Cannot resolve method ‘call(java.lang.String org.apache.flink.table.api.ApiExpression)‘

intellij提示:

Cannot resolve method 'call(java.lang.String, org.apache.flink.table.api.ApiExpression)'

如果强行运行会提示:

Could not resolve over call.

解决方案:

import static org.apache.flink.table.api.Expressions.call;
