[jira] [Resolved] (KYLIN-3481) Kylin Jdbc: Shaded dependencies
should not be transitive

Shaofeng SHI resolved KYLIN-3481.
---------------------------------
Resolution: Fixed
> Kylin Jdbc: Shaded dependencies should not be transitive
> --------------------------------------------------------
>
> Key: KYLIN-3481
> URL: https://issues.apache.org/jira/browse/KYLIN-3481
> Project: Kylin
> Issue Type: Improvement
> Components: Driver - JDBC
> Affects Versions: v2.4.0
> Reporter: Ian Hu
> Assignee: Ian Hu
> Priority: Minor
> Fix For: v2.5.0
>
>
> kylin-jdbc use dependencies as shaded, so they should not be transitive.
> As far as I known, SHADE a dependency to avoid dependency conflict, but at v2.4.0, the dependencies in kylin-jdbc are default compile scope and are transitive resolved, that may cause some dependency conflicts.
> We should mark shaded dependencies as optional
>
> There are two solutions about the fixation:
> # mark dependency as `optional`
> # or change the dependency scope to provided, and add shade artifactSets with include
> {code:java}
> <dependency>
> <groupId>org.apache.httpcomponents</groupId>
> <artifactId>httpclient</artifactId>
> <optional>true</optional> // add this
> </dependency>
> // ============= or =============
> <dependency>
> <groupId>org.apache.httpcomponents</groupId>
> <artifactId>httpclient</artifactId>
> <scope>provided</scope>
> </dependency>
> // and
> <artifactSet>
> <excludes>
> <exclude>org.slf4j:jcl-over-slf4j:*</exclude>
> </excludes>
> <includes>
> <include>org.apache.httpcomponents:httpclient:*</include> // force include provided scope
> <include>org.apache.calcite.avatica:avatica-core:*</include> // force include provided scope
> </includes>
> </artifactSet>{code}
