从Java将值传递给Jenkins

Question

Is there any way to pass value from Java (maven project) code to Jenkins job?.

Suppose that my java code looks like below.

public void generateRandom(){
    double random = Math.random();
    return random;
}

One of my Jenkins job in the pipeline will execute above code and the value returned by the code needs to be passed to a downstream job. The downstream job is parameterized.

Is it possible to pass the generated random number to the downstream job somehow like this -

${random}

Answer 1

You will have to use a property read operation said like here https://jenkins.io/doc/pipeline/steps/pipeline-utility-steps/#readproperties-read-properties-from-files-in-the-workspace-or-text .

May be you can write the output of java code to some file, and make that input for the next jenkins job.?
