Do you get the exception if you run ant before changing the data files?
"Header authentication failed, please check if you have a valid ICU data file"
Check with the ICU project as to the proper format for THEIR files. I mean, this doesn't sound like a Lucene issue.
Maybe it could be as simple as whether the data file should have DOS or UNIX or Mac line endings (CRLF vs. NL vs. CR.) Be sure to use an editor that satisfies the requirements of ICU.
To be clear, Lucene itself does not have a published API for modifying the mappings of ICU.

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. --------------------------------------------------------------------- To unsubscribe, e-mail: java-user-unsubscr...@lucene.apache.org For additional commands, e-mail: java-user-h...@lucene.apache.org
