As a workaround, instead of setting `any` you can set agent labels conditionally. Something like below.
```
def labels = "Windows"
if (params.RUN_WINDOWS && params.LINUX) {
labels = "windows || linux"
}
pipeline {
agent any // main agent
parameters {
booleanParam( name: 'RUN_WINDOWS' )
booleanParam( name: 'RUN_LINUX' )
}
stages {
stage('Common step') {
...
}
stage("Test") {
parallel {
stage('Windows') {
agent {
label "${labelSelected}"
}
when {
expression { return params.RUN_WINDOWS }
}
stages {
stage('Test Windows') {
...
}
}
}
stage('Linux') { // no agent specified, so will use the main agent
when {
expression { return params.RUN_LINUX }
}
stages {
stage('Test Linux') {
...
}
}
}
}
post {
...
}
}
}
}
```

If you need multiple agents you can declare `agent none` and then declare the agent at each stage.
https://jenkins.io/doc/book/pipeline/jenkinsfile/#using-multiple-agents
From the docs:
pipeline {
agent none
stages {
stage('Build') {
agent any
steps {
checkout scm
sh 'make'
stash includes: '**/target/*.jar', name: 'app'
}
}
stage('Test on Linux') {
agent {
label 'linux'
}
steps {
unstash 'app'
sh 'make check'
}
post {
always {
junit '**/target/*.xml'
}
}
}
stage('Test on Windows') {
agent {
label 'windows'
}
steps {
unstash 'app'
bat 'make check'
}
post {
always {
junit '**/target/*.xml'
}
}
}
}
}
