The guava version is not compatible with spring-data-cassandra library

[JCL38-ORANGE]

Hello,

The last cassandra-unit release brings an upgrade to a most recent guava release.
...
com.google.guava
guava
21.0
...
This guava version is not compliant with the old cassandra datastax driver which is still included in the stable spring-data-cassandra framework (1.5.7).
https://jira.spring.io/browse/DATACASS-424
spring-projects/spring-boot#8809

I need to downgrade the guava version to 18.0 in order to use both cassandra-unit and spring-data-cassandra.
...
com.google.guava
guava
18.0
...
Regards,
Jean-Christophe.

I guess this is something the user will have to exclude in the pom.xml.

The cassandra-all library references classes that have been removed from Guava, for example com.google.common.base.CharMatcher.DIGIT. This causes runtime errors like

java.lang.NoClassDefFoundError: Could not initialize class org.apache.cassandra.io.sstable.format.SSTableFormat$Type

Filed CASSANDRA-15245

In my environment, I could build using guava 25.1 without an error. But, the error occurred using guava 26.0.

Plus one to this issue but with Java 30.1-jre.

This issue been open for almost 4 years, and the only workaround offered is to use an ancient Guava version? There's also another long standing ticket for supporting Java 11, which has been around for 3 years. The general vibe I get from using the cassandra-unit library is "we have created a library, thanks, $^% you very much".
