Camel SFTP can't establish connection - apache-camel

Question

I have the SFTP server up in one docker container available at localhost:2222 with user user/pass
Trying to establish connection in other one via camel 2.22.0 route like
from("sftp:user#localhost:2222/sftp/in?password=pass"))
.log("${file:name}");
But cannot connect because of
Error auto creating directory:/sftp/in due Cannot connect to sftp://user#localhost:2222. This exception is ignored.
org.apache.camel.component.file.GenericFileOperationFailedException: Cannot connect to sftp://pms#localhost:2222
at org.apache.camel.component.file.remote.SftpOperations.connect(SftpOperations.java:144)

Caused by: com.jcraft.jsch.JSchException: java.net.ConnectException: Connection refused (Connection refused)
at com.jcraft.jsch.Util.createSocket(Util.java:394)
Got that after moving from camel 2.18.2 to camel 2.22.0.
Is it possible to fix?

Answer 1

We upgraded from camel 2.20.0 to camel 2.22.0 during development. After upgrading we could not reach camel from another server. Same problem, Connection Refused. We downgraded back to 2.20.0 and things started working again

Answer 2

I have also had this issue and resolved it by adding camel-ftp dependency:
<dependency>
<groupId>org.apache.camel</groupId>
<artifactId>camel-ftp</artifactId>
<version>3.16.0</version>
</dependency>
Please check dependency version that works for you here: https://mvnrepository.com/artifact/org.apache.camel/camel-ftp
