AEMaaCS AEM SDK2025.3.20133.20250325T063357Z-250300 jar fails with gson

I have just upgraded our build to use the latest AEM SDK, however everything that uses JSON now fails to run with the following errors

 

java.lang.NoSuchMethodError: 'void com.google.gson.internal.ConstructorConstructor.<init>(java.util.Map, boolean)'
at com.google.gson.Gson.<init>(Gson.java:218)
at com.google.gson.Gson.<init>(Gson.java:195)

at com.merkle.xp.whitelabel.core.models.MerklePageImplTest.testSeoSiteWithNoSeoData(MerklePageImplTest.java:436)

at java.base/java.util.ArrayList.forEach(ArrayList.java:1541)
at java.base/java.util.ArrayList.forEach(ArrayList.java:1541)
 
The code that does this is new Gson()
 
I can revert back to an older version, however I worry how this will work on the servers.

Got the same issue earlier, I am assuming you are using GSON version 2.8.9 or older in your code. 

Update the version to [2.9.0] and test your code that uses GSON library. Everything should get fixed after this.

Hi @taggatmerkle ,

 

I would assume that you include com.google.code.gson dependency with newer version in your pom.xml.

 

Please check through the Package Dependencies (/system/console/depfinder) latest version that is provided within AEM SDK API dependency. If you bundle is importing another version, please update dependency version to one that is provided with AEM SDK API. 

 

Also double check deprecated API: https://experienceleague.adobe.com/en/docs/experience-manager-cloud-service/content/release-notes/deprecated-removed-features

    Yes we did, but it seems to get ignored since the SDK has a version of gson in it.

     

    To get around this i have removed GSON from all of our code and used ObjectMapper instead.
