Build failed - gradle

Question

I am building my application using Gradle. I am unable to build because it is showing "An error occurred starting the Tomcat server" I am actually trying to build an application provided by the spring tutorial http://spring.io/guides/tutorials/web/

I have checked that no other process is running on port 8080

can somebody suggest what am I doing wrong

Here is the full stack trace of error

Started Tomcat Server
The Server is running at http://localhost:8080

BUILD FAILED

Answer 1

Your problem is surely related with the stop port. Since you are not setting it, tomcat is using the default one (8081). Try to change it:

tomcatRunWar.stopPort = 8181

Answer 2

the problem is with the build.gradle file

maketomcatRunWar.contextPath = ''

to

tomcatRunWar{
    contextPath = ''
    httpPort = 8080
    stopPort = 8191 
}
