为什么在运行测试时工具-deps再次下载所有依赖项

Question

你好，

我试图下载所有依赖项，这样CI上的测试和其他步骤就不需要下载了。

我使用以下命令下载所有依赖项
clojure -Sdeps '{:mvn/local-repo ".m2"}' -A:dev:test:prod:frontend -Spath > /dev/null
我可以确认`.m2`和`.cpcache`目录都存在。

但是当我运行
clojure -Sdeps '{:mvn/local-repo ".m2"}' -M:dev:test
所有依赖项都被再次下载。

这种情况在本地和CI上都能复现。

描述
{:version "1.10.3.967" :config-files ["/usr/local/Cellar/clojure/1.10.3.967/deps.edn" "/Users/kirill/.clojure/deps.edn" "deps.edn" ] :config-user "/Users/kirill/.clojure/deps.edn" :config-project "deps.edn" :install-dir "/usr/local/Cellar/clojure/1.10.3.967" :config-dir "/Users/kirill/.clojure" :cache-dir ".cpcache" :force false :repro false :main-aliases "" :repl-aliases ""}

```

首先期望执行命令以获取所有依赖项
```
clojure -Sdeps '{:mvn/local-repo ".m2"}' -A:dev:test:prod:frontend -Spath
```

当运行测试时，预计不会获取任何依赖项
```
clojure -Sdeps '{:mvn/local-repo ".m2"}' -M:dev:test --profile :ci
```
```

我还没有深入研究这个问题，但是通过指定不同的别名，你会得到不同的依赖集，所以它会下载新的依赖版本。

例如，第一个版本不使用honeysql，而第二个版本使用了honeysql，因此它必须下载。如果这两个计算之间有版本差异，那么第二个可能下载已经存在的库的新版本。

重新运行你列出的任意一个命令都不会下载新的库，问题在于这些命令不同的依赖集，所以你假定不应该发生下载的假设是不正确的。

啊，对了，`frontedn` 排除了很多依赖，有道理。
