Log:
[FIXED JENKINS-47159] Set proper vargs location

We shouldn't be starting looking for vargs until we've got to the
index of the last parameter type and that last parameter type is an
array. So...tada.

I can confirm that this bug is in script-security-plugin v.1.26 as well as 1.29.1 running on Jenkins v. 1.651.3.

Code:

def PARAM = "param"
build.addAction(new ParametersAction(
 new StringParameterValue('PARAM', PARAM)
));

as well as:

build.addAction(new ParametersAction(
    new StringParameterValue("param1", param1),
    new StringParameterValue("param2", param2),
));

yields following error:
ERROR: Build step failed with exception
java.lang.IllegalArgumentException
: array element type mismatch

Workaround

I am attempting to overcome this issue by calling the only constructor that is not overloaded – the two parameter ParametersAction(List<ParameterValue> parameters, Collection<String> additionalSafeParameters) constructor.

ParameterValue[] params = [
		new StringParameterValue("param1", param1),
		new StringParameterValue("param2", param2),
]
String [] safeParams = []
// XXX because of JENKINS-47159
build.addAction (new ParametersAction(params, safeParams));

I think that this is a severe issue for all of the Jenkins users that use Groovy scripting.
Hell, this usage is even written in the first example on the official jenkins-groovy-plugin page.

Yes, I did. 

this is happening in an unreleased version and is caused by a fix introduced for JENKINS-44557

So not really a duplicate.

Have you checked the open issues in this component for duplicates?

Yep,

there's an issue.

In the following script:

def t = Hudson.instance.getJob("test")
params = [new BooleanParameterValue ('FLAG',true)]
parmAction = new ParametersAction(params)
future = t.scheduleBuild2(0, new Cause.UpstreamCause(build), parmAction)

I'm getting:

org.codehaus.groovy.runtime.typehandling.GroovyCastException

Because we should be passing in the varargs position (fixedLen) and not the arrayLength
