go构建项目与打包

package main

// 初始化ADB环境

// 构建项目

    cmd.Dir = ProjectPath
    output, err := cmd.CombinedOutput() // 获取输出和错误信息

        logrus.Fatalf("build failed: %s", output)
    }

// 获取项目的绝对路径

    if err != nil {
        logrus.Fatalf("get project path failed: %v", err)
    }
    ProjectPath = dir
}
 
// 设置GOOS和GOARCH
func setGOOSAndGOARCH(targetOS, targetArch string) {
    if targetOS != "" {
        os.Setenv("GOOS", targetOS)

    var targetOS, targetArch string
    if len(parts) > 0 {
        targetOS = parts[0]
    }
    if len(parts) > 1 {
        targetArch = parts[1]
    }
    return targetOS, targetArch
}
 
// 根据目标平台构建项目
func buildForTarget(target string) {
    targetOS, targetArch := getTargetOSAndArch(target)
    setGOOSAndGOARCH(targetOS, targetArch)
    fmt.Printf("building for target: %s\n", target)
    buildProject()
}
 
// 主函数
func main() {
    initADBEnv()
    getProjectPath()
    fmt.Println("Initialization complete.")
    fmt.Println("Please enter the target platform for cross-compiling, for example: linux-amd64")
    var target string
    fmt.Scanln(&target)
    buildForTarget(target)
}

这段代码首先导入了必要的Go模块，并定义了全局变量。然后初始化了ADB环境，获取了项目的绝对路径，并提供了构建项目的方法。代码还包含了设置GOOS和GOARCH环境变量的功能，以支持不同操作系统和架构的
