Hi,
that is a confusing error in my point of view that you will learn to
interpret :-)
The pipeline you wrote is a declarative one and the usage of "def ... " is
something you can do only in scripted pipelines ... hence, what the error
really means is: "You forgot to open a script block".
The fix is just to wrap inside a "script" block that allow to execute
scripted portion inside a declarative pipeline:
pipeline {
agent any
stages {
stage('example') {
steps {
script {
def causes = currentBuild.getBuildCauses()
echo "Causes are ${causes}"
}
}
}
}
}
