What does it have to do with C++? – Touchwood

The GOPATH seems to be incorrectly configured as well as the project seems to be in the wrong place. The project GOPATH should be removed and the project should be created under /home/batis/gocode/src/your/project/path. Then, make sure you have the dependency under /home/batis/gocode/src/github.com/therecipe/qt – Valenti

@Valenti Moved the project to /home/batis/gocode/src/batis/Qt. Problem still exists. Tell me please how you can check the dependencies. – Gamete

project GOPATH deleted. – Gamete

Answer 1

The methods are defined in a big generated file that is not indexed by Gogland. To change the limit you should change idea.max.intellisense.filesize.

To do this, open custom properties file via Help | Edit Custom Properties menu and add something like this: idea.max.intellisense.filesize=4500 for 4.5 MB limit. The size is in Kilobytes.

Please use carefully, indexing large files may influence index update speed dramatically.

Answer 2

Ran into this recently with a project in 'bitbucket.org' GOPATH not finding ones in 'github.com'. Checked the "Index entire GOPATH" box and it fixed it.

This option is present at: Files > Settings (Preferences) > Go > GOPATH

This sorted me out after updating to 2020.1. – Upgrowth

The option is present at : Files > Settings (Preferences) > Go > GOPATH – Ofris

This eventually worked for me though I had to restart Goland – Carey

Answer 3

Possibly not valid for the original context, but the workaround I discovered is to rename the file where the method or other identifier is defined, allow Goland to reindex, and then rename it back to the original name.

what if this happens for 100 files? – Celebes

This was the only thing that worked for me after trying the other avenues. Restarting didn't even work. – Steapsin

I tried this, I renamed the file (first it asked me to confirm because the file was from outside the project), and it worked. Then I tried to rename it back to the original and the IDE wouldn't let me (wouldn't even show the confirmation prompt). But then the "undo" worked, even though it didn't show that it worked until I restarted. Very confusing, but thanks for the suggestion! – Squarrose

Answer 4

For me, none of the above solutions worked. Finally I could solve it by enabling "Enable Go Modules Integration" checkbox located under Preferences > Go > Go Modules.

Answer 5

I had the same problem and this worked for me:

1. From the main menu, select File | Invalidate Caches.

2. In the Invalidate Caches dialogue, you can select additional actions that the IDE will perform while removing the cache files:

3. Clear file system cache and Local History

4. Click Invalidate and Restart.

This can also happen if go.mod is copied from another project without updating the project name:

// go.mod

module github.com/org/new-project

go 1.15

Answer 7

For me, it was that I had GOPATH set to 1.15 but GOROOT set to 1.14, so you need to set them to the same version. You can find these settings in Preferences -> Go -> GOROOT or GOPATH.

I use gvm - Go Version Manager, that's why I have multiple Go versions in my system.

Answer 8

I had the same issue with Goland 2021.1 on Windows 10 with go SDK 1.13. I solved the problem by installing the latest go version 1.16.3 side by side to version 1.13 that I need for my projects. It turned out that my Windows 10 OS was patched with security updates that are not compliant with GoLand 2021.1 and SDK 1.13

Answer 9

You need to "Enable Go Modules Integration" by going into "File" and selecting settings and then "Go Modules"
