step 1: create a seed job 
```
String basepath = 'Common/Java/testapp'

String giturl = 'git@bitbucket.org:abc/testapp'

pipelineJob("$basepath/1.Build-Dev-Int") {
logRotator {
numToKeep(10)
artifactNumToKeep(10)
}
parameters {
stringParam('USE_GIT_BRANCH', 'master')
}
throttleConcurrentBuilds {
maxTotal(1)
}

triggers {
scm('H/15 * * * *')
}

definition {
cpsScm {
scm {
git

branches('master')
extensions { }
}
scriptPath('pipeline/pipeline_dev_int.groovy')
}
}
}
}```
step 2 : create pipeline_dev_int.groovy

```@Library('sharedlibrary@master')

node()

remaining groovy script```
 

step 3:     configured shared library in manage jenkins
even though there is no change in repo it is triggering jobs 
 

whenever a branch/ commit made to the shared library even though there is no change in testapp repo it triggering the job for every 15 min and found this in polling history
