eq operator not found

[Abu Rashid Ibrahim]

Hi, I am just tryin to follow the initial tutorial code and am getting an error thart the eq function is not found, used as an infix call to findOne().

Is there something I need to add a reference to or import for this? I can see eq in org.litote.kmongo.MongoOperator but that seems to be an enum not a function.

Code is just straight off your intro page:

import org.litote.kmongo.* //NEEDED! import KMongo extensions

data class Jedi(val name: String, val age: Int)

val client = KMongo.createClient() //get com.mongodb.MongoClient new instance

val database = client.getDatabase("test") //normal java driver usage

val col = database.getCollection<Jedi>()

col.insertOne(Jedi("Luke Skywalker", 19))

val yoda : Jedi? = col.findOne(Jedi::name eq "Yoda")  

Thanks,

Abu Rashid.

Hi,

The eq infix function is in org.litote.kmongo package http://litote.org/kmongo/dokka/kmongo/org.litote.kmongo/kotlin.reflect.-k-property/eq.html

You can try

import org.litote.kmongo.eq

but * should work too.

Doesn't exist for me. I'm using 3.6.2, is that why?

When I try to use 4.0.2 I get the error:

Cannot inline bytecode built with JVM target 1.8 into bytecode that is being built with JVM target 1.6. Please specify proper '-jvm-target' option

In kmongo doc:

Starting from 4.0, minimum supported jvm is now 1.8 (was 1.6). You have to set the property jvmTarget to 1.8 (or more) in your gradle or maven descriptor

look at https://stackoverflow.com/questions/49509330/kotlin-compile-to-java-1-8 for gradle & https://kotlinlang.org/docs/reference/using-maven.html for maven

Thank you kindly, that has resolved the issue.

I tried searching for this on google but all resolutions I could find were for Android only, and therefore didn't work for me.
