If you want to build a property selector in Jenkins, which
allows you to select an artifact and a depending artifact version, you can’t do
that with default Jenkins property selectors. The following tutorial makes use
of the “Active Choice” plugin, which allows a dynamic generation of selection lists
and access to the other parameter fields in Jenkins.
First we build an artifact selector to select the artifact.
We do this with an “Active Choice Parameter” and a static list. Later we can
replace the static list dynamically with requested artifacts from maven
repository. Use the following groovy script to build the static list, and set
property Name to “artifactId”:
Now we can add an “Active Choice Reactive Parameter” selector.
Referenced Parameter must beset to “artifactId” to get access to the first
defined property field. The following groovy script reads all available
versions of artifact from maven repo and creates a selectable list.
You can copy the groovy script from here:
|
import java.util.regex.Matcher
import java.util.regex.Pattern
import javax.xml.xpath.*
// set target url to artifact versions in you maven repo
URL targetUrl = new
URL("https://mvn.havre.de/repo/de/havre/" + artifactId +
"/");
// resolve HTML version list
HttpURLConnection con = (HttpURLConnection)
targetUrl.openConnection();
con.setRequestMethod("GET");
con.setRequestProperty("Authorization", "Basic
***********************");
int responseCode = con.getResponseCode();
// pars HTML to a simple list
if (responseCode == HttpURLConnection.HTTP_OK) {
BufferedReader
inStream = new BufferedReader(new InputStreamReader(con.getInputStream()));
String inputLine;
StringBuffer
response = new StringBuffer();
while ((inputLine
= inStream.readLine()) != null) {
response.append(inputLine);
}
inStream.close();
Pattern TAG_REGEX =
Pattern.compile("<text>([0-9]*\\.[0-9]*\\.[0-9]*)</text>");
List tagValues = new
ArrayList();
final Matcher
matcher = TAG_REGEX.matcher(response.toString());
while
(matcher.find()) {
tagValues.add(matcher.group(1));
}
Collections.reverse(tagValues);
return tagValues;
} else {
return['GET ' +
targetUrl + ' not worked: ' + responseCode ];
}
