This repo shows how to successfully build and run Lucene versions from v1.9 to v2.9.4 and all the way to v3.4. The purpose of this repo is to let myself get hands dirty and to be able to actually run old code to gain a good sense in Lucene source code.
Although I fail to build earlier versions before v1.9, I find it helpful (with the help of gitk) to study Lucene source code by walking through history. The earliest point I suggest to start reading is the first time Doug Cutting shows up in commit history (b08e28c3838e7bcab1a198e2f6d0cef687ee50e3).
- Clone lucene-solr:
$ git clone https://gitee.com/t-k-/lucene-solr.git
$ export LUCENE_SRC=`pwd/lucene-solr`
$ (cd $LUCENE_SRC && git co releases/lucene/1.9)- Download an old Ant distribution:
$ cd $LUCENE_SRC
$ wget https://archive.apache.org/dist/ant/binaries/apache-ant-1.8.4-bin.tar.bz2
$ tar -xzf apache-ant-1.8.4-bin.tar.gz- Pull and run in an old JDK environment: The earliest jdk environment I can find ...
$ docker pull maven:3-jdk-6
$ docker run -it \
-v $LUCENE_SRC:/lucene \
-e JAVA_HOME=/usr/lib/jvm/java-1.6.0-openjdk-amd64 \
-e ANT_HOME=/lucene/apache-ant-1.8.4 \
maven:3-jdk-6 bash- Build and run Lucene demo In Docker environment,
$ export PATH=$PATH:${ANT_HOME}/bin
$ cd /lucene
$ rm -rf build index
$ ant jar-core jar-demo
$ export CLASSPATH=`pwd`/build
$ (cd $CLASSPATH && find -name '*.jar' -exec jar -xf {} \;)Now, let's run the Lucene demo
$ java org.apache.lucene.demo.IndexFiles ./src/java/
$ java org.apache.lucene.demo.SearchFiles$ sudo docker build -t study-lucene .
$ sudo docker run -it study-lucene java org.apache.lucene.demo.SearchFilesYou may want to attach live source code and build in container:
$ sudo docker run -it -v `pwd`/src/lucene-solr:/code/lucene study-lucene bashIndex a large corpus from container?
$ sudo docker run -it -v /home/tk/nvme0n1/corpus:/corpus study-lucene java org.apache.lucene.demo.IndexFiles /corpus
