## Development Info
### Dependencies
XOWA has seven dependencies:

* JUnit 4.8.2 (default version with Eclipse)
* [SWT 4.5.1](http://download.eclipse.org/eclipse/downloads/drops4/R-4.5-201506032000/)
* [LuaJ](https://github.com/gnosygnu/luaj_xowa)
* [JTidy](https://github.com/gnosygnu/jtidy_xowa jtidy_xowa.jar)
* [SQLite JDBC](https://bitbucket.org/xerial/sqlite-jdbc/downloads)
* [MySQL JDBC](https://dev.mysql.com/downloads/connector/j/)
* [Postgres JDBC](https://jdbc.postgresql.org/download.html)

### Compilation instructions (ANT command-line)
#### Setup the XOWA app
* Download the latest XOWA app package for your operating system. For example, if you're on a 64-bit Linux system, "xowa_app_linux_64_v1.9.5.1.zip".
* Unzip the XOWA app package to a directory. For the sake of simplicity, these instructions assume this directory is "/xowa/"
* Review your directories. You should have the following:
    * An XOWA jar: "/xowa/xowa_linux_64.jar"
    * An XOWA "/bin/any/" directory with several jar files. For example, "/xowa/bin/any/java/apache/commons-compress-1.5.jar"
    * An XOWA "/bin/linux_64/" directory with an SWT jar: "/xowa/bin/linux_64/swt/swt.jar"

#### Setup the XOWA source
* Download the latest XOWA source archive. For example: "xowa_source_v1.9.5.1.7z"
* Unzip the source to "/xowa/dev". When you're done, you'll have a file called "/xowa/dev/build.xml" as well as others
    * NOTE: if you're not on a Linux 64-bit system, overwrite the swt jar at "/xowa/dev/150_gfui/lib/swt.jar" with the copy from your "/bin/OS" directory. For example, if you're on a 64 bit Windows system, replace "/xowa/dev/150_gfui/lib/swt.jar" with "/bin/windows_64/swt/swt.jar"

#### Run the ant file
* Open up a console, and run "ant -buildfile build.xml -Dplat_name=linux_64"

### IDE instructions (Eclipse)
