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

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
