GitHub user enjoyy2 closed a discussion: Trying to access FTPS via open file
from GUI failed with NoClassDefFoundError in 2.12
Apache hop 2.12.0 version
jdk 21
when trying to access FTPS file via the URI format with open file dialog in GUI
i receive NoClassDefFoundError, was this library removed in 2.12 ? if i try the
same scenario in 2.8.0 i receive Caused by:
org.apache.commons.net.ftp.FTPConnectionClosedException: Connection closed
without indication. -> which is ok cause atleast it has found the library.
Error browsing to location: 'ftps://xxxxx masked for privacy reasons'
NoClassDefFoundError: org/apache/commons/net/ftp/FTPClient
Root cause: ClassNotFoundException: org.apache.commons.net.ftp.FTPClient

2.12.0 it is placed in actions\ftp\lib
why was the library moved ?
