using JacocoMerge throws error "You can't map a property that does not exist: propertyName=destFile"

After upgrading Gradle from 1.6 to 1.7-rc-1, Gradle fails to evaluate build files with JacocoMerge tasks.

• What went wrong:
  A problem occurred evaluating root project 'gradle-test'.
  > Failed to notify action.
  > You can't map a property that does not exist: propertyName=destFile

build.gradle:

apply plugin: 'jacoco'

task merge(type: JacocoMerge) {
}

This problem is probably caused by [JacocoPlugin]([1]https://github.com/gradle/gradle/blob...), which is using destFile instead of destinationFile.
