How to build Xerial's sqlite JDBC driver on Alpine Linux

These are the steps I took to build the sqlite JDBC driver so that it works on a musl-based Linux distro, namely Alpine Linux.

1. Install a couple of dependencies:

   # apk update && apk upgrade
   # apk add git gcc make openjdk8 maven
   # apk add perl curl unzip bash musl-dev

2. Set up JAVA_HOME:

   # export JAVA_HOME=/usr/lib/jvm/java-1.8-openjdk

3. Clone sqlite-jdbc repository:

   # git clone https://github.com/xerial/sqlite-jdbc.git

4. Build the shared object library and the JNI bindings:

   # cd sqlite-jdbc
   # make jni-header native

5. Build the JAR (some tests don't pass, you have to skip them):

   # mvn -Dmaven.test.skip=true package

6. The jar that is produced is in the target directory:

   # ls target/sqlite-jdbc*
   target/sqlite-jdbc-3.16.2-SNAPSHOT.jar

7. To use it in a gradle build, mkdir a lib directory in your gradle project, copy into it the jar that was built as above and add the following compile line to build.gradle:

   compile fileTree(dir: 'lib', include: '**/*.jar')
