lein uberjar打包后运行程序报错

[naitong Xiao]

今天用clojure写了统计月度Jira需求任务处理的情况的小程序, 在repl下能够正常运行 (
开启一个新的repl，加载main函数所在namespace，然后运行-main)
但是用lein uberjar 打包后，运行一会儿后（已经连上jira rest接口）报错

在stackoverflow上查了一下，又说是jesery-json 没有包含到classpath,  我确认过jar包里面已经包含
觉得可能是clojure这方面的问题， leiningen打包相关

请教一下大家

试一下lein jar之后cp里带上lib/下的jars运行一下？？
或者lein uberjar之后cp里带上那个json库？

看看有没有线索

[naitong Xiao]

嗯，加上cp应该就可以

我知道问题的原因了， rest client library会读classpath*:META-INF/services/javax.ws.rs.ext.MessageBodyReader Writer文件

Lein uberjar 打包在一起同名文件就会覆盖掉

谢谢你的回复

naitong,

我用eclipse 输出runnable jar， 从命令行运行 碰到相同的问题，
请问如何解决？
