Solution

The cause of your error:

Caused by: java.net.BindException: Address already in use: bind

Explanation: As a default, Jenkins uses the port 8080 (like many other web applications do, too). Obviously, you already have another application listening on port 8080.

So you should bind Jenkins to another port. See Starting and Accessing Jenkins for more information. For example, you can start with

java -jar jenkins.war --httpPort=8081
