Jenkins: groovy DSL: using the ternary operator to distinguish between FreeStyleJob and MatrixJob

groovy, groovydsl, jenkins, jenkins-job-dsl, ternary-operator

Solution

I managed to solve it this way:

def jobInstance = !config.toolchainsBuild ? job("job1") : matrixJob("job2")

jobInstance.with {
    // ... job definition follows
}

I.e., by using the `with` method. This way, the closure is only written once.

Problem

I am trying to write a groovy-dsl script for Jenkins to generate two jobs: - The first job is a FreestyleJob - The second one is a MatrixJob Their definitions are almost the same; there are only minor differences between them. Therefore, I want to reuse most of the job code and I came to the following refactoring scenario (please focus in the fifth line, in the ternary operator): ``` [ ['toolchainsBuild': false], ['toolchainsBuild': true], ].each { Map config -> config.toolchainsBuild ? job("job1") : matrixJob("job2") { // job definition follows...for example: out.println("debug") steps { cmake { buildToolStep {} } } // if (config.toolchainsBuild) { // ... // different actions, depending on the job type // } } } ``` However, this does not work. Proof: `debug` is printed just once in the logfile (it should appear twice, as I want two different jobs to be defined). I also tried to wrap the ternary operator and its operands in parentheses, as in: ``` (config.toolchainsBuild ? job("job1") : matrixJob("job2")) { // ... ``` However, this causes a syntax error: ``` Processing provided DSL script ERROR: (script, line 20) No signature of method: javaposse.jobdsl.dsl.jobs.MatrixJob.call() is applicable for argument types: (script$_run_closure1$_closure2) values: [script$_run_closure1$_closure2@2cb2656f] Possible solutions: wait(), label(), any(), wait(long), label(java.lang.String), each(groovy.lang.Closure) Started calculate disk usage of build Finished Calculation of disk usage of build in 0 seconds Started calculate disk usage of workspace Finished Calculation of disk usage of workspace in 0 seconds Notifying upstream projects of job completion Finished: FAILURE ``` How can I rewrite the above expression to produce two different jobs, depending on the value of the boolean? I believe the problem is related to the usage of the ternary operator with closures, maybe it is not intended to be used this way?
