Terry Wang updated FLINK-13896:
-------------------------------
Description:
When setting TableEnvironment in scala as follwing:
{code:java}
// we can repoduce this problem by put following code in
// org.apache.flink.table.api.scala.internal.StreamTableEnvironmentImplTest
@Test
def testCreateEnvironment(): Unit = {
val settings =
EnvironmentSettings.newInstance().useBlinkPlanner().inBatchMode().build();
val tEnv = TableEnvironment.create(settings);
}
{code}
Then mvn test would fail with an error message like:
error: Static methods in interface require -target:JVM-1.8
We can fix this bug by adding:
<configuration>
<args>
<arg>-target:jvm-1.8</arg>
</args>
</configuration>
to scala-maven-plugin config
> Scala 2.11 maven compile should target Java 1.8
