trigger parameterized build doesnt find buildpath in jenkins pipeline job - jenkins

Question

My code dynamically creates a .groovy file which triggers parameterized build inside a parallel step:
def executeParallelBuilds(){
try {
parallel(
build1BUILD: {
def build1BUILD = build job: 'TA/test1', parameters: [string(name: "CPNUM_PARAM", value: 1.141)]
},
build2BUILD: {
def build2BUILD = build job: 'TA/test2', parameters: [string(name: "CPNUM_PARAM", value: 1.141)]
},
failFast: false
)
} catch (e) {
echo "An error ocurred while building"
currentBuild.result="UNSTABLE"
}
}
return this;
Now, I load and execute the groovy file with:
node('master'){
def executeGroovyFile = load buildFilePath
executeGroovyFile.executeParallelBuilds()
}
But it seems that my pipeline cant find the Buildjobs by path.
[Pipeline] }
[Pipeline] // node
[Pipeline] node
Running on master in C:\DevApps\Jenkins\workspace\TA\pipeline_1.0_TEMPLATE
[Pipeline] {
[Pipeline] load
[Pipeline] { (D:\BuildResults_tmp\TA\MBE3\\buildString.groovy)
[Pipeline] }
[Pipeline] // load
[Pipeline] parallel
[Pipeline] [build1BUILD] { (Branch: build1BUILD)
[Pipeline] [build2BUILD] { (Branch: build2BUILD)
[Pipeline] [build1BUILD] build
[Pipeline] [build1BUILD] }
[build1BUILD] Failed in branch build1BUILD
[Pipeline] [build2BUILD] build
[Pipeline] [build2BUILD] }
[build2BUILD] Failed in branch build2BUILD
[Pipeline] // parallel
[Pipeline] echo
An error ocurred while building
[Pipeline] }
What am I doing wrong? I load and execute the .groovy file on my master so that the pipeline should be able to find the other jobs. (Without node declaration I am not able to load and execute)
EDIT: What confuses me is, that I don't get the following error:
No parameterized job named some-downtream-job-name found

Answer 1

There was a problem with the build call.
I saved the whole code as String to a .groovy file. This gave me some struggling with the right notation. (quotes and double qoutes)
After calling my script as:
def build1BUILD = build job: BuildJobNameList[i], parameters: [string(name: "CPNUM_PARAM", value: 1.141)]
everything works fine
