Zip vs Maven -> Same version different jar files

[rogerbj]

Driver version

v2.1.0.30

Problem description

The jar files in the zip file https://redshift-downloads.s3.amazonaws.com/drivers/jdbc/2.1.0.30/redshift-jdbc42-2.1.0.30.zip and Maven differ. The versions and the number of files are different.

ZIP file:

aws-java-sdk-core-1.12.731.jar
aws-java-sdk-redshift-1.12.731.jar
aws-java-sdk-redshiftserverless-1.12.731.jar
aws-java-sdk-ssooidc-1.12.731.jar
aws-java-sdk-sts-1.12.731.jar
commons-codec-1.15.jar
commons-logging-1.2.jar
httpclient-4.5.14.jar
httpcore-4.4.16.jar
jackson-annotations-2.16.0.jar
jackson-core-2.16.0.jar
jackson-databind-2.16.0.jar
jackson-dataformat-cbor-2.16.0.jar
joda-time-2.12.7.jar
jsoup-1.16.1.jar
redshift-jdbc42-2.1.0.30.jar

Maven:

<dependency>
  <groupId>com.amazon.redshift</groupId>
  <artifactId>redshift-jdbc42</artifactId>
  <version>2.1.0.30</version>
</dependency>

aws-java-sdk-core-1.12.577.jar
aws-java-sdk-redshift-1.12.577.jar
aws-java-sdk-redshiftserverless-1.12.577.jar
aws-java-sdk-sts-1.12.577.jar
commons-codec-1.15.jar
commons-logging-1.1.3.jar
httpclient-4.5.13.jar
httpcore-4.4.13.jar
ion-java-1.0.2.jar
jackson-annotations-2.12.7.jar
jackson-core-2.12.7.jar
jackson-databind-2.12.7.1.jar
jackson-dataformat-cbor-2.12.6.jar
jmespath-java-1.12.577.jar
joda-time-2.8.1.jar
redshift-jdbc42-2.1.0.30.jar

Connecting to Redshift with for example com.amazon.redshift.plugin.BrowserIdcAuthPlugin fails when using the Maven artifact due to aws-java-sdk-ssooidc-1.12.731.jar is missing. Connecting with the zip file works fine.

Shouldn't these contain the exact same jar files?
