how to end a jenkins build with a specific parameter - jenkins

Question

I trigger a build called testAUT with parameter FRACTURE_NO = 15. I trigger the same build with the same parameter.
I want when that happens that the earlier build gets killed. How can I do that using Jenkins? I want to be able to end a build with the same parameter as the current build.

If you're OK with using the Groovy Plugin and Jenkins Rest Api, here are the steps needed to do what you want.
Install the Groovy Plugin.
Go to the job's configure page.
Add the 'fracture_no' build parameter with default value of 125.
Enable 'Execute concurrent builds if necessary' in the General section
Add a 'Execute Groovy script' build step as the first step in the job
Add the following code to the groovy step
def parameterName = "fracture_no";
def jenkinsUrl = System.getenv('JENKINS_URL');
def buildNumber = System.getenv('BUILD_NUMBER').toInteger();
def jobUrl = jenkinsUrl + "job/" + System.getenv('JOB_NAME');
def buildNumberUrl = jobUrl + "/" + buildNumber;
def myParameter = System.getenv(parameterName);
def projectXml = new XmlSlurper().parseText(new URL(jobUrl + "/api/xml").getText());
projectXml.build.each {
def previousBuildNumber = it.number.text().toInteger();
if(previousBuildNumber < buildNumber)
{
def previousBuildNumberUrl = jobUrl + "/" + previousBuildNumber;
def jobXml = new XmlSlurper().parseText(new URL(previousBuildNumberUrl + "/api/xml").getText());
if(jobXml.building.text() == "true")
{
jobXml.action.parameter.each {
if(it.name.text() == parameterName) {
if(it.value.text() == myParameter) {
def url = new URL(previousBuildNumberUrl + "/stop");
def connection = url.openConnection();
connection.setRequestMethod("POST");
connection.connect();
connection.content.text;
println "Stopping " + previousBuildNumber;
}
}
}
}
}
}
Add another build step that takes a long time. If you just want to test, then add the following Windows Batch Command step that sleeps for 100 seconds.
ping 127.0.0.1 -n 100 > nul
Kick off the job twice using the default parameter value of 125 (or as many times as you want).
Everything but the latest build should be stopped.
