Hi,

-------------------------------
The NPE occurs in line 122 of class FTPWagon which is:
if ( !ftp.login( username.trim(), password.trim() ) )
So probably the username or password is Null, but I set both in my
settings.xml:
-------------------------------
<settings>
<servers>
<server>
<id>spike</>
<username>maven</username>
<password>maven</password>
</server>
</servers>
</settings>
-------------------------------
Manual login to the FTP server works fine. Any help to sort this out is
appreciated.
