当我在同一项目中运行两个或更多个clojure实例（参数不同）时，它们最终会竞争同一目录中创建的同一缓存文件夹。在这种情况下，我们看到的错误是“找不到或加载主类clojure.main”。有时还有其他错误。
如果正确理解了脚本的逻辑，它会选择当前目录作为缓存，并使用参数的组合哈希作为唯一标识符，但在我这个情况下，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
很希望要么引入一种锁定机制以防止竞争情况，要么作为解决方案提供一种指定额外缓存目录参数或使用的校验和的选项。
