presto-jdbc-java6

Presto JDBC driver compatible with Java 6

Motivation

Many companies are still using Java 6 VM's for for old systems. The purpose of this project to allow such companies to connect to Presto database through JDBC. This cannot be done using official Presto JDBC driver as it requires Java 8 VM.

Building

Setup JDK 6 toolchain

Build script is mvn based and depends on toolchains feature of Maven.

We need that as new version of maven require JRE 7 to run itself. And we want to compile project with JDK 6.

To configure Java 6 toolchain in ~/.m2/toolchains.xml put

<?xml version="1.0" encoding="UTF8"?>
<toolchains>
    <!-- JDK toolchains -->
    <toolchain>
        <type>jdk</type>
        <provides>
            <version>1.6</version>
            <vendor>sun</vendor>
        </provides>
        <configuration>
          <jdkHome>/Library/Java/JavaVirtualMachines/1.6.0.jdk/Contents/Home/</jdkHome>
        </configuration>
    </toolchain>
</toolchains>

Replace contents of jdkHome with path matching your machine.

Build

To build without tests execute:

mvn install -DskipTests=true  

Tests

To run integration tests you need to explicitly specify path to JDK 8, which will be used to spawn mock Presto instance.

Run tests with command:

 mvn test -Djava8.home=/usr/lib/jvm/java-8-oracle

Replace value of java8.home property with path valid on your system.

Artifacts

Build produces single library artifact presto-jdbc-java6-<version>.jar. Artifact does not depend on any external libraries.

After build, library will be available in ~/.m2/repository/com/facebook/presto/presto-jdbc-java6.

Currently we do not publish artifacts from this project to central maven repository.
