It is not possible to emerge dev-java/lucene-2.4.0 if the system uses a Java compiler which is not javac from Sun. Snippet from the log file: common.compile-core: [mkdir] Created dir: /var/tmp/portage/dev-java/lucene-2.4.0/work/lucene-2.4.0/build/classes/java [javac] Compiling 330 source files to /var/tmp/portage/dev-java/lucene-2.4.0/work/lucene-2.4.0/build/classes/java [javac] Unrecognized option : 10000000 BUILD FAILED /var/tmp/portage/dev-java/lucene-2.4.0/work/lucene-2.4.0/common-build.xml:183: The following error occurred while executing this line: /var/tmp/portage/dev-java/lucene-2.4.0/work/lucene-2.4.0/common-build.xml:409: Compile failed; see the compiler error output for details. On my system, this happened as preferences are set to use ecj for compilation: $ cat /etc/java-config-2/build/compilers.conf COMPILERS="ecj-3.4 jikes javac" Cause: In common-build.xml: <compilerarg line="-Xmaxwarns 10000000" ></compilerarg> <compilerarg line="-Xmaxerrs 10000000" ></compilerarg> ecj-3.4 does not know that some of the -X options take parameters (in fact, no compiler can know that, but only apply a heuristic or the Sun javac should be fixed to use ‘-Xfoo=bar’ instead of ‘-Xfoo bar’.) Suggested fix: Remove the parameters from common-build.xml if a Java compiler which is not Sun javac is used.
lucene-2.4 builds perfectly with the IBM JDK, v1.4 thru 1.6 tested. Can you please show me your -X output for ecj and jikes?
Reproduced with ecj-3.4 as compiler.

I'd still like the -X output for ecj...

Usage: <options> <source files | directories> If directories are specified, then their source contents are compiled. Possible options are listed below. Options enabled by default are prefixed with '+'. Classpath options: -cp -classpath <directories and ZIP archives separated by :> specify location for application classes and sources. Each directory or file can specify access rules for types between '[' and ']' (e.g. [-X] to forbid access to type X, [~X] to discourage access to type X, [+p/X:-p/*] to forbid access to all types in package p but allow access to p/X) -bootclasspath <directories and ZIP archives separated by :> specify location for system classes. Each directory or file can specify access rules for types between '[' and ']' -sourcepath <directories and ZIP archives separated by :> specify location for application sources. Each directory or file can specify access rules for types between '[' and ']'. Each directory can further specify a specific destination directory using a '-d' option between '[' and ']'; this overrides the general '-d' option. .class files created from source files contained in a jar file are put in the user.dir folder in case no general '-d' option is specified. ZIP archives cannot override the general '-d' option -extdirs <directories separated by :> specify location for extension ZIP archives -endorseddirs <directories separated by :> specify location for endorsed ZIP archives -d <dir> destination directory (if omitted, no directory is created); this option can be overridden per source directory -d none generate no .class files -encoding <enc> specify custom encoding for all sources.

Created attachment 194739 [details, diff] use sed to take out -Xmax compiler options in common-build.xml so ecj can be used tested and works.. cheers
Confirmed, it now builds fine with ecj-3.4. Thanks! :-) This should go into the main portage tree.
InCVS.
