My IDE just updated and now I'm getting this error :

I'm kinda new to IntelliJ and wanted to try this as well. Found this issue and a list of old releases at http://confluence.jetbrains.com/display/IntelliJIDEA/Previous+IntelliJ+IDEA+Releases

Tried with the community versions.

15.0.6 was completely broken, the one that goes also by 143.2370.31, and the next one 2016.1.4 aka 145.2070.6 complained:

[  17339]  ERROR - llij.ide.plugins.PluginManager - com.fasterxml.jackson.databind.exc.UnrecognizedPropertyException: Unrecognized field "prefix" (class com.neovim.ApiInfo$Id), not marked as ignorable (one known property: "id"])

Tested with the latest trial version as well, and it still dies :(

Any clues as to why?

Thanks!

I am also experiencing the same issue as @mjtorn , on intellij 2016.1.4. Judging from when this project was started and release dates of intellij, it looks like 2016.1.1 might work, but I can't find a download link.

Hi, thanks for the input for this bug. Sadly, I don't have personal interest to spend my free time on this project anymore for time being.

Either way, the bug might come from neovim (ApiInfo). The library this project uses to talk to neovim is somewhat immature, in sense that it's development had been stalled even before I started this project. I suggest that you try some older version of neovim, that might fix the problem or not. Even if it does, its not really a fix, just a work around.
