Karl Wright commented on CONNECTORS-1458:
-----------------------------------------

After making the obvious changes, we've still got a problem when running the HSQLDB IT tests:

I don't know why Zookeeper is not being picked up here; while it exists at the root level,
the test itself may need to explicitly reference it.  Looking into that next...

>                 URL: https://issues.apache.org/jira/browse/CONNECTORS-1458
>             Project: ManifoldCF
>          Issue Type: Task
>          Components: Lucene/SOLR connector
>    Affects Versions: ManifoldCF 2.8.1
>            Reporter: Karl Wright
>            Assignee: Karl Wright
>             Fix For: ManifoldCF 2.9

> We need to bring our SolrJ dependency up to date, since SolrJ 7.0.0 was just released.
> I did some preliminary dependency analysis using mvn dependency:tree and found that the
following required dependencies are present:
> {code}
> [INFO] +- org.apache.solr:solr-solrj:jar:7.0.0:compile
> [INFO] |  +- org.apache.commons:commons-math3:jar:3.4.1:compile
> [INFO] |  +- org.codehaus.woodstox:stax2-api:jar:3.1.4:compile
> [INFO] |  +- org.codehaus.woodstox:woodstox-core-asl:jar:4.4.1:compile
> [INFO] |  \- org.slf4j:jcl-over-slf4j:jar:1.7.7:compile
> {code}
> There is, however, no explicit dependency on httpcomponents/httpclient anymore, so I
realized I'd better look at the optional dependencies, as listed here:
> https://mvnrepository.com/artifact/org.apache.solr/solr-solrj/7.0.0
> These include:
> httpcomponents/httpclient 4.4.1 (we're at 4.5.3 so we're good there)
> zookeeper 3.4.10 (need to update)
> woodstox-core-asl  4.4.1 (need to update)
> noggit 0.8 (need to update)
> slf4j-api 1.7.7 (need to update)
