To build my code in Java 5, it's required to upgrade JavaCC to
version 4.0. I have downloaded JavaCC source and built the
JavaCC.zip file.
I'm having problem when executing javacc from ant build.xml file. ant
is looking for "COM.sun.labs..." when the source that I have built
contains "org.javacc" package name. "COM.sun.labs" is defined in the
COM_PACKAGE value in the
C:\Apache-Ant-1.6.5\apache-ant-1.6.5\docs\manual\api\constant-
values.html#org.apache.tools.ant.taskdefs.optional.javacc.JavaCC.COM_P
ACKAGE.
There is also an ORG_PACKAGE_3_1 defined as "org.javacc".
My questions are:
1. How do I change my build environment so ant will resolve to the
"org.javacc" package? OR
2. How do I change the COM_PACKAGE Constant Field Value in ant so I
will resolve with "org.javacc" instead of "COM.sun.labs"?
Are you using the latest version of Ant? I don't recall the
specifics, but in Lucene we used to use <java> to launch the JavaCC
program, but I switched it back to <javacc> and all has been well
with JavaCC 3.2. I have not tried 4.0 though. We define a macro to
launch JavaCC - see http://svn.apache.org/repos/asf/lucene/java/trunk/
common-build.xml - like this:
<macrodef name="invoke-javacc">
<attribute name="target"/>
<attribute name="outputDir"/>
<sequential>
<mkdir dir="@{outputDir}"/>
<javacc
target="@{target}"
outputDirectory="@{outputDir}"
debugTokenManager="${javacc.debug.tokenmgr}"
debugParser="${javacc.debug.parser}"
debuglookahead="${javacc.debug.lookahead}"
javacchome="${javacc.home}"
/>
</sequential>
</macrodef>
Maybe <javacc> cannot work with JavaCC 4.0 though - its a bit brittle
under the covers in this regard, last time I looked.
