大家好,stackoverflowers,我有一个spark scala应用程序,它以前在scala 2.11和spark 2.4.4上运行。我正在尝试将scala版本更新到2.12,并将spark更新到3.0.0。当我将所有依赖项更改为scala 2.12兼容版本时,maven构建失败,出现以下错误:
[ERROR] [Error] : missing or invalid dependency detected while loading class file 'Column.class'.
Could not access type DataType in value org.apache.spark.sql.types,
because it (or its dependencies) are missing. Check your build definition for
missing or conflicting dependencies. (Re-run with `-Ylog-classpath` to see the problematic
classpath.)
A full rebuild may help if 'Column.class' was compiled against an incompatible version of
org.apache.spark.sql.types.
还有导入语句 import org.apache.spark.sql.types.DataType
在ide中未解析。
这是我的完整pom.xml:

有人能帮我找出错误吗?我查看了最新的sparkscala文档,似乎类数据类型仍然可用。
