Not able to start jenkins localhost:8080

Question

I was able to start jenkins local server by firing below command

java -jar jenkins.war

Initially it worked and I could start the http://localhost:8080/

but suddenly it started giving following error

Now page is just showing loading...loading and in the end page loading fails.

Can anyone please help on this ?

Answer 1

The error message you get, shows that the problem is not in your Jenkins, but that the build of your MySampleProject fails.

So you'll have to either fix the build (fix the problem in the project) or delete the project.
