"Plugin Scala is incompatible with this installation" error with IntelliJ 14

Question

From Browse Repositories in IntelliJ 14, the newest Scala plugin is version 1.5.2.

From the Scala plugin homepage for IntelliJ, the latest version (as of Aug 10, 2015) is 1.7.4. https://plugins.jetbrains.com/plugin/?id=1347

However, when I tried to install it from "Intall plugin from disk ..." after downloading scala-intellij-bin-1.7.4, I got this error:

What might be wrong?

Answer 1

On the link that you've provided you can see that compatible Intellij Idea builds for 1.7.4 version are 142.3553 — 143. The latest 14 Idea build has version lower than 142 - so it's incompatible with this plugin version. There is already EAP Intellij Idea 15 which you can download and install new scala plugin version on it.

Answer 2

I faced the same issue with 2020.2.4 Intellij IDEA. I just uninstalled the plugin and installed it again. Fixed the problem.

Answer 3

Try this way:

1. Go in settings - ctrl + shift + s
2. Plugins
3. Updates at the top
4. Push the button Update all Done!
