----------------------------------

             Summary: Scala 2.11 maven compile should target Java 1.8
                 Key: FLINK-13896
                 URL: https://issues.apache.org/jira/browse/FLINK-13896
             Project: Flink
          Issue Type: Bug
          Components: Build System
    Affects Versions: 1.9.0
         Environment: 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
