Scripted Pipeline is a domain-specific language based on Groovy, most Groovy syntax can be used in Scripted Pipeline without modification.
Executing in parallel
The example above runs tests across two different platforms in a linear series. In practice, if the make check execution takes 30 minutes to complete, the "Test" stage would now take 60
minutes to complete!
Fortunately, Pipeline has built-in functionality for executing portions of
Scripted Pipeline in parallel, implemented in the aptly named parallel step.
Refactoring the example above to use the parallel step:
// Script //
stage('Build') {
/* .. snip .. */
}
stage('Test') {
parallel linux: {
node('linux') {
checkout scm
try {
unstash 'app'
sh 'make check'
}
finally {
junit '**/target/*.xml'
}
}
},
windows: {
node('windows') {
/* .. snip .. */
}
}
}
// Declarative not yet implemented //Instead of executing the tests on the "linux" and "windows" labelled nodes in series, they will now execute in parallel assuming the requisite capacity exists in the Jenkins environment.
