我正在设置compojure应用程序，并且希望使用datomic作为数据库-但是，一旦添加client-pro依赖项，我的应用程序将无法运行。
这就是我所做的：
datomic-pro transactor.properties并用我在电子邮件中收到的license-key对其进行了更新bin/transactor transactor.properties (require ‘[datomic.api :as d])
(def db-uri “datomic:dev://localhost:4334/hello”)
(d/create-database db-uri)
bin/run -m datomic.peer-server -h localhost -p 8998 -a myaccesskey,mysecret -d hello,datomic:dev://localhost:4334/hello
[com.datomic/client-pro “0.8.28”]添加到了我的依赖项中运行lein ring server时出现此错误：
Caused by: java.lang.ClassNotFoundException: org.eclipse.jetty.util.thread.NonBlockingThread
答案 0 :(得分：0)
不是直接的答案，但是，如果您只是想快速入门Datomic，可以在这里克隆Tupelo Datomic仓库：
https://github.com/cloojure/tupelo-datomic
它包括Datomic Free的预配置版本。只需运行lein test即可查看实际效果。然后，您可以添加自己的代码。
您可能只需要Erwin的答案。另一种可能性是，您可能需要在特定版本中添加传递依赖，并在其他版本上使用:exclude。另请注意，在project.clj中，重要的部门必须列在文件的顶部，因为这些部门的版本（及其过渡部门的版本）将被覆盖取决于稍后指定的版本。
在project.clj中，我有一个项目的Lein Deps：

您还可以看到我必须排除Jetty，以防止传递依赖引入错误的版本，然后专门添加我想要的版本。
