Using latestSuccessfulBuild number in Jenkins groovy job configuration - api

Question

I have a jenkins job and I want to use it's lastSuccessfulBuild number in my Build Flow groovy script.
I can get the last successful build number from Jenkins api at:
http://{JENKINS_DOMAIN}/job/{JOB_NAME}/lastSuccessfulBuild/buildNumber
I tried using groovy's RESTClient in my Build Flow groovy script but when importing the groovyx.net.http.RESTClient library I get syntax error.
Does any one know away of getting around this error or getting the api result in some other way?

Answer 1

maybe this will help you:
import hudson.model.Build;
println(build.getProject().getLastSuccessfulBuild())
for example we have simple build flow groovy script building only one item "JobA". If we want check and print its last successful build we can write such script:
import hudson.model.Build;
def buildA = build("jobA")
println(buildA.getProject().getLastSuccessfulBuild())

Possibly a little overkill, but you can use HttpClient, as all you need is a get request on the url.
Here's one I knocked up from some code I had lying around
Tested it on our own Jenkins instance which has basic auth over ssl.
import org.apache.http.HttpResponse
import org.apache.http.HttpVersion
import org.apache.http.client.HttpClient
import org.apache.http.client.methods.HttpGet
import org.apache.http.client.params.ClientPNames
import org.apache.http.conn.ClientConnectionManager
import org.apache.http.conn.scheme.PlainSocketFactory
import org.apache.http.conn.scheme.Scheme
import org.apache.http.conn.scheme.SchemeRegistry
import org.apache.http.conn.ssl.SSLSocketFactory
import org.apache.http.impl.client.DefaultHttpClient
import org.apache.http.impl.conn.PoolingClientConnectionManager
import org.apache.http.params.BasicHttpParams
import org.apache.http.params.HttpConnectionParams
import org.apache.http.params.HttpParams
import org.apache.http.params.HttpProtocolParams
class LastSuccessfulBuild {
def static main(args) {
println new LastSuccessfulBuild().connect("your.jenkins.com", "443", "/path/to/job/YourJob/lastSuccessfulBuild/buildNumber", "your.user:your-password")
}
def connect(host, port, path, auth) {
def url = new URL("https", host, Integer.parseInt(port), path)
HttpClient client = createClient()
HttpGet get = new HttpGet(url.toURI())
get.setHeader("Authorization", "Basic ${auth.getBytes().encodeBase64().toString()}")
HttpResponse response = client.execute(get)
def status = response.statusLine.statusCode
if (status != 200) {
throw new IOException("Failed to get page, status: $response.statusLine")
}
return response.entity.content.text
}
def createClient() {
HttpParams params = new BasicHttpParams()
HttpProtocolParams.setVersion(params, HttpVersion.HTTP_1_1)
HttpProtocolParams.setContentCharset(params, "UTF-8")
params.setBooleanParameter(ClientPNames.HANDLE_REDIRECTS, true)
SchemeRegistry registry = new SchemeRegistry()
registry.register(new Scheme("http", PlainSocketFactory.getSocketFactory(), 80))
registry.register(new Scheme("https",SSLSocketFactory.getSocketFactory(),443))
ClientConnectionManager ccm = new PoolingClientConnectionManager(registry)
HttpConnectionParams.setConnectionTimeout(params, 8000)
HttpConnectionParams.setSoTimeout(params, 5400000)
HttpClient client = new DefaultHttpClient(ccm, params)
return client
}
}
