我有一个可能和Java互操作与反射有关的问题。研究这个问题让我查看了Clojure FAQ关于非法访问。它提到添加--illegal-access=debug
。半小时后,我仍然无法解决这个问题。这真是个奇怪的问题,但是我在尝试运行添加参数的考验时确实有些困惑。我看了clj --help
和依赖和CLI指南,但这需要太大力气,我觉得肯定遗漏了某个指南或文档页面。
% clj -e "\*clojure-version\*"
{:major 1, :minor 10, :incremental 0, :qualifier nil}
% clj --illegal-access=debug

我还有一个运行在Docker镜像中的clojure(FROM clojure:openjdk-18-tools-deps-1.10.3.1040-bullseye
)也不能用
