Missing dependencies

[9037568]

Attempting to run the code fragment below (based on this AWS example) reveals missing dependencies.

    RdsDataClient client = RdsDataClient.builder().database(Database)
                           .resourceArn(Database_Resource_ARN)
                           .secretArn(Database_Secret_ARN).build();
    client.forSql("select * from accounts").execute().mapToSingle(File.class);

Error message:

1 year later, still seeing this issue, Has anyone managed to fix this?

com.google.common.base.Strings is part of Guava. Guava is already listed in the dependencies section of build.gradle.

Yes noticed it. And when I added Guava in my Lambda layer, it still failed. then I added it in individual POM.xml within the different lambdas. It worked.

Many dependencies of the RDS client are marked as "runtime" thus will be missed at compile time. Maybe that's your problem?
