the "missing javadocs" checker needed tweaks to work with the format changes of java 13. As a followup we may investigate javadoc (maybe the new doclet api). It has its own missing checks too now, but they are black vs white (either fully documented or not checked), whereas this python tool allows us to "improve", e.g. enforce that all classes have doc, even if all methods do not yet. |

Apache Lucene and Solr
Apache Lucene is a high-performance, full featured text search engine library written in Java.
Apache Solr is an enterprise search platform written using Apache Lucene. Major features include full-text search, index replication and sharding, and result faceting and highlighting.
Online Documentation
This README file only contains basic setup instructions. For more comprehensive documentation, visit:
Building Lucene/Solr
(You do not need to do this if you downloaded a pre-built package)
Building with Ant
Lucene and Solr are built using Apache Ant. To build Lucene and Solr, run:
ant compile
If you see an error about Ivy missing while invoking Ant (e.g., .ant/lib does not exist
), run ant ivy-bootstrap
and retry.
Sometimes you may face issues with Ivy (e.g., an incompletely downloaded artifact). Cleaning up the Ivy cache and retrying is a workaround for most of such issues:
rm -rf ~/.ivy2/cache
The Solr server can then be packaged and prepared for startup by running the
following command from the solr/
directory:
ant server
Building with Gradle
There is ongoing work (see LUCENE-9077) to switch the legacy ant-based build system to gradle. Please give it a try!
At the moment of writing, the gradle build requires precisely Java 11 (it may or may not work with newer Java versions).
To build Lucene and Solr, run (./
can be omitted on Windows):
./gradlew assemble
The command above also packages a full distribution of Solr server; the package can be located at:
solr/packaging/build/solr-*
Note that the gradle build does not create or copy binaries throughout the source repository (like ant build does) so you need to switch to the packaging output folder above; the rest of the instructions below remain identical.
Running Solr
After building Solr, the server can be started using
the bin/solr
control scripts. Solr can be run in either standalone or
distributed (SolrCloud mode).
To run Solr in standalone mode, run the following command from the solr/
directory:
bin/solr start
To run Solr in SolrCloud mode, run the following command from the solr/
directory:
bin/solr start -c
The bin/solr
control script allows heavy modification of the started Solr.
Common options are described in some detail in solr/README.txt. For an
exhaustive treatment of options, run bin/solr start -h
from the solr/
directory.
Development/IDEs
Ant can be used to generate project files compatible with most common IDEs. Run the ant command corresponding to your IDE of choice before attempting to import Lucene/Solr.
- Eclipse -
ant eclipse
(See this for details) - IntelliJ -
ant idea
(See this for details) - Netbeans -
ant netbeans
(See this for details)
Gradle build and IDE support
- IntelliJ - IntelliJ idea can import the project out of the box. Code formatting conventions should be manually adjusted.
- Eclipse - Not tested.
- Netbeans - Not tested.
Running Tests
The standard test suite can be run with the command:
ant test
Like Solr itself, the test-running can be customized or tailored in a number or ways. For an exhaustive discussion of the options available, run:
ant test-help
Gradle build and tests
Run the following command to display an extensive help for running tests with gradle:
./gradlew helpTests
