Normally we only need to change Iceberg version in gradle/libs.versions.toml from 1.5.2 to 1.7.1, but Iceberg drop java8 support in 1.7, I'm not sure whether the Iceberg jar could works on Gravitino in Java 1.8 enviroment.

after updating the iceberg version to 1.7.1, there are some compile errors

      > No matching variant of org.apache.iceberg:iceberg-gcp:1.7.1 was found. The consumer was configured to find a library for use during compile-time, compatible with Java 8, preferably in the form of class files, preferably optimized for standard JVMs, and its dependencies declared externally but:
          - Variant 'apiElements' capability org.apache.iceberg:iceberg-gcp:1.7.1 declares a library for use during compile-time, packaged as a jar, and its dependencies declared externally:
              - Incompatible because this component declares a component, compatible with Java 11 and the consumer needed a component, compatible with Java 8
              - Other compatible attribute:
                  - Doesn't say anything about its target Java environment (preferred optimized for standard JVMs)
          - Variant 'runtimeElements' capability org.apache.iceberg:iceberg-gcp:1.7.1 declares a library for use during runtime, packaged as a jar, and its dependencies declared externally:

thanks, but I'm not sure is there any way to make Iceberg 1.7 work on Java8, since Gravitino still supports Java8

Agree, since future updates to iceberg is important, no option but to drop Java 8 support i think
