If the streaming-examples module uses the <classifier> tag to add the
test-core dependency then we should change it into <type> tag as
recommended by maven [1]. Otherwise it might come to build failures if the
install lifecycle is not executed.
The dependency import should look like:
<dependency>
<groupId>org.apache.flink</groupId>
<artifactId>flink-streaming-core</artifactId>
<version>${project.version}</version>
<scope>test</scope>
<type>test-jar</type>
</dependency>
