Maven java 错误编译

Question

请帮助我理解此错误。顺便说一句，这不是最新版本的 presto。我们正在使用自己的设置对其进行自定义。当我构建它时，收到以下错误：

[ERROR] Failed to execute goal org.apache.maven.plugins:maven-compiler-plugin:3.0:compile (default-compile) on project presto-connector:     Compilation failure: Compilation failure:

Answer 1

你的代码上几乎没有错误。正如错误日志所说：

• S3PartitionManager 711号线。
• BackgroundS3SplitLoader 267、330、357、382路

您正在将对象转换为不兼容的类型。

例如：将com.facebook.presto.hive.HiveType转换为com.facebook.presto.spi.type.Type是不兼容的。
