fullMutationMatrix doesn't work with pitest-aggregator

[huanzhoucircle]

Hi, I’m using PIT with pitest-aggregator in a multi-module project and I’d like to enable fullMutationMatrix for complete test coverage. However, I ran into the following error:

2025-09-02T22:37:02.5847076Z [ERROR] Failed to execute goal org.pitest:pitest-maven:1.20.2:report-aggregate (pit-report-aggregate) on project xxx-testcoverageaggreagtor: 
An error has occurred in PIT Test Report report generation. Unrecognized field "killingTests" (class org.pitest.aggregate.MutationXml), not marked as ignorable 
(14 known properties: "indexes", "succeedingTests", "detected", "blocks", "numberOfTestsRun", "status", "killingTest", "sourceFile", "mutatedClass", "methodDescription", "description", "lineNumber", "mutatedMethod", "mutator"])

It seems that when fullMutationMatrix is enabled, the XML report includes a killingTests field, but pitest-aggregator is expecting killingTest. Could you help confirm whether this is a known issue in PIT or if there’s a configuration that can be adjusted to unblock it?
