Pi test failing with following error. Im using spring boot 2.7.18 & gradle 6.9

The value for task ‘:pitest’ property ‘mainClass’ is final and cannot be changed any further.

My build.gradle contains:

apply plugin: “info.solidsoft.pitest”

pitest {
    targetClasses = ['com.cti.stan.*']
    enableDefaultIncrementalAnalysis = true
    reportDir = file("${buildDir}/reports/pit/${project.version}")
    outputFormats = ['HTML']
    pitestVersion = '1.4.0'
    timeoutConstInMillis = 10000
    mutationThreshold = 65
    timestampedReports=false
}

build.dependsOn ‘pitest’
