error in dsl combineSpec... about kotlin-jpa-specification-dsl HOT 4 OPEN

Ah damn, ok I'll take a look. Can you confirm you're using the latest version i.e. 2.0.0-rc.1?
I'm just about to start updating our 50 odd APIs to Spring Boot 2 so this will bite me as well!

@kimyoon21 Are you using the latest version (https://github.com/consoleau/kotlin-jpa-specification-dsl/releases/tag/v2.0.0-rc.1)

If not, are you able to reproduce in this projects tests? That compilation error looks like breaking in your own code (package is app.foodin.entity.common)

Hi James,

Using
kotlinVersion = "1.3.50"

Thanks

Type inference failed: inline fun <reified T> combineSpecification(specs: Iterable<Specification<T#1 (type parameter of app.foodin.entity.common.combineSpecification)>?>, operation: Specification<T#1>.(Specification<T#1>) -> Specification<T#1>): Specification<T#1>
cannot be applied to
(Iterable<Specification<T#2 (type parameter of app.foodin.entity.common.and)>?>,KFunction2<Specification<T#2>, @ParameterName Specification<T#2>, Specification<T#2>>)

When I build it, this error occurs.
I am using Kotlin 1.3.61 and spring boot 2.2.4

inline fun <reified T> combineSpecification(specs: Iterable<Specification<T>?>,
                                            operation: Specification<T>.(Specification<T>?) -> Specification<T>?): Specification<T> {
    return specs.filterNotNull().fold(emptySpecification()) { existing, new -> existing.operation(new)!! }
}
