Maven: copying to FTP throws java.io.IOException: Illegal seek

Question

I have a desktop (centos 7.1) and a ftp server (GF4 is here). And I want to copy files after maven building to ftp server (witch was mounted by nautilus) However I get this:

The file in folder /run/user/1000/gvfs/ftp:host=X.X.X.X,port=XXX/glassfish4/glassfish/domains/domain3/autodeploy/bundles/temp.jar is created but its size=0. Besides when I do manual copy:

cp /home/myuser/temp/target/temp.jar /run/user/1000/gvfs/ftp:host=X.X.X.X,port=XXX/glassfish4/glassfish/domains/domain3/autodeploy/bundles/

every thing is ok. How to fix it?
EDIT1
I created an empty osgi project which contains only activator. Here is the pom

Result is the same - at destination folder hworld-1.0.-SNAPSHOT.jar is created but its size=0.

Answer 1

Using maven-dependency-plugin's copy target you can copy the dependencies available to the plugin at the time of running it, which is before the binary artefacts of your project are available in target folder.

To upload the binary artefacts of your project to FTP, please use the following:

• in your pom:

<project>
  ...
  <distributionManagement>
    <repository>
      <id>ftp-repository</id>
      <url>ftp://repository.mycompany.com/repository</url>
    </repository>
  </distributionManagement>

  <build>
    <extensions>
      <!-- Enabling the use of FTP -->
      <extension>
        <groupId>org.apache.maven.wagon</groupId>
         <artifactId>wagon-ftp</artifactId>
         <version>2.9</version>
      </extension>
    </extensions>
  </build>
  ...
</project>

• in your ~.m2/settings.xml

<settings>
  ...
  <servers>
    <server>
      <id>ftp-repository</id>
      <username>user</username>
      <password>pass</password>
    </server>
  </servers>
  ...
</settings>

Please note that id from pom matches the id in settings.
