Intellij won't sync dependencies in Go project

Please make sure Go modules integration is enabled via Preferences | Go | Go Modules. After that, Sync Dependencies action should be available in go.mod file.

That was the problem.

I believe there was a ticket to fix this.  When there is a go.mod file in a project module integration is enabled by default.

You're right, Go modules integration should be enabled by default. However, there are several issues with that. Did you rollback between GoLand versions? 

I ran into this problem even with modules enabled.  For me the fix involved running the same go list command idea tried to see dependencies that needed a replace directive in the mod file.  Hope this helps if anyone runs into my version of the problem.

I also ran into similar issue, solution was close IJ then `rm -rf .idea/` and then re-open project.

Windows and wsl2 issue:

I also ran into this (even with modules enabled). Turns out, I was loading a project with `.idea` files that were transferred from macos and linux, and trying to open it in wsl2. I found that, instead of opening the directory like usual (`idea .`), I needed to create a new project from existing sources. Then Idea can properly set the wsl2 directory vars and env and so forth to make it work.  Hope that helps someone else.

I'm running into this problem because an `//indirect` references a tag that no longer exists, is there a way around this that doesn't require upgrading the chain of dependencies?

Daniel Valdivia Perhaps you can use replace directive pointing to a valid version in such a case? For instance, in go.mod file you can add something similar to 

replace github.com/example/dependency v1.2.3-beta.1 => github.com/example/dependency v1.2.2

Hard to say if this can work for 100% without testing with real-life project, but perhaps you can give it a try and see if this helps…
