NoClassDefFoundError org/apache/poi/ss/usermodel/Workbook

我正在運行一個shell腳本，它調用一個java類來從數據庫獲取一些數據，並用這些數據創建一個excel報告。我得到了線程錯誤異常「主要」 java.lang.NoClassDefFoundError：組織/阿帕奇/ POI/SS時的代碼打在我的Java類下面的線/的usermodel /工作簿：NoClassDefFoundError org/apache/poi/ss/usermodel/Workbook

XSSFWorkbook workbook = new XSSFWorkbook();

這是怎麼了我定義類路徑：

CLASSPATH=${CLASSPATH}:<path-to-jars>/poi-2.5.1-final-20040804.jar 
CLASSPATH=${CLASSPATH}:<path-to-jars>/poi-ooxml-3.11.jar

我驗證了的罐子已經被下載（通過gradle這個），所以想了解我是什麼在這裏失蹤。有人可以幫助我嗎？

堆棧跟蹤：

你爲什麼不使用搖籃建立一個可執行的JAR文件？我不認爲shell腳本需要給你的類路徑 –
