Spring Boot: MongoDb: Exception: NoSuchMethodError: com.mongodb.client.MongoCollection.insertOne(java.lang.Object)

Question

Prologue:

I have researched this topic from the stackoverflow answers. All answers were pointed towards the dependency conflict, which in my case doesn't seem to be true. (if i am not missing anything)

Problem:

I am getting this exception during runtime when i use the MongoTemplate implementation save or insert

mongoTemplate.save(saveObject, COLLECTION)
mongoTemplate.insert(insertObject, COLLECTION)

There are no build issues or compilation issues. The save or insert methods internally call MongoCollection<TDocument>.insertOne(TDocument doc) for my use case. If I implement this like below, it works fine :

MongoCollection<Document> collection = mongoTemplate.getCollection(COLLECTION);
collection.insertOne(docToSave);

Debug:

Also, If i put a debug point at org.springframework.data.mongodb.core.MongoTemplate

collectionToUse.insertOne(dbDoc);//exception is thrown from here

and execute it manually from the debugger, it works!

So there is no way that the Implementation is missing and judging from the gradle dependencies map, there seems to be no conflict as well.

here is my dependency structure:

Answer 1

Removing spring-integration-mongodb and mongo-java-driver and using just spring-boot-starter-data-mongodb fixed the issue! I think it's safe to assume that spring is looking for a compatible org.mongodb:mongo-driver-sync implementation. However, I would like to hear other's opinion on this one.

FYI, spring-boot-starter-data-mongodb brings down all the implementations the project required, including the implementations from org.mongodb:mongo-java-driver as org.mongodb:mongo-driver-sync.
