Using any SqlDialect returns java.lang.NoSuchFieldError: EMPTY_CONTEXT

Hello, 
I'm facing an issue with Apache Calcite when trying to use the different SqlDialect available.

I am building a Spark-app in Scala using Maven, so in my pom.xml, I define the Calcite dependency as

 
 <dependency>
<groupId>org.apache.calcite</groupId>
<artifactId>calcite-core</artifactId>
<version>1.26.0</version>
</dependency>
 

In my scala app, I import the dialect as import org.apache.calcite.sql.dialect.{PrestoSqlDialect, MysqlSqlDialect, SparkSqlDialect}
Then, when I want to use a dialect, I write val dialect = MysqlSqlDialect.DEFAULT. But, this returns the error java.lang.NoSuchFieldError: EMPTY_CONTEXT

However, when I used val dialect = SqlDialect.DatabaseProduct.MYSQL.getDialect, it works fine. (However, it does not work for SqlDialect.DatabaseProduct.SPARK.getDialect either, for example).

My issue is that I do not want to use the MySqlDialect but rather the Spark and Presto ones. Unfortunately, both of them return the same error java.lang.NoSuchFieldError: EMPTY_CONTEXT.

I don't understand what is happening. I am not defining EMPTY_CONTEXT anywhere in my own code. It is defined in the Calcite code for every dialect, e.g. here for MySqlDialect.

Since I'm using the latest version of Apache Calcite (1.26.0), I should be able to use this code. What am I missing?

Thanks a mil!
