在Gitlab CI中使用gomodules测试Go项目失败；包不在GOROOT中“；

我正在尝试使用下面的.Gitlab-CI.yml在Gitlab CI上构建和测试Go项目：

image: golang:latest

stages:
  - prepare
  - test
  - build
  - package

format:
  stage: prepare
  script:
    - make gofmt    

test:
  stage: test
  script:
    - make test

test race condition:
  stage: test
  script:
    - make race

coverage-html:
  stage: test
  script:
    - make cov

build win binary:
  stage: build
  script:    
    - make win

build linux binary:
  stage: build
  script:    
    - make linux
    
build mac binary:
  stage: build
  script:    
    - make mac

下面是管道中使用的Makefile：

# Go parameters
GOCMD=go
GOBUILD=$(GOCMD) build
GOCLEAN=$(GOCMD) clean
GOTOOL=$(GOCMD) tool
GOTEST=$(GOCMD) test
GOTESTRACE=$(GOTEST) -race
GOGET=$(GOCMD) get
GOFMT=$(GOCMD)fmt

BINARY_NAME=app
BINARY_DARWIN=$(BINARY_NAME)_darwin
BINARY_LINUX=$(BINARY_NAME)_linux
BINARY_WIN=$(BINARY_NAME)_win
    
all: build linux win

build: ## Download dependecies and Build the default binary      
        $(GOBUILD) -o $(BINARY_NAME) -v $(CURDIR)/cmd/app

linux: ## Build linux binary
        CGO_ENABLED=0 GOOS=linux GOARCH=amd64 $(GOBUILD) cmd/app -o $(BINARY_LINUX) -v $(CURDIR)/cmd/app

win: ## Build windows binary
        CGO_ENABLED=0 GOOS=windows GOARCH=amd64 $(GOBUILD) -o $(BINARY_WIN).exe -v  $(CURDIR)/cmd/app

mac: ## Build macOs binary
        CGO_ENABLED=0 GOOS=darwin GOARCH=amd64 $(GOBUILD) -o $(BINARY_DARWIN) -v    $(CURDIR)/cmd/app

test: ## Run tests for the project
        $(GOTEST) -count=1 -coverprofile=cover.out -short -cover -failfast ./... -v

race: ## Run tests for the project (while detecting race conditions)
        $(GOTESTRACE) -coverprofile=cover.out -short -cover -failfast ./...

cov: test ## Run tests with HTML for the project
        $(GOTOOL) cover -html=cover.out

gofmt: ## gofmt code formating
    @echo Running go formating with the following command:
    $(GOFMT) -e -s -w .

我正在使用

gomodule

管理依赖项。我很难理解的是，如果我先在

build

阶段运行作业，管道就能够下载依赖项并成功地构建二进制文件。但是当运行

测试

阶段中的作业时，它们都会失败，并出现以下错误：

main.go:3:8: package app/command is not in GOROOT (/usr/local/go/src/app/command)
make: *** [Makefile:31: test] Error 1
Cleaning up file based variables
ERROR: Job failed: command terminated with exit code 1

---

在我需要配置的Gitlab CI上测试基于

gomodule

的项目时，是否有其他设置？

您是否设法解决了这个问题？原因是什么？你解决问题了吗？原因是什么？
