Jenkinsfile - stop pipeline when catch error - jenkins

Question

I am having a problem with my pipelin in Jenkins.
I perform a path search for files with the specified extension. I then execute php -l with the previously found files.
Everything works ok but I would like if php -l finds an error then build and step go to UNSTABLE state and further execution of the pipeline is stopped.
I managed to do it this way but then build and step are in FAILED state
} catch (Exception e) {
error("${e}")
Part of code my pipeline.
def check(){
stage('Validate files') {
try {
sh "find . -type f -iregex '.*\\.\\(php\\)' | xargs -I % sh -c 'php -l \'%\''"
} catch (Exception e) {
error("${e}")
}
}
}
I hope someone smarter can direct me to a solution :)

Got an example to work but maybe not exactly what you wanted. I used unstable() to mark the stage / build and then checked for the exit code of the sh step to return or continue the pipeline.
There are 2 if's as you need to return outside of a stage to not just return from the stage.
#!/usr/bin/env groovy
try {
node {
def exitCode = 0
exitCode = check()
if (exitCode != 0){
return
}
somethingelse()
}
} catch (Throwable err) { // catch all exceptions
throw err
} finally {}
def check(){
stage('Validate files') {
exitCode = sh script:"exit 1", returnStatus:true
if (exitCode !=0){
unstable('message')
}
}
return exitCode
}
def somethingelse(){
stage('Something'){
echo "somethingelse"
}
}
