-------------------------------------
Summary: regenerate bug
Key: LUCENE-6102
URL: https://issues.apache.org/jira/browse/LUCENE-6102
Project: Lucene - Core
Issue Type: Bug
Components: general/build
Affects Versions: 4.10.2
Environment: PYTHON 2.6
JDK 1.7.0.45
ANT 1.9.2
Reporter: Martin Gainty
<!--attempt to run python w/o PYTHONHOME and PYTHONPATH defined causes
regenerate task to fubar and not generate .jflex file -->
<!-- fix is here -->
<target name="regenerate" >
<property name="python.exe" value="%CYGWIN_HOME%/bin/python.exe" />
<!-- target name="generate-jflex-html-char-entities" -->
<echo>Running ${python.exe} on htmlentity.py</echo>
<exec executable="cmd.exe">
<arg value="/c"/>
<arg value="pythonit.bat"/>
</exec>
<fixcrlf
file="src/java/org/apache/lucene/analysis/charfilter/HTMLCharacterEntities.jflex"
encoding="UTF-8"/>
</target>
<!--end contents of pythonit.<bat/sh> -->
<!--this will gen the Impl.java from the .jflex input -->
<target name="jflex-HTMLCharacterEntities" depends="regenerate">
<taskdef name="jflex-1.5.1" classname="JFlex.anttask.JFlexTask"
classpath="%ANT_HOME%/lib"/>
<echo>Run jflex-HTMLCharacterEntities</echo>
<!-- run-jflex-and-disable-buffer-expansion
dir="%LUCENE_HOME%/analysis/common/src/java/org/apache/lucene/analysis/standard"
name="StandardTokenizerImpl"/ -->
<property name="dir"
value="%LUCENE_HOME%/analysis/common/src/java/org/apache/lucene/analysis/standard"
/>
<property name="name" value="HTMLCharacterEntitiesImpl" />
<jflex-1.5.1
file="%LUCENE_HOME%/analysis/common/src/java/org/apache/lucene/charfilter/HTMLCharacterEntities.jflex"
outdir="%LUCENE_HOME%/analysis/common/src/java/org/apache/lucene/charfilter"
nobak="off" />
<!-- /macrodef -->
</target>
when I regen'ed HTMLCharacterEntities.jflex I wanted to use jflex to generate
the HtmlCharacterEntitiesImpl.java file the above target
jflex-HTMLCharacterEntities will gen that file for you
Nota Bene; take note of the bat/sh that properly sets PYTHONHOME and PYTHONPATH
so Python can locate subordinate .pyc components
I also had to tweak Gerwin Kleins JFlex library from 2003 to take inputFile and
outputDir parameters
Erik/Michael: does the original regenerate work for you?
