Unfortunately I'm having the same issues, I assume this plugin in potentially using an older version of Java, is there a chance of potentially looking into this? thank you

Me too, similar issue encountered for IntelliJ IDEA 2017.2.5

INFO - llij.ide.plugins.PluginManager - Plugin 'Haskell' can't be loaded because: This plugin version was marked as incompatible

Would be great if there is a chance that this is fixed - and thanks for maintaining the plugin. :)
