当我在同一个项目（具有不同的参数）中运行两个或多个 clojure 实例时，它们最终会竞争相同的缓存文件夹，该文件夹被创建在同一路径中。在这种情况下，我们看到的错误是 无法找到或加载主类 clojure.main。有时还有其他错误。
如果正确理解脚本逻辑，它会选择当前目录作为缓存并使用参数组合的哈希作为唯一标识符，但在我的情况下最终生成的文件夹是相同的。
# Determine whether to use user or project cache
if [[ -f deps.edn ]]; then
cache_dir=.cpcache
else
cache_dir="$user_cache_dir"
fi
将非常乐意引入锁定机制以防止竞争情况，或者作为处理程序提供一个指定缓存目录额外参数或校验和的选项。
