Commented: (WAGONFTP-8) ArrayIndexOutOfBoundsException upon deploy

JIRA jira@codehaus.org
    [ http://jira.codehaus.org/browse/WAGONFTP-8?page=comments#action_54058 ]

John Wells commented on WAGONFTP-8:
-----------------------------------

The AIOOB exception can be fixed by changing the following line:

(@ approximately line 329 in file FtpWagon.c - the 1.0-alpha-5 version)

if ( ftpFiles == null  )
 {
   throw new ResourceDoesNotExistException( "Could not find file: '" + resource + "'" );
 }

long contentLength = ftpFiles[0].getSize();

to this:

(@ approximately line 329 in file FtpWagon.c - the 1.0-alpha-5 version)

if ( ftpFiles == null  || ftpFiles.length <= 0)
 {
   throw new ResourceDoesNotExistException( "Could not find file: '" + resource + "'" );
 }

long contentLength = ftpFiles[0].getSize();

I have no idea whether or not this will fix the underlying problem (that the previous line is returning an empty array) or not.  I can't seem to make my ant-task pick up my local:

1.0-alpha-6-SNAPSHOT

version.  I keep getting the following error:

Buildfile: build.xml

deploy:
[artifact:install-provider] Installing provider: org.apache.maven.wagon:wagon-ftp:jar:1.0-alpha-6-SNAPSHOT

[artifact:deploy]

I would love to help out more if someone could tell me how to make the ant-task pick up my newer version of the plugin properly.  Or I can spend time and figure it out myself.
