Gson is embedded within the jar causing version compatibility with Spring Boot

[ashisjena]

Newer spring is expecting the GsonBuilder to have method "setStrictness" in their GsonAutoConfiguration class. But as Gson is not used as an dependency rather is embbeded in the jar.

Error logs:

java.lang.NoSuchMethodError: 'com.google.gson.GsonBuilder com.google.gson.GsonBuilder.setStrictness(com.google.gson.Strictness)'

The called method's class, com.google.gson.GsonBuilder, is available from the following locations:

jar:file:/Users//.m2/repository/com/datasonnet/datasonnet-mapper/3.0.0/datasonnet-mapper-3.0.0.jar!/com/google/gson/GsonBuilder.class
jar:file:/Users//.m2/repository/com/google/code/gson/gson/2.11.0/gson-2.11.0.jar!/com/google/gson/GsonBuilder.class

Correct the classpath of your application so that it contains compatible versions of the classes org.springframework.boot.autoconfigure.gson.GsonAutoConfiguration$StandardGsonBuilderCustomizer and com.google.gson.GsonBuilder

Expected:
The Gson should be added as an maven dependency instead of copying the class files to the jar of the datasonnet-mapper.
