Access Stage results in Workflow/ Pipeline plugin

Question

I have a pipeline with different stages. I want the current job to check how many stages have passed in the previous build and log it in the console?

Here is a sample code to iterate all flow nodes and get whatever information you want:

import org.jenkinsci.plugins.workflow.graph.FlowGraphWalker
import org.jenkinsci.plugins.workflow.graph.FlowNode

try {
    // just for demo, a success step and a failure step
    node {
        sh 'true'
        sh 'false'
    }
} finally {
    FlowGraphWalker walker = new FlowGraphWalker(currentBuild.rawBuild.getExecution())
    for (FlowNode flowNode: walker) {
        // do whatever you want with flowNode
        echo flowNode.dump()
    }
}
