IMPORTANT: THIS PROJECT HAS MOVED

This project is now archived part of a larger consolidation (more information here). The new primary OpenSHA repository is: https://github.com/opensha/opensha

The instructions below are outdated.

opensha-commons

Base OpenSHA Commons library

Compilation and project configuration

OpenSHA is split into multiple projects with the following dependencies:

Name	Depends On	Description
commons	-	Base commons library (this project)
core	commons	Core OpenSHA library with calculators and models
ucerf3	core	UCERF3 model code and data
apps	ucerf3	GUI applications
dev	apps	Development sandbox for shared prototyping
cybershake	dev	CyberShake interface code and calculators

All users will need to clone the top level commons project, as well as any additional projects of interest. For example, if you need ucerf3 code, you will need to check out ucerf3, core, and commons (ucerf3 depends on core, which in turn depends on commons). Many users will need all projects (except CyberShake).

Requirements

Java 8 JDK or later, 64-bit: Oracle or OpenJDK
Git
- Git is included in the macOS developer tools.
- Windows users may want to consider Git for Windows, which includes a linux-like terminal (Git BASH) in which subsequent commands listed here will work.

Other dependencies are managed with Gradle, which does not require a separate installation. Gradle is clever about finding Java, but some users may have to explicitly define a JAVA_HOME environment variable.

Cloning in a terminal

To clone all projects in a terminal (simplest and quickest for most users):

cd ~/git # create this directory or navigate an alternative directory of your choosing
git clone https://github.com/opensha/opensha-commons.git
git clone https://github.com/opensha/opensha-core.git
git clone https://github.com/opensha/opensha-ucerf3.git
git clone https://github.com/opensha/opensha-apps.git
git clone https://github.com/opensha/opensha-dev.git

Building in a terminal with Gradle

OpenSHA uses Gradle to handle the build process from dependency management to compilation. You should compile OpenSHA from your lowest level project, opensha-dev for the example above.

cd opensha-dev # or whichever project you are interested in
./gradlew assemble

This will build all source files in opensha-dev and parent projects. It will also build a jar file for each project, not including any dependencies. You can build a "fat jar" which includes dependent libraries as follows:

cd opensha-dev # or whichever project you are interested in
./gradlew fatJar

Developing & building OpenSHA with Eclipse

Most active OpenSHA development is done through Eclipse. You will need the Eclipse IDE for Java Developers.

NOTE: The following instructions assume that you have already cloned the OpenSHA projects on a terminal, though you can clone them through Eclipse. If you chose to go this route, be sure to leave the "Import all existing Eclipse projects after clone finishes" check-box UNSELECTED, as this feature will cause issues with gradle.

For each project, you will need to do the following:

File > Import
Select Gradle > Existing Gradle Project and hit Next
Browse to the location of opensha-commons under Project root directory
Hit Finish
Repeat for all sub-projects. IMPORTANT: projects must be imported in order, dependent projects first. commons, then core, then ucerf3, then apps, then dev

You can either use Eclipse's built in Git tools, or the Git command line client to pull/push changes. If any of the .gradle files are modified, right click on the project within eclipse and select Gradle > Refresh Gradle Project
