Exception in thread "Jenkins initialization thread"

To resolve this issue, Please follow the below steps.

1. Reach out to install folder of Jenkins: C:Program Files (x86)Jenkins


2. Open jenkins.xml file in note pad.


3. To change the port -Search-> --httpPort=8080 and change 8080 to 8383.


4. Open command prompt and run find your system IPv4 Address. (E.g.- 172.161.46.173)


5. Paste IP along with jenkins port into browser (E.g.- 172.161.46.173/8383) and hit Enter.


6. It ask for Administration password:
   Get that password from: C:Program Files (x86)JenkinssecretsinitialAdminPassword file


7. Again It asked for plugin installation. Select the default.


8. Once installation done - Click on continue.


9. Now, Set username and password - Here, You are good to go and use jenkins.

The root cause is that the requested http port is used by a different application if you started jenkins with command line: java -jar jenkins.war --httpPort=8080 change it to e.g.: java -jar jenkins.war --httpPort=8383

the root cause is default port 8080 is already being used, so in order to use it again, you need to kill PID used by that port, and then you can run again.

C:Program FilesJavajdk1.8.0_191bin>netstat -ano|find "8080"

  TCP    0.0.0.0:8080           0.0.0.0:0              LISTENING       5256

  TCP    [::]:8080              [::]:0                 LISTENING       5256



C:Program FilesJavajdk1.8.0_191bin>taskkill /PID 5256 /F

SUCCESS: The process with PID 5256 has been terminated.

then you can start again
