Doug,
As you can see for rtf I need to do more than just download the jar
file as there is not a precompiled version on the net. I have to
download the source and then run a number of steps to get to the
resulting jar. I'm not sure that the plugin's build.xml is the place to
be doing this as it seems to be called twice. Anyway this is just a
first cut to see what you and the rest of the list think we should do in
this situation. Unit tests won't pass as they are dependant on the file
protocol which is dependant on activation...
--- build.properties
javacc.home=/usr/java/javacc
--- build.xml
<project name="parse-rtf" default="jar">
<import file="../build-plugin.xml"/>
<mkdir dir="tmp"/>
<get src="http://www.cobase.cs.ucla.edu/pub/javacc/rtf_parser_src.jar";
dest="tmp/rtf_parser_src.jar"/>
<unjar src="tmp/rtf_parser_src.jar"
dest="tmp"/>
<javacc target="tmp/rtf/RTFParser.jj"
javacchome="${javacc.home}">
</javacc>
<mkdir dir="tmp/classes"/>
<javac srcdir="tmp" destdir="tmp/classes"/>
<jar destfile="lib/rtf-parser.jar" basedir="tmp/classes"/>
<!-- for junit test -->
<mkdir dir="${build.test}/data"/>
<copy file="sample/test.rtf" todir="${build.test}/data"/>
</project>
