One week ago Go 1.14 was released with vendoring mode enabled automatically if the module root contains a vendor directory. Read this release notes by the Go team to learn about this change in detail. We’ve already supported this change in GoLand 2020.1 EAP, and even implemented similar behavior for Go versions 1.13 and lower. The IDE will automatically resolve imports to the vendor/ folder if it is present in the module.
In Preferences/Settings | Go | Go Modules, we’ve changed the Vendoring mode checkbox to read Enable vendoring support automatically. This setting cannot be disabled by language rules for Go 1.14, but for versions 1.13 and lower, we provide the option to disable it.
