我正在尝试使用 OpenCV https://opencv.org/通过 Origami使用lein-lambda部署。然而，我的 target/ 目录最终为 350Mb，而 lambda 要求未压缩上传的最大值为 250Mb。
如果我查看target/的内容
$ tree -L 2 target/
target/

└── stale
└── leiningen.core.classpath.extract-native-dependencies
我注意到还有针对 macosx 和 windows 的 OpenCV 版本。如果我可以在 lein lambda 部署生产命令期间删除这些构建，那么它应该足够小。
这是我的project.clj 文件，也许它与uberjar有关:

最佳答案
只需使用 jar 排除:
:jar-exclusions [#"^docs/.*" #"^public/js/.*" #"^example-data/.*"]
关于java - Clojure AWS Lambda 函数中的 OpenCV 目标大于 250MB，如何减小其大小？，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/49212002/
