error: Static methods in interface require -target:jvm-1.8 using scala 2.11

[Ben Yan]

The following is the environment I use：

1. flink.version: 1.9.0

2. java version "1.8.0_212"

3. scala version: 2.11.12

When I wrote the following code in the scala programming language, I found the following error：

// set up the batch execution environment
val bbSettings = EnvironmentSettings.newInstance().useBlinkPlanner().inBatchMode().build()
val bbTableEnv = TableEnvironment.create(bbSettings)

error: Static methods in interface require -target:jvm-1.8
[ERROR] val bbTableEnv = TableEnvironment.create(bbSettings)

But when I use the java programming language or the version of scala in 2.12, there is no problem.

If I use the version of scala2.11, is there any way to solve this problem? thanks

Best,

Ben

Add this to your scala-maven-plugin

<configuration>
  <args>

  <arg>-target:jvm-1.8</arg>

  </args>

</configuration>
