We already generate core pig jar even though it's not published on Maven repo. If you run "ant clean jar", you will find two jars under the build dir:
-rw-r--r-- 1 cheolsoo cheolsoo 3411312 Feb 14 09:41 pig-0.12.0-SNAPSHOT.jar -rw-r--r-- 1 cheolsoo cheolsoo 16225627 Feb 14 09:41 pig-0.12.0-SNAPSHOT-withdependencies.jar "pig-0.12.0-SNAPSHOT.jar" contains only Pig but nothing else, whereas "pig-0.12.0-SNAPSHOT-withdependencies.jar" contains minimal dependencies. Please look at build.xml regarding what dependencies are packaged into these jar files: <fileset dir="${ivy.lib.dir}" id="runtime.dependencies-withouthadoop.jar"> <patternset id="pattern.runtime.dependencies-withouthadoop.jar"> <include name="antlr-runtime-${antlr.version}.jar"/> <include name="ST4-${stringtemplate.version}.jar"/> <include name="jline-${jline.version}.jar"/> <include name="jackson-mapper-asl-${jackson.version}.jar"/> <include name="jackson-core-asl-${jackson.version}.jar"/> <include name="joda-time-${joda-time.version}.jar"/> <include name="guava-${guava.version}.jar"/> <include name="automaton-${automaton.version}.jar"/> <include name="jansi-${jansi.version}.jar"/> </patternset> </fileset> <fileset dir="${ivy.lib.dir}" id="runtime.dependencies.jar"> <patternset id="pattern.runtime.dependencies.jar"> <patternset refid="pattern.runtime.dependencies-withouthadoop.jar"/> <include name="hadoop-core-${hadoop-core.version}.jar"/> <include name="hadoop-*-${hadoop-common.version}.jar"/> <exclude name="hadoop-hdfs-${hadoop-hdfs.version}.jar"/> <include name="junit-${junit.version}.jar"/> <include name="jsch-${jsch.version}.jar"/> <include name="protobuf-java-${protobuf-java.version}.jar"/> <include name="avro-${avro.version}.jar"/> <include name="commons*.jar"/> <include name="log4j*.jar"/> <include name="slf4j*.jar"/> <include name="jsp-api*.jar"/> </patternset> </fileset> <fileset dir="${ivy.lib.dir}" id="core.dependencies.jar"> <exclude name="**.*jar"/> </fileset> Thanks, Cheolsoo On Thu, Feb 14, 2013 at 9:32 AM, Bill Graham <billgra...@gmail.com> wrote: > How would this be different than pig-*-withdependencies.jar? > > > On Wed, Feb 13, 2013 at 9:59 PM, Prashant Kommireddi <prash1...@gmail.com > >wrote: > > > Should pig have a standalone jar?
