java.lang.NoClassDefFoundError: com/google/gson/internal/reflect/ReflectionAccessor

[NickKanellos]

Hey, ya'll. Do ya'll know about this?

Cross posting this issue here: https://github.com/IBM/cloudant-java-sdk/issues/253 & https://github.com/IBM/cloudant-java-sdk/pull/236

Describe the bug

java.lang.NoClassDefFoundError: com/google/gson/internal/reflect/ReflectionAccessor
 at com.ibm.cloud.sdk.core.util.DynamicModelTypeAdapterFactory.(DynamicModelTypeAdapterFactory.java:77)
 at com.ibm.cloud.sdk.core.util.GsonSingleton.registerTypeAdapters(GsonSingleton.java:77)
 at com.ibm.cloud.sdk.core.util.GsonSingleton.createGson(GsonSingleton.java:53)
 at com.ibm.cloud.sdk.core.util.GsonSingleton.getGsonWithoutPrettyPrinting(GsonSingleton.java:102)
 at com.ibm.cloud.sdk.core.http.RequestBuilder.bodyContent(RequestBuilder.java:417)
 at com.ibm.cloud.cloudant.v1.Cloudant.postDocument(Cloudant.java:825)

To Reproduce

call com.ibm.cloud.cloudant.v1.Cloudant.postDocument() using

<dependency>
     <groupId>com.ibm.cloud</groupId>
     <artifactId>cloudant</artifactId>
     <version>0.0.36</version>
</dependency>

and

<!-- https://mvnrepository.com/artifact/com.google.code.gson/gson -->
<dependency>
    <groupId>com.google.code.gson</groupId>
    <artifactId>gson</artifactId>
    <version>2.9.0</version>
</dependency>

Unfortunately I can't use an earlier version of GSON because of this: https://github.com/google/gson/issues/1875 and this https://github.com/google/gson/pull/1902

Must gather (please complete the following information):

$ java --version
openjdk 16.0.2 2021-07-20
OpenJDK Runtime Environment Temurin-16.0.2+7 (build 16.0.2+7)
OpenJDK 64-Bit Server VM Temurin-16.0.2+7 (build 16.0.2+7, mixed mode, sharing)

Yes, we're aware that SDKs cannot yet upgrade to gson 2.9.0. The latest version the java core can use is currently 2.8.9, and we have an issue on our backlog to migrate to gson 2.9.0: https://github.ibm.com/arf/planning-sdk-squad/issues/3106

[padamstx]

Version 9.15.5 of the java core has been released which bumps up the gson dependency to 2.9.0.

        }
        params.put("images", list);
        params.put("description", "描述。。。");
        logger.info("----------");
        Product product = Product.create(params);
//        Product product = stripeService.createProduct(params);
        logger.info("-----"+product.toString());
    }

@japhet99 Your problem doesn't appear to be an issue with this particular repository. You must be using gson in a different context.
