Jenkins / Bug JENKINS-38571
Can't get Axes result in pipeline
Issue Type: Bug Bug
Assignee: Kohsuke Kawaguchi
Components: build-pipeline-plugin, matrix-project-plugin
Created: 2016/Sep/28 12:46 PM
Environment: Jenkins 2..7.4, Build Pipeline Plugin 1.5.4, Matrix Project Plugin 1.7.1
Labels: pipeline plugin matrix exception
Priority: Minor Minor
Reporter: Estrada Matthieu

Hello,

When I attempt to access some value or object of Matrix Job in Pipeline script, I often had the following error:

java.io.NotSerializableException: hudson.matrix.MatrixRun

Sometimes I've solved this problem (cause my code is not good or not correctly formed) or bypass by other ways. But in this case, I can't found a solution. here is my pipeline code :

node {
    def job = jenkins.model.Jenkins.instance.getItem("Corealpi_Core")

    // It seems problem comes here    
    def axes = job.getLastBuild().getRuns()
    
    for(int i = 0; i < axes.size(); i++) {
    	println("${axes[i].getResult()}")
    }
}

If I execute this in script console, that's working fine.

Is there a workaround for this problem ? Or I make a mistake somewhere ?

Hello,

When I attempt to access some value or object of Matrix Job in Pipeline script, I often had the following error:


{code:java}
java.io.NotSerializableException: hudson.matrix.MatrixRun
{code}


Sometimes I've solved this problem (cause my code is not good or not correctly formed) or bypass by other ways. But in this case, I can't found a solution. here is my pipeline code :

{code:java}

node {
    def job = jenkins.model.Jenkins.instance.getItem("Corealpi_Core")

    // It seems problem comes here    
    def axes = job.getLastBuild().getRuns()
    
    for(int i = 0; i < axes.size(); i++) {
     println("${axes[i].getResult()}")
    }
}
{code}

If I execute this in script console, that's working fine. Here is the full log :

Jesse Glick resolved as Not A Defect
 

All references to potentially non-Serializable objects, including most Jenkins API model objects, must be encapsulated in a method marked @NonCPS.

Since such idioms will be rejected by sandboxed scripts, the norm in secured instances, it is generally advisable to create a safe façade in a global library.

For this kind of access normally you would want to use the return value of a build step, which provides sandbox-safe information, though currently it does not provide special support for matrix projects (would be a separate RFE).

Ok, with @NonCPS it's working great. Thanks for help.
