Subject [jira] [Commented] (LUCENE-4415) need to document/fix/remove build.xml dependencies on javascript
Date Sat, 22 Sep 2012 10:59:07 GMT


Uwe Schindler commented on LUCENE-4415:

My -1 was related to the patch! The patch is not good, as it replaces the official Java 6
javax.scripting framework by the "outdated" BSF framework, which is a completely different
implementation made for Java 4+. This patch would only work with ANT, but not JavaScript.
I would agree to add the download of rhino.jar and the above script-js.jar from the Oracle
website ( into the bootstrap path,
nothing more. Just to repat: I AM AGAINST ADDING OUTDATED BSF!

I agree that the Spec does not mandate to add "Javascript", but there *must* be one scripting
implementation. In fact the rmuir private JDK is stupid, as a large number of projects would
no longer work and this is also the reason for *every-except-FreeBSD* JDK out there to ship
with JavaScript.

The bug is on the FreeBSD side - I will check their bugtracker and suggest to use partially
IcedTea build (they already use patches from IcedTea).

By the way: I can also build a "private" thetaphi-JDK without the XERCES and XALAN XML components.
It would also be correct according to the spec, but then 90% of all Java projects would no
longer work. The critical mass of Javascript requiring projects is just not as big to see
the impact in FreeBSD.

> Radim Kolar pointed out on the solr-user mailing list that he was unable to build Solr
on his FreeBSD machine due to the use of {{<script language="javascript"... />}} tags
in the ant build file, and the lack of javascript by default in his Java install.  There was
no clear indication that he should need anything else.
> It seems like prior to releasing 4.0, we should do one of the following:
> 1) find a way to remove the dependency on using javascript in the build.xml files (ie:
our own custom ant target written in java?)
> 2) use ivy to ensure we have the rhino jar in a classpath we pass to {{<script>}}
tag (it appears we already do something similar for pegdown)
> 3) update lucene/BUILD.txt and solr/README.txt to make it clear that the rhino js.jar
is a build requirement (and link to a wiki somewhere that provides tips on how to install
it in ant if your JVM doesn't include it)
> (Assigning to Uwe in hopes that he has some inspiration, i know he's familiar with this
scripting deficiency on FreeBSD)
