我有以下Gradle Exec任务，使用经典的个人访问令牌（启用所有repo范围）从GitHub下载文件：

tasks.register<Exec>("downloadScript") {

    val cmdLine = mutableListOf<String>("curl", "-H", "'Authorization: Bearer ${gh_token}'", "-H", "'Accept: application/vnd.github.raw'", "--remote-name", "-L", "https://api.github.com/repos/my_org/my_repo/contents/scripts/script.py")

    commandLine(cmdLine)
}

当我运行这个任务时，我得到了这样的输出：

> Task :downloadScript FAILED
  % Total    % Received % Xferd  Average Speed   Time    Time     Time  Current
                                 Dload  Upload   Total   Spent    Left  Speed

curl: (22) The requested URL returned error: 404

FAILURE: Build failed with an exception.

* What went wrong:
Execution failed for task ':downloadScript'.
> Process 'command 'curl'' finished with non-zero exit value 22

这里最有趣的部分是，在终端（IntelliJ本身或MacOS终端）中运行相同的命令通过，文件被下载，同时将${gh_token}替换为真实的的令牌。curl -H 'Authorization: Bearer token_string' -H 'Accept: application/vnd.github.raw' --remote-name -L https://api.github.com/repos/my_org/my_repo/contents/scripts/script.py
为什么使用变量将字符串传递给commandline（）会导致命令行插值失败，导致它失败？
