Jenkins JavaUtil

Jenkins util to get list of all jobs from a Jenkins and trigger all jobs. it is easy with ‘Jenkins API Client for Java’.

This library is just a piece of java code which uses the REST API of Jenkins. This means you can trigger builds, extract informations about jobs or builds etc.

If you are using maven build , please add below dependency in your pom.xml.

<dependency>
  <groupId>com.offbytwo.jenkins</groupId>
  <artifactId>jenkins-client</artifactId>
  <version>0.3.8</version>
</dependency>

If Gradle

compile 'com.offbytwo.jenkins:jenkins-client:0.3.8'

Usage:

JenkinsServer jenkins = new JenkinsServer(new URI("http://localhost:8080/view/<ViewName>/"), "username", "password");
Map<String, Job> jobs = jenkins.getJobs()
This will give a map of all jobs present on given jenkins url location. Now you can do multiple operations for example:
- trigger builds, extract informations about jobs or builds etc

Example 1:

you want details of a particular job and build it:

JobWithDetails job = jobs.get("Job name here").details();
//Build jobs
job.build();
//Build Jobs with parameter
Map <String, String> map=new <String, String>HashMap();
map.put("param1","value1");
map.put("param2","value2");
job.build(param);

Example 2:

Now I am want to build all jobs so how to do it

JenkinsServer jenkins = new JenkinsServer(new URI("http://localhost:8080/view/<ViewName>/"), "username", "password");
//Jobs map to get all jobs
Map<String, Job> jobs = jenkins.getJobs();
//Build Jobs with parameter for example environment ,browser, os
Map <String, String> map=new <String, String>HashMap();
map.put("param1","value1");
map.put("param2","value2");
//Iterate Jobs Map and build each jobs with parameter set in Map "map"
 for ( Map.Entry<String, Job> entry : jobs.entrySet()) {
          if (entry.getValue().details().isBuildable()){
                    entry.getValue().details().build(map));
       }
