This page describes how to cancel a Jenkins build from ci-tools.
Prerequisites
The Jenkins server connection should be configured as described at here.
Instructions
1. Click Jenkins tab at the bottom of the IDE, then Jenkins toolwindow will be appeared.
2. Click Reload button at the left-top of the toolwindow, then all jobs are appeared at the left pane.
3. Select a job, which is an item with a hammer icon 
at the left pane, then a list of its builds will appear at the center pane. The build with a yellow circle icon is the running build which is cancelable.
4. Select a cancelable build, Stop 
button will be enabled.
5. Click Stop , then the Jenkins server will abort the build.

Please note that aborting a build will take a long time, thus some build remains with the yellow circle icon.
