I was addicted to the NoSuchMethodError in Cloud Endpoints

Overview

When creating Rest API using Cloud Endpoints in GAE / Java environment I was proceeding with the implementation by looking at Google Official Tutorial. At one point, I got a NoSuchMethodError and it stopped working properly.

How to improve

Here's how to improve it in my environment.

The problem was that there were multiple jar files in the library called jackson-core, causing inconsistencies. At the same time as CloudEndpoints, Jacson core was described in the pom.xml file to create a dependency, which seems to have caused an inconsistency.

I removed the jackson-core related library that I added independently because I wanted to use ObjectMapper, and tried deploying it again. It was confirmed that the processing was performed correctly.
