ERROR: Build step failed with exception org.codehaus.cargo.container.ContainerException: Failed to redeploy

Question

I have Jenkins installed on my AWS EC2 server, on which the following are installed:

• Maven Integration Plugin
• Deploy to Container Plugin
• Slack Notification Plugin
• GitHub Integration Plugin

... and possibly a few others I cannot remember (because coding)...

I create new freestyle Project, go to its config, and do the following:

• In General, check GitHub project, and enter the Project url
• In Source Code Management, select Git and enter the Repository URL
• In Build Triggers, check GitHub hook trigger for GITScm polling
• In Build, I add build step "Invoke top-level Maven targets", and do the following:
  • Enter clean install in Goals
  • Enter relative path of my project's pom.xml in POM
• In Post-build Actions, I do the following:
  • Archive the artifacts:
  • Deploy war/ear to container:

On my attempt to build the (working) code, it fails, and I get this long stack of info on the console:

java.net.ConnectException: Connection timed out (Connection timed out)

How can I fix this?

My tomcat credentials, located in [tomcat directory]/conf/tomcat-users.xml, are as follows:

<tomcat-users>
        <role rolename="manager-gui"/>
        <role rolename="manager-script"/>
        <user username="tomcatgui" password="password" roles="manager-gui" />
        <user username="project2" password="Z3n1th0x47726f7570" roles="manager-script" />
</tomcat-users>

Answer 1

Since this is a connection time out,

1. Check whether you restarted the tomcat instance after editing the tomcat-users.xml
2. Check whether jenkins has access to tomcat instance.
3. Whether the user credentials are correct

Answer 2

For the same issue, setting port 8084 in server.xml and restarting the Apache worked for me. I replaced all occurrences of 8080 with 8084:

[root@ip-172-31-21-72 conf]# grep 8084 server.xml
     Define a non-SSL/TLS HTTP/1.1 Connector on port 8084
<Connector port="8084" protocol="HTTP/1.1"
           port="8084" protocol="HTTP/1.1"
