Go >= 1.11
----------
For Go version 1.11 or later, you should clone the repo (without having
`$GOPATH` set) and `cd` into the directory:
$ unset GOPATH
$ git clone https://github.com/restic/restic
$ cd restic
Then use the `go` tool to build restic:
$ go build ./cmd/restic
$ ./restic version
restic 0.9.2-dev (compiled manually) compiled with go1.11 on linux/amd64
You can run all tests with the following command:
$ go test ./...
