browser, which should now mean that Hoogle uses all the packages present in your sandbox, so should give better results.

Browse the release notes!

Install by pointing your eclipse to

This release is brought to you by me, myself and I. I would love to see more people contribute, even if only to install the development versions to provide some testing before the release, or write some documentation. There's work that can be done on the Haskell side, on the Java side, etc. Contact me if you're not sure, or send me pull requests! The code is at and

Happy Haskell Hacking!!

I did try 2.6.2 but :


Main errors I got:

You don't need SourceGraph for all the rest to work, so don't worry if it doesn't install. I actually didn't want to include it in 2.6.2 but a bug makes it so that we try to install it, but just ignore that.

I went on but now I have (last lines, after a lot of downloads) :

cabal.exe: The following packages are likely to be broken by the reinstalls:
Use --force-reinstalls if you want to install anyway.

What does that mean?

JP Moresmau said...

This means cabal was asked to reinstall a package on which all of these other packages depend. Check in your Haskell preferences if you have a path to buildwrapper and scion-browser, in which case you're good to go and just ignore that message.

I tried anew but I'm getting the same message and after that I get a "Not responding" EclipseFP. I think it's better to wait for a better released... Too bad for me, I used Eclipse-Scala without problem.
