我試圖用一個罐子生成包含Clojure的JAR文件,Java類文件一個jar文件:Creating one jar file that for execution from Java/Clojure使用一個罐子來構建一個jar文件
繼the instruction,我可能會產生使用one-jar-appgen-0.97.jar
目錄。按照說明,我更換了java源文件,並添加了ThingOne-1.0.0-SNAPSHOT-standalone.jar
運行ant
,它構建的jar文件沒有錯誤,但當我嘗試執行jar文件時收到了錯誤消息。
java -jar build/test-one-jar.jar
test_one_jar main entry point, args=[]
