[`go mod vendor`](#go-mod-vendor) since modules were introduced. In lower
versions, `all` also includes tests of packages imported by packages in
the main module, tests of those packages, and so on.
-* At `go 1.17` or higher, the `go.mod` file includes an explicit [`require`

- transitively imported by a package or test in the main module. (At `go 1.16`
- and lower, an [indirect dependency](#glos-direct-dependency) is included only

- select a different version.) This extra information enables [lazy

+ * Because there may be many more `// indirect` dependencies than in previous
+ `go` versions, indirect dependencies are recorded in a separate block
+ within the `go.mod` file.
+ * `go mod vendor` omits `go.mod` and `go.sum` files for vendored
+ dependencies. (That allows invocations of the `go` command within
+ subdirectories of `vendor` to identify the correct main module.)
+ * `go mod vendor` records the `go` version from each dependency's `go.mod`
+ file in `vendor/modules.txt`.
A `go.mod` file may contain at most one `go` directive. Most commands will add a
`go` directive with the current Go version if one is not present.
