Lucene/Solr Maven build instructions
====================================
Contents:
A. How to use nightly Jenkins-built Lucene/Solr Maven artifacts
B. How to generate Lucene Maven artifacts
C. How to generate Solr Maven artifacts
D. How to use Maven to build Lucene/Solr
-----
A. How to use nightly Jenkins-built Lucene/Solr Maven artifacts
The most recently produced nightly Jenkins-built Lucene and Solr Maven
artifacts are available in Maven repository layout here:
<https://builds.apache.org/hudson/job/Lucene-Solr-Maven-trunk/lastSuccessfulBuild/artifact/maven_artifacts/>
B. How to generate Lucene Maven artifacts
1. Prerequisites: JDK 1.5+, Ant 1.7.X, and maven-ant-tasks-2.1.1.jar
In order to generate Maven artifacts for Lucene/Solr, you must first
download the Maven ant tasks JAR (maven-ant-tasks-2.1.1.jar), e.g.
from <http://maven.apache.org/ant-tasks/download.html>, and add it
to any one of the following:
a. Your $HOME/.ant/lib/ directory (C:\Users\username\.ant\lib\ under
Windows Vista/7); or
b. Your $ANT_HOME/lib/ directory (%ANT_HOME%\lib\ under Windows); or
c. Your $CLASSPATH (%CLASSPATH% under Windows); or
d. Your ant commond line: "-lib /path/to/maven-ant-tasks-2.1.1.jar".
2. Run the following command from the lucene/ directory:
ant generate-maven-artifacts
The above command will create an internal Maven repository under
lucene/dist/maven/, including POMs, binary .jars, source .jars,
and javadoc .jars, for Lucene Core, for the Lucene test framework,
for each contrib, and for each module under the top-level modules/
directory.
C. How to generate Solr Maven artifacts
1. Prerequisites: JDK 1.6+; Ant 1.7.X; and maven-ant-tasks-2.1.1.jar
(see item A.1. above for where to put the Maven ant tasks jar).
2. Run the following from the solr/ directory:
ant generate-maven-artifacts
The above command will create an internal Maven repository under
solr/package/maven/, including POMs, binary .jars, source .jars,
and javadoc .jars, for Solr Core, for the Solr test framework,
for each contrib, and for the Solr .war (for which there are no
source or javadoc .jars).
D. How to use Maven to build Lucene/Solr
In summary, to enable Maven builds, perform the following:
svn update
ant get-maven-poms
mvn -N -Pbootstrap install
The details, followed by some example Maven commands:
1. Prerequisites: JDK 1.5+ (for Lucene); JDK 1.6+ (for Solr);
Maven 2.2.1 or 3.0.X
2. Make sure your sources are up to date. If you checked your sources out
from the Apache Subversion repository, run "svn update" from the top
level.
3. Copy the Maven POM templates from under dev-tools/maven/ to where they
they need to go in order to drive the Maven build, using the following
command from the top-level directory:
ant get-maven-poms
Note that you will need to do this whenever changes to the POM
templates are committed. It's a good idea to follow every "svn update"
with "ant get-maven-poms" for this reason.
The above command copies all of the POM templates from dev-tools/maven/,
filling in the project version with the default "X.X-SNAPSHOT". If you
want the POMs and the Maven-built artifacts to have a version other than
the default, you can supply an alternate version on the command line
with the above command, e.g.:
ant -Dversion=4.0-my-special-version get-maven-poms
4. Populate your local repository with .jars & POMs for dependencies that
are not available from public Maven repositories (a.k.a. "non-mavenized
dependencies"):
mvn -N -Pbootstrap install
Note that you will need to do this whenever changes to the non-Mavenized
dependencies are committed. It's a good idea to follow every
"svn update" with "ant get-maven-poms" and "mvn -N -Pbootstrap install"
for this reason.
Some example Maven commands you can use after you perform the above
preparatory steps:
- Compile, package, and install all artifacts to your local repository:
mvn install
After compiling and packaging, but before installing each module's
artifact, the above command will also run all the module's tests.
To compile, package and install all artifacts without running any tests:
mvn -DskipTests install
- Run tests:
mvn test
To run all test methods defined in a test class:
mvn -Dtest=TestClassName test

@ -472,13 +472,63 @@ Changes in backwards compatibility policy
a method getHeapArray() was added to retrieve the internal heap array as a
non-generic Object[]. (Uwe Schindler, Yonik Seeley)
* LUCENE-1076: IndexWriter.setInfoStream now throws IOException
(Mike McCandless, Shai Erera)
* LUCENE-3084: MergePolicy.OneMerge.segments was changed from
SegmentInfos to a List<SegmentInfo>; this is actually a minor change
because SegmentInfos itself extends Vector<SegmentInfo>. (Uwe
Schindler, Mike McCandless)
Changes in runtime behavior
* LUCENE-3065: When a NumericField is retrieved from a Document loaded
from IndexReader (or IndexSearcher), it will now come back as
NumericField not as a Field with a string-ified version of the
numeric value you had indexed. Note that this only applies for
newly-indexed Documents; older indices will still return Field
with the string-ified numeric value. If you call Document.get(),
the value comes still back as String, but Document.getFieldable()
returns NumericField instances. (Uwe Schindler, Ryan McKinley,
Mike McCandless)
New features
* LUCENE-3082: Added index upgrade tool oal.index.IndexUpgrader
that allows to upgrade all segments to last recent supported index
format without fully optimizing. (Uwe Schindler, Mike McCandless)
* LUCENE-1076: Added TieredMergePolicy which is able to merge non-contiguous
segments, which means docIDs no longer necessarily stay "in order".
(Mike McCandless, Shai Erera)
* LUCENE-3071: Adding ReversePathHierarchyTokenizer, added skip parameter to
PathHierarchyTokenizer (Olivier Favre via ryan)
API Changes
* LUCENE-3061: IndexWriter's getNextMerge() and merge(OneMerge) are now public
(though @lucene.experimental), allowing for custom MergeScheduler
implementations. (Shai Erera)
* LUCENE-3065: Document.getField() was deprecated, as it throws
ClassCastException when loading lazy fields or NumericFields.
(Uwe Schindler, Ryan McKinley, Mike McCandless)
Optimizations
* LUCENE-2990: ArrayUtil/CollectionUtil.*Sort() methods now exit early
on empty or one-element lists/arrays. (Uwe Schindler)
* LUCENE-2897: Apply deleted terms while flushing a segment. We still
buffer deleted terms to later apply to past segments. (Mike McCandless)
Bug fixes
* LUCENE-2996: addIndexes(IndexReader) did not flush before adding the new
indexes, causing existing deletions to be applied on the incoming indexes as
well. (Shai Erera, Mike McCandless)
* LUCENE-3024: Index with more than 2.1B terms was hitting AIOOBE when
seeking TermEnum (eg used by Solr's faceting) (Tom Burton-West, Mike
McCandless)
@ -491,6 +541,17 @@ Bug fixes
very special use cases of the TokenStream-API, most users would not
have recognized it. (Uwe Schindler, Robert Muir)
* LUCENE-3054: PhraseQuery can in some cases stack overflow in
SorterTemplate.quickSort(). This fix also adds an optimization to
PhraseQuery as term with lower doc freq will also have less positions.
(Uwe Schindler, Robert Muir, Otis Gospodnetic)
Test Cases
* LUCENE-3002: added 'tests.iter.min' to control 'tests.iter' by allowing to
stop iterating if at least 'tests.iter.min' ran and a failure occured.
(Shai Erera, Chris Hostetter)

that warming is free to do whatever it needs to. (Earwin Burrfoot
via Mike McCandless)
* LUCENE-3029: Fix corner case when MultiPhraseQuery is used with zero
position-increment tokens that would sometimes assign different
scores to identical docs. (Mike McCandless)
* LUCENE-2486: Fixed intermittent FileNotFoundException on doc store
files when a mergedSegmentWarmer is set on IndexWriter. (Mike
McCandless)

* This is an easy-to-use tool that upgrades all segments of an index from previous Lucene versions
* to the current segment file format. It can be used from command line:
* <pre>
* java -cp lucene-core.jar org.apache.lucene.index.IndexUpgrader [-delete-prior-commits] [-verbose] indexDir
* </pre>
* Alternatively this class can be instantiated and {@link #upgrade} invoked. It uses {@link UpgradeIndexMergePolicy}
* and triggers the upgrade via an optimize request to {@link IndexWriter}.
* <p>This tool keeps only the last commit in an index; for this
* reason, if the incoming index has more than one commit, the tool
* refuses to run by default. Specify {@code -delete-prior-commits}
* to override this, allowing the tool to delete all but the last commit.
* From Java code this can be enabled by passing {@code true} to
* {@link #IndexUpgrader(Directory,PrintStream,boolean)}.
