How to merge 2 json files into one html report

[hunterabhi212223]

I am running 2 cucumber runner files. One will run all the tests and failed feature will store in a rerun.text file. 2nd runner will be used to rerun failed feature only. In this case i am getting two different json files. is there any way that i can configure to get single HTML report

Jenkins file creating two json files but failing to genarate reports

Build.gradle

}

test {
// Configure rerun.txt file generation
// This example is for Cucumber
systemProperty 'cucumber.options', "--rerun-file=${buildDir}/rerun.txt"
}

// Define task to generate HTML reports using Maven Cucumber Reporting
task generateCucumberReports(type: Exec) {
// Ensure this task runs after tests are executed
dependsOn test

You should find some configuration that is useful for you https://github.com/damianszczepanik/cucumber-reporting/tree/master/src/main/java/net/masterthought/cucumber/reducers

I guess reducing method ReducingMethod.MERGE_FEATURES_WITH_RETEST can be used to merge results into a single html file.
The https://github.com/damianszczepanik/cucumber-reporting/blob/20f378d26e918e05a3945ae282ac52c88d4108bd/src/main/java/net/masterthought/cucumber/reducers/ReportFeatureWithRetestMerger.java#L109C68-L109C109

It is similar to #1044
