     [ https://issues.apache.org/jira/browse/HBASE-18723?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

stack reopened HBASE-18723:
---------------------------

Reopen. HBASE-18674 still fails. This time it can't find the JspC that is used internally by ant task. We purge JspC transitive includes from hadoop everywhere

Poking around, a pretty recent bundling of JspC is in glassfish. It is what jetty suggests on this page: 

http://www.eclipse.org/jetty/documentation/9.4.x/jetty-jspc-maven-plugin.html

Our ant hackery doing precompile needs modernizing. I tried updating it but the mapping is not clean so leaving it as is for now.

Here is the error I get from HBASE-18674. I cannot reproduce this stuff locally though I try running the yetus commands locally (maybe if I redo the whole yetus build...)

    [mkdir] Created dir: /testptch/hbase/hbase-rest/target/hbase-webapps

>
> Do a pass over our poms. They are sloppy including unused jars and not listing actually used dependencies. Undo 'required' dependencies like junit and mockito; not all modules need these anymore.
> This cleanup motivated by failures up on jenkins where a build step is not finding transitive includes; explicit mention is needed (See failures in HBASE-18674).
