This document describes the required software and tools used for developing LexEVS.

Required Software

Below are the required software and tools necessary to build/compile/develop LexEVS.

• Java JDK 8
• Apache Ant 1.9.3
• Apache Maven 3.3.9 (or greater)
• Git 2.9.2 (or greater)

Database

MySQL is used for LexEVS at NCI in production.  This is what we use in development as well.

• MySQL 5.6.x

Additionally, the following lines need to be added to the my.cnf file:

• innodb_file_format=Barracuda
• innodb_file_per_table=true
• innodb_large_prefix=true

Eclipse

We are using Eclipse for our IDE.  The instructions below are for setting up Eclipse.  IntelliJ can also be used, if that is your preferred IDE.

• Download/install "Eclipse IDE for Java Developers".  The latest version that has been used in development is Eclipse 2019-03 (4.11).

Setup

Get the LexEVS project

• Use git to clone the LexEVS project to your local system.
• LexEVS is located here:
  • https://github.com/lexevs/lexevs
• Checkout the latest branch.  Currently it is "v6.5.3".

Build LexEVS

• cd to the "lexevs" directory
• Set (export) some ANT options:

• • export ANT_OPTS="-Xms128m -Xmx8000m -XX"
  • export ANT_OPTS="-Dhttps.protocols=TLSv1.1,TLSv1.2 -Dforce.http.jre.executor=true -Xmx3072m“

• Build the project by running the command "ant"

This will download all the dependencies and build the LexEVS project.

Setup LexEVS in Eclipse
