    <artifactId>tess4j</artifactId>
    <version>3.0.0</version>
</dependency>

Linux Dependency

Tesseract and Ghostscript native libraries are necessary in order for Tess4J to function, but they're not packt into Tess4J and therefore must be installed in your UNIX / Linux System. (If you think that's bad then check out Windows Dependency :)
There are Tesseract Binaries for the Major Linux Distributions. You may consider the Version of the installed Tesseract to be compatible with Tess4J.
Make sure those dependencies are met before running Tess4J.

apt-get install tesseract-ocr ghostscript

Windows Dependency

The Tesseract Binaries shipped with Tess4J depend on the Visual C++ Redistributable for VS2013. This dependency must have to be installed on a Windows Machine before running Tess4J.
