I am newbie to Flink, When I use cmd `mvn clean install -DskipTests -Dfast`, I got error info "[ERROR] Failed to execute goal org.apache.maven.plugins:maven-compiler-plugin:3.8.0:compile (default-compile) on project flink-table-api-java: Compilation failure [ERROR] /Users/snow_young/secrect/opensource/flink/flink-table/flink-table-api-java/src/main/java/org/apache/flink/table/operations/utils/OperationTreeBuilder.java:[560,85] 未报告的异常错误X; 必须对其进行捕获或声明以便抛出"
Sorry for chines error info. I dig into stackoverflow, I think that is answer: https://stackoverflow.com/questions/25523375/java8-lambdas-and-exceptions. Firstly, I check my java, and download again, now My java version: java version "1.8.0_91" Java(TM) SE Runtime Environment (build 1.8.0_91-b14) Java HotSpot(TM) 64-Bit Server VM (build 25.91-b14, mixed mode) I use mac 10.12 system. But, I got same error again. I use `.<TableException>orElseThrow(() -> new TableException("Expected string literal as alias.")))` to explicit expose the throwable type, error disappeared. However, too many same errors need to solve. What is the solution? Thx!
