Go Language (golang.org)
version 0.9.15.3 in my IntelliJ Idea.~/Desktop/go/sdk
however it wasn't able to recognise it. I got this error in Event Log:14:03:02 IllegalArgumentException: Argument for @NotNull parameter 'virtualFile' of com/intellij/openapi/projectRoots/impl/ProjectRootContainerImpl.addRoot must not be null
Any idea how IntelliJ Idea is able to recognize it would be appreciated. Thanks.
Please consider using one of the alpha releases for 0.9.16. I believe that alpha7 could be the more stable one rather than alpha9. You can get them from GitHub releases
The v1.0.0-alpha0 branch is, as the name implies, an alpha release and it's in the early stages of development, that's why there's no release done yet for it as well.
P.S. I'm one of the contributors to the plugin.
