Scala 2.11 cannot resolve dependencies

Hey @LiuxyEric, what is your Spark version? Spark 3.0 may not work with these dependencies using Scala 2.11.

For example, Delta core 0.7.0 doesn't support Scala 2.11 (https://mvnrepository.com/artifact/io.delta/delta-core).

If it's possible, use Setl 1.0.0-SNAPSHOT with Spark 3.0 and Scala 2.12. Otherwise, you may try Setl 1.0.0-SNAPSHOT with Spark 2.4 and Scala 2.11

I am using Spark 2.4 and Scala 2.11. It seems that the three dependencies I mentioned on the picture don't have the right version for scala 2.11. I updated my scala version to 2.12 and the problem solved. Thanks for you replay!

Otherwise, another temporary fix is to manually import these three dependencies with the following versions in the sbt file when it's not possible to upgrade from scala 2.11 to 2.12 😄

<dependency>
    <groupId>com.audienceproject</groupId>
    <artifactId>spark-dynamodb_2.11</artifactId>
    <version>1.0.4</version>
</dependency>
<dependency>
    <groupId>io.delta</groupId>
    <artifactId>delta-core_2.11</artifactId>
    <version>0.6.1</version>
</dependency>
<dependency>
    <groupId>com.datastax.spark</groupId>
    <artifactId>spark-cassandra-connector_2.11</artifactId>
    <version>2.5.1</version>
</dependency>

I've added this into the project's readme.

There is indeed something to be improved with the project's pom file and the CI script. I have opened a new issue to continue tracking this problem #173 .
