hive 3.1.3 集成iceberg 1.7.2创建Iceberg表报错如下：

看提示是说当前版本iceberg采用java 11编译，但本地为java 8，看官网release信息证实如此，

1.7.0 release🔗
Apache Iceberg 1.7.0 was released on November 8, 2024.
The 1.7.0 release contains fixes, dependency updates, and new features. For full release notes please visit Github. An abridged list follows
Deprecation / End of Support
Java 8

Build
Build for Java 11 (#10849) - Removal of Java 8
Build: Add checkstyle rule to ban assert usage (#10886)
Support building with Java 21 (#10474)

在此有两种解决方案，可以升级到Java11或者Java17，但涉及到影响范围比较大，谨慎操作。另一种则是降低Iceberg版本，但无法体验到Iceberg的一些最新特性。在此选择第二种。此外，有条件的朋友可以自己编译源码。
