I have a Maven build where once the packaging is complete, I attempt to send some files from the packaging to an FTP server using a specific profile. The problem is, I consistent get a Maven failure whenever I try this:
Failed to execute goal org.apache.maven.plugins:maven-antrun-plugin:1.3:run
(deploy) on project xxx.xxx.xxx.xxx: An Ant BuildException has occured:
Could not login to FTP server
This is quite confusing because I am able to log into the FTP server using FileZilla and the same credentials I am using for the Maven Ant build task without any problems (on the same machine). I am also able to transfer files in both directions via FileZilla without any problems either.
This used to work fine before I did a routine server restart recently. My FTP server is a DigitalOcean droplet with the standard Ubuntu OS and VSFTPD installed.
My pom.xml is as follows:
...
<profile>
<id>publish-product</id>
<activation>
<activeByDefault>false</activeByDefault>
</activation>
<build>
<plugins>
<plugin>

<artifactId>ant-commons-net</artifactId>
<version>1.10.9</version>
</dependency>
</dependencies>
</plugin>
</plugins>
</build>
<profile>
...
The Maven build is executed using:
mvn -U -DskipTests clean package -Ppublish-product
Does anyone know what might be happening to prevent the Ant FTP task from running?
The full output of the Ant task is as follows:
[ERROR] Failed to execute goal org.apache.maven.plugins:maven-antrun-plugin:1.3:run (deploy) on project xxxx.xxxx.xxxx.xxxx: An Ant BuildException has occured: Could not login to FTP server -> [Help 1]

"Could not login to FTP server" error indicates that your credentials are wrong. The error is issued when FTPClient.login fails.
I see that you have validated that you have the correct credentials by authenticating with a GUI FTP client. So chances are that there are some special characters in the credentials that may need some escaping or special treatment.
