创建BatchTableEnvironment报错

flink 1.11.2版本，我写了个WordCountTable例子，代码如下：
public class WordCountTable {
    public static void main(String[] args) throws Exception {
        ExecutionEnvironment env = ExecutionEnvironment.getExecutionEnvironment();
        BatchTableEnvironment tEnv = BatchTableEnvironment.create(env);
        DataSet<WordCountTable.WC> input = env.fromElements(new WC("Hello", 1L),。。。。
运行报错：
Exception in thread "main" org.apache.flink.table.api.TableException: Create BatchTableEnvironment failed.
at org.apache.flink.table.api.bridge.java.BatchTableEnvironment.create(BatchTableEnvironment.java:517)

pox table相关依赖：
