Groovy triggering build with both default and new parameters

[Sverre Moe]

Groovy Code for triggering a build with a parameter

def params = 

[

    new StringParameterValue('UPSTREAM_TRIGGER_CAUSE', 'true')

]

def paramsAction = new ParametersAction(params)

def cause = new UpstreamCause(build)

def futureTask = project.scheduleBuild2(project.quietPeriod, cause, paramsAction)

I have configured parameters for each projects with default values. When I supply this one extra parameter with scheduleBuild2 the other configured parameters are not set. Thus getting:

 > git rev-parse ${BUILD_BRANCH}^{commit} # timeout=10
ERROR: Couldn't find any revision to build. Verify the repository and branch configuration for this job.

I reckon I have to first get the configured parameters from the project, then add the new one. 

Just not sure how. I can read the properties with

def property = project.getProperty(ParametersDefinitionProperty.class)

But that will not give me a map of key/value for each property.

I have tried the following solution:

def property = project.getProperty(ParametersDefinitionProperty.class)

def jobParams = property.getParameterDefinitions();

def newParam = new StringParameterValue('UPSTREAM_TRIGGER_CAUSE', 'true')

jobParams.add(newParam)

def parametersAction = new ParametersAction(jobParams)

def cause = new UpstreamCause(build)

def futureTask = project.scheduleBuild2(project.quietPeriod, cause, parametersAction)

However it gets stuck on scheduleBuild2 and does not return.

Seems that was totally wrong.

My latest attempt seems to work:

def params = []

def extraParameterValue = new BooleanParameterValue('UPSTREAM_TRIGGER_CAUSE', true)

params.add(extraParameterValue)

def parametersDefProp = project.getProperty(ParametersDefinitionProperty.class)

parametersDefProp.getParameterDefinitions().each { param ->

    def parameterValue = param.getDefaultParameterValue()

    params.add(parameterValue)

}

def parametersAction = new ParametersAction(params)

def cause = new UpstreamCause(build)

def futureTask = project.scheduleBuild2(project.quietPeriod, cause, parametersAction)
