Hello,
I'm trying to use ftp-wagon to deploy a plugin to my remote repository, as
described on page 69 of the BBWM book. Here is my POM:
. . .
<extensions>
<extension>
<groupId>org.apache.maven.wagon</groupId>
<artifactId>wagon-ftp</artifactId>
<version>1.0-alpha-6</version>
</extension>
</extensions>
</build>
<distributionManagement>
<repository>
<id>akathist-repository</id>
<name>Akathist Repository</name>
<url>ftp://ftp.9stmaryrd.com/public_html/maven</url>
</repository>
</distributionManagement>
</project>
But I getting this error (running mvn with -X):
[INFO] [deploy:deploy]
[DEBUG] not adding permissions to wagon connection
[INFO]
------------------------------------------------------------------------
[ERROR] FATAL ERROR

An NPE is not very informative. Does anyone have any idea what the problem
is here?
One thing to note: a username/password is required by the ftp server. I
didn't include it in the POM because it wasn't in the book, and what good is
a username/password if it's in the soon-to-be-published POM? I figured wagon
would prompt me or something. Am I mistaken?
Thanks,
Paul
