java.lang.NoClassDefFoundError：org / apache / commons / vfs / FileSelector

Question

我正在嘗試調用使用Kettle Pentaho jar編寫的Java方法。 同時調用它拋出這樣的錯誤...

嚴重：路徑為[/ sakti-backup-restore]的上下文中servlet [spring]的Servlet.service（）拋出異常[處理程序處理失敗； 嵌套異常是java.lang.NoClassDefFoundError：org / apache / commons / vfs /

有什么辦法嗎？

Answer 1

在我看來，您的類路徑中缺少commons-vfs 。

<dependency>
    <groupId>org.apache.commons</groupId>
    <artifactId>commons-vfs2</artifactId>
    <version>2.1</version>
</dependency>
