Hello, I try to use lucene-icu li in solr-4.6.1. I need to change a char mapping in lucene-icu. I have made changes to
lucene/analysis/icu/src/data/utr30/DiacriticFolding.txt and built jar file using ant , but it did not help. I took a look to lucene/analysis/icu/build.xml and see these lines <property name="gennorm2.src.files" value="nfc.txt nfkc.txt nfkc_cf.txt BasicFoldings.txt DiacriticFolding.txt DingbatFolding.txt HanRadicalFolding.txt NativeDigitFolding.txt"/> <property name="gennorm2.tmp" value="${build.dir}/gennorm2/utr30.tmp"/> <property name="gennorm2.dst" value="${resources.dir}/org/apache/lucene/analysis/icu/utr30.nrm"/> <target name="gennorm2" depends="gen-utr30-data-files"> <echo>Note that the gennorm2 and icupkg tools must be on your PATH. These tools are part of the ICU4C package. See http://site.icu-project.org/ </echo> <mkdir dir="${build.dir}/gennorm2"/> <exec executable="gennorm2" failonerror="true"> <arg value="-v"/> <arg value="-s"/> <arg value="${utr30.data.dir}"/> <arg line="${gennorm2.src.files}"/> <arg value="-o"/> <arg value="${gennorm2.tmp}"/> </exec> <!-- now convert binary file to big-endian --> <exec executable="icupkg" failonerror="true"> <arg value="-tb"/> <arg value="${gennorm2.tmp}"/> <arg value="${gennorm2.dst}"/> </exec> <delete file="${gennorm2.tmp}"/> </target> looks like ant does not execute gennorm2. If I build utr30.nrm file using gennorm2 manually and replacing utr30.nrm in the jar file then starting solr gives the following error. Caused by: java.lang.RuntimeException: java.io.IOException: ICU data file error: Header authentication failed, please check if you have a valid ICU data file My questions are; 1. if the above code in the build file does not get executed then how the utr30 file is generated? 2. How to change a character mapping. Thanks. Alex.
