Joseph Barefoot created DRILL-3589:
--------------------------------------
Summary: JDBC driver maven artifact includes a lot of unnecessary
dependencies
Key: DRILL-3589
URL: https://issues.apache.org/jira/browse/DRILL-3589
Project: Apache Drill
Issue Type: Improvement
Components: Client - JDBC
Reporter: Joseph Barefoot
Assignee: Daniel Barclay (Drill)
Priority: Minor
The Drill JDBC POM file pulls in so many unused transitive dependencies that it
takes quite a while to exclude all the unnecessary ones when using it from
within a Java project. This is similar to DRILL-3581 in that you can work
around it via exclusions of transitive dependencies, but since it makes
interoperability with other open-source projects problematic, this will keep
coming up for anyone using the JDBC driver from within any serious java app.
Considering the pom:
http://repo1.maven.org/maven2/org/apache/drill/exec/drill-jdbc/1.1.0/drill-jdbc-1.1.0.pom
...it seems that most of the unused dependencies are transitive from
drill-common and perhaps also drill-java-exec. Here's an example of some
dependencies that the JDBC driver shouldn't need (and we excluded in our
project):
parquet-*
jetty-server
javassist
commons-daemon
hibernate-validator
xalan
xercesImpl
For the record we are now able to use the JDBC driver fine from within our
project, but it did take some dependency tree analysis (and a little
trial-and-error) to figure out what to exclude. We would like to save future
developers that time.
