| Building Arrow Java |
| =================== |
| |
| .. contents:: |
| |
| System Setup |
| ============ |
| |
| Arrow Java uses the `Maven <https://maven.apache.org/>`_ build system. |
| |
| Building requires: |
| |
| * JDK 8, 9, 10, 11, 17, or 18, but only JDK 8, 11 and 17 are tested in CI. |
| * Maven 3+ |
| |
| Building |
| ======== |
| |
| All the instructions below assume that you have cloned the Arrow git |
| repository: |
| |
| .. code-block:: |
| |
| $ git clone https://github.com/apache/arrow.git |
| $ cd arrow |
| $ git submodule update --init --recursive |
| |
| These are the options available to compile Arrow Java modules with: |
| |
| * Maven build tool. |
| * Docker Compose. |
| * Archery. |
| |
| Building Java Modules |
| --------------------- |
| |
| To build the default modules, go to the project root and execute: |
| |
| Maven |
| ~~~~~ |
| |
| .. code-block:: |
| |
| $ cd arrow/java |
| $ export JAVA_HOME=<absolute path to your java home> |
| $ java --version |
| $ mvn clean install |
| |
| Docker compose |
| ~~~~~~~~~~~~~~ |
| |
| .. code-block:: |
| |
| $ cd arrow/java |
| $ export JAVA_HOME=<absolute path to your java home> |
| $ java --version |
| $ docker-compose run debian-java |
| |
| Archery |
| ~~~~~~~ |
| |
| .. code-block:: |
| |
| $ cd arrow/java |
| $ export JAVA_HOME=<absolute path to your java home> |
| $ java --version |
| $ archery docker run debian-java |
| |
| Building JNI Libraries (\*.dylib / \*.so / \*.dll) |
| -------------------------------------------------- |
| |
| First, we need to build the `C++ shared libraries`_ that the JNI bindings will use. |
| We can build these manually or we can use `Archery`_ to build them using a Docker container |
| (This will require installing Docker, Docker Compose, and Archery). |
| |
| .. note:: |
| If you are building on Apple Silicon, be sure to use a JDK version that was compiled |
| for that architecture. See, for example, the `Azul JDK <https://www.azul.com/downloads/?os=macos&architecture=arm-64-bit&package=jdk>`_. |
| |
| If you are building on Windows OS, see :ref:`Developing on Windows <developers-cpp-windows>`. |

| Building Java JNI Modules |
| ------------------------- |
| |
| - To compile the JNI bindings, use the ``arrow-c-data`` Maven profile: |
| |
| .. code-block:: |
| |
| $ cd arrow/java |
| $ mvn -Darrow.c.jni.dist.dir=<absolute path to your arrow folder>/java-dist/lib -Parrow-c-data clean install |
| |
| - To compile the JNI bindings for ORC / Gandiva / Dataset, use the ``arrow-jni`` Maven profile: |
| |
| .. code-block:: |
| |
| $ cd arrow/java |
| $ mvn \ |
| -Darrow.cpp.build.dir=<absolute path to your arrow folder>/java-dist/lib/ \ |
| -Darrow.c.jni.dist.dir=<absolute path to your arrow folder>/java-dist/lib/ \ |
| -Parrow-jni clean install |
| |
| IDE Configuration |
| ================= |
| |
| IntelliJ |
| -------- |
| |
| To start working on Arrow in IntelliJ: build the project once from the command |
| line using ``mvn clean install``. Then open the ``java/`` subdirectory of the |
| Arrow repository, and update the following settings: |
| |
| * In the Files tool window, find the path ``vector/target/generated-sources``, |
| right click the directory, and select Mark Directory as > Generated Sources |
| Root. There is no need to mark other generated sources directories, as only |
| the ``vector`` module generates sources. |
| * For JDK 8, disable the ``error-prone`` profile to build the project successfully. |
| * For JDK 11, due to an `IntelliJ bug |
| <https://youtrack.jetbrains.com/issue/IDEA-201168>`__, you must go into |
| Settings > Build, Execution, Deployment > Compiler > Java Compiler and disable |
| "Use '--release' option for cross-compilation (Java 9 and later)". Otherwise |
| you will get an error like "package sun.misc does not exist". |
| * You may want to disable error-prone entirely if it gives spurious |
| warnings (disable both error-prone profiles in the Maven tool window |
| and "Reload All Maven Projects"). |
| * If using IntelliJ's Maven integration to build, you may need to change |
| ``<fork>`` to ``false`` in the pom.xml files due to an `IntelliJ bug |
| <https://youtrack.jetbrains.com/issue/IDEA-278903>`__. |
| |
| You may not need to update all of these settings if you build/test with the |
| IntelliJ Maven integration instead of with IntelliJ directly. |
| |
| Common Errors |
| ============= |
| |
| * When working with the JNI code: if the C++ build cannot find dependencies, with errors like these: |
| |
| .. code-block:: |
| |
| Could NOT find Boost (missing: Boost_INCLUDE_DIR system filesystem) |
| Could NOT find Lz4 (missing: LZ4_LIB) |
| Could NOT find zstd (missing: ZSTD_LIB) |
| |
| Specify that the dependencies should be downloaded at build time (more details at `Dependency Resolution`_): |
| |
| .. code-block:: |
| |
| -Dre2_SOURCE=BUNDLED \ |
| -DBoost_SOURCE=BUNDLED \ |
| -Dutf8proc_SOURCE=BUNDLED \ |
| -DSnappy_SOURCE=BUNDLED \ |
| -DORC_SOURCE=BUNDLED \ |
| -DZLIB_SOURCE=BUNDLED |

| |
| |
| Installing Nightly Packages |
| =========================== |
| |
| .. warning:: |
| These packages are not official releases. Use them at your own risk. |
| |
| Arrow nightly builds are posted on the mailing list at `builds@arrow.apache.org`_. |
| The artifacts are uploaded to GitHub. For example, for 2022/07/30, they can be found at `Github Nightly`_. |
| |
| |
| Installing from Apache Nightlies |
| -------------------------------- |
| 1. Look up the nightly version number for the Arrow libraries used. |
| |
| For example, for ``arrow-memory``, visit https://nightlies.apache.org/arrow/java/org/apache/arrow/arrow-memory/ and see what versions are available (e.g. 9.0.0.dev501). |
| 2. Add Apache Nightlies Repository to the Maven/Gradle project. |
| |
| .. code-block:: xml |
| |
| <properties> |
| <arrow.version>9.0.0.dev501</arrow.version> |
| </properties> |
| ... |
| <repositories> |
| <repository> |
| <id>arrow-apache-nightlies</id> |
| <url>https://nightlies.apache.org/arrow/java</url> |
| </repository> |
| </repositories> |
| ... |
| <dependencies> |
| <dependency> |
| <groupId>org.apache.arrow</groupId> |
| <artifactId>arrow-vector</artifactId> |
| <version>${arrow.version}</version> |
| </dependency> |
| </dependencies> |
| ... |
| |
| Installing Manually |
| ------------------- |
| |
| 1. Decide nightly packages repository to use, for example: https://github.com/ursacomputing/crossbow/releases/tag/nightly-packaging-2022-07-30-0-github-java-jars |
| 2. Add packages to your pom.xml, for example: flight-core (it depends on: arrow-format, arrow-vector, arrow-memeory-core and arrow-memory-netty). |
| |
| .. code-block:: xml |
| |
| <properties> |
| <maven.compiler.source>8</maven.compiler.source> |
| <maven.compiler.target>8</maven.compiler.target> |
| <arrow.version>9.0.0.dev501</arrow.version> |
| </properties> |
| |
| <dependencies> |
| <dependency> |
| <groupId>org.apache.arrow</groupId> |
| <artifactId>flight-core</artifactId> |
| <version>${arrow.version}</version> |
| </dependency> |
| </dependencies> |
| |
| 3. Download the necessary pom and jar files to a temporary directory: |
| |
| .. code-block:: shell |
| |
| $ mkdir nightly-packaging-2022-07-30-0-github-java-jars |
| $ cd nightly-packaging-2022-07-30-0-github-java-jars |
