             Summary: Runtime to contain Selenium and dependencies only once
                 Key: NUTCH-2106
                 URL: https://issues.apache.org/jira/browse/NUTCH-2106
             Project: Nutch
          Issue Type: Bug
          Components: build
    Affects Versions: 1.11
            Reporter: Sebastian Nagel
             Fix For: 1.11


All Selenium-based plugins contain the same dependendent jars which significantly affects the size of runtime and bin package:
{noformat}
% du -hs runtime/local/plugins/*selenium/ runtime/deploy/*.job
25M runtime/local/plugins/lib-selenium/
25M runtime/local/plugins/protocol-interactiveselenium/
25M runtime/local/plugins/protocol-selenium/
182M runtime/deploy/apache-nutch-1.11-SNAPSHOT.job
{noformat}

Since all plugins depend on the same Selenium version we could bundle the dependencies in lib-selenium and let the other plugins load it from there:
- let lib-selenium export all dependent libs, e.g.:
{code:xml|title=lib-selenium/plugin.xml}
<runtime>
  ...
  <library name="selenium-java-2.44.0.jar">
    <export name="*"/>
  </library>
{code}
- both protocol plugins already import lib-selenium: the dependencies in ivy.xml can be removed

As expected, these changes make the runtime smaller:
{noformat}
25M runtime/local/plugins/lib-selenium/
20K runtime/local/plugins/protocol-interactiveselenium/
16K runtime/local/plugins/protocol-selenium/
138M runtime/deploy/apache-nutch-1.11-SNAPSHOT.job
{noformat}

Open points:
- I've tested only protocol-selenium using chromedriver. Should also test protocol-interactiveselenium?
- What about phantomjsdriver-1.2.1.jar? It was contained in lib-selenium and protocol-selenium but not protocol-interactiveselenium. Is there a reason for this?
