Example of using JenkinsClient from bryantrobbins/jenkinsutils

Batch.groovy

// Get credentials and URL for Jenkins server from args
// This constructor builds URL of "http://host:port/path", e.g., localhost, 8080, "" for default install
jenkinsClient = new JenkinsClient(jenkinsHost, jenkinsPort, jenkinsPath, jenkinsUser, jenkinsPass)

// Also Process input arguments (args) to get any global params for Jenkins job

for(int i=0; i<batchSize; i++){
        
        // update/obtain job-specific params
        
        // build Map of params
        // I have only used text params, but perhaps others supported via Jenkins Remote API
        def jobParams = new HashMap<String, String>();
        jobParams.put("PARAM_A", param_a)
        jobParams.put("PARAM_B", param_b)
        jobParams.put("PARAM_C", param_c)
        jobParams.put("PARAM_D", param_d)
        jobParams.put("PARAM_E", param_e)
        
        // Use Jenkins client to launch job
        jenkinsClient.submitJob("MySingleJob", jobParams)
