I've been playing around with this as well, there doesn't seem to be a lot
of documentation around using parallel in declarative pipelines, but this
seems to work for us:
stage('Code analysis') {
steps {
parallel (
lint: {
//run lint
},
phpmd: {
//run phpmd
},
phpcs: {
//run phpcs
}
)
}
Or if you're using older scripted pipelines then it'd be something like:
stage('Code analysis') {
parallel (
phpmd: {
//run phpmd
},
phpcs: {
//run phpcs
},
phploc: {
//run phploc
},
)
}
I hope this helps
