Why cannot find declaration to go to in IntelliJ Idea?

Question

I have a code in go, and I am using IntelliJIdea for development. It used to work fine, but since the time I have changed the folder where the code used to be, IntelliJ has been behaving in a weird manner. It shows me a lot of unable to find declaration to go to errors. After changing the folder where my project used to be, I changed the GOPATH and imported from the new directory once again.

I am attaching the screenshot as that will be better for understanding.

See the conductor.Start(). This function is right there in the package app. But it can't find this.

PS: I have tried importing the project from scratch and invalidating and restarting multiple times, but that didn't help.

@eduncan911, the GOPATH that is set on my system is: `/Users//Desktop/Work/Cloud/godir`. And my project is at, `/Users/Desktop/Work/Cloud/godir/src/stash/cloud/conduc`. — John Dui, Oct 10 '16 at 03:10

I'm using Gogland, which is also a JetBrains IDE, but I also had a problem with symbols not getting resolved.

I fixed it by deleting the project's index file.

Close the IDE.
In your project directory, find a directory named ".idea".
Delete all files with the extension ".iml" in that directory.
Restart the IDE.

The project should get reindexed and symbols will be resolved.

this worked. However, I had to perform one additional step after 4, to manually add back .iml file, as it was not created automatically. – user7630232 Dec 09 '20 at 07:10
I also had to manually put back the .iml file but it still didn't work for me. – molundb Nov 14 '22 at 09:28

For my case, Intellij didn't have Rust installed. I found that out while trying to create a new project (it had JAVA and other language support). As soon as I installed Rust, it worked.

For my case, I have 2 virtual environments, and I found that I did not set the correct environment in Pycharm. The environment I used did not include these packages. After I changed the environment, everything goes well.
