Alloy 4 is a self-contained executable, which includes the Kodkod model finder and a variety of SAT solvers, as well as the standard Alloy library and a collection of tutorial examples. The same jar file can be incorporated into other applications to use Alloy as an API, and includes the source code. See the release notes for details of new features.
More documentation can be found at: http://alloy.mit.edu/alloy/documentation.html.
Checkout the project and type ./gradlew. You find the executable JAR in org.alloytools.alloy.dist/target/org.alloytools.alloy.dist.jar after the build has finished.
$ java version # requires 1.8 (and NOT 1.9, gradle does not run on 1.9)

$ git clone git@github.com:AlloyTools/org.alloytools.alloy.git
$ cd org.alloytools.alloy

$ java -jar org.alloytools.alloy.dist/target/org.alloytools.alloy.dist.jar

Note: if you are behind a proxy, the call to gradlew is likely to fail, unless you pass it further options about the http and https proxies (and possibly your login and password on this proxy). There are several ways to pass these options, a simple one is to type (replace the XXXXX's by the adequate settings):
$ ./gradlew -Dhttps.proxyHost=XXXXX -Dhttp.proxyHost=XXXXX -Dhttp.proxyPort=XXXXX \
-Dhttps.proxyPort=XXXXX -Dhttp.proxyUser=XXXXX -Dhttp.proxyPassword=XXXXX \
-Dhttps.proxyUser=XXXXX -Dhttps.proxyPassword=XXXXX \
build
The Alloy build is using a bnd workspace setup using a maven layout. This means it can be build with Gradle and the Eclipse IDE for interactive development. Projects are setup to continuously deliver the executable.
The workspace is divided into a number of projects:
- cnf – Setup directory. Dependencies are specified in [cnf/central.xml] using the maven POM layout
- org.alloytools.alloy.application – Main application code includes the parser, ast, visualiser, and application code
- org.alloytools.alloy.dist – Project to create the distribution executable JAR
- org.alloytools.alloy.extra – Models and examples
- org.alloytools.kodkod.core – Kodkod without native code
- org.alloytools.kodkod.native – The native code libraries for kodkod
This workspace uses bnd. This means that the following have special meaning:
- cnf/build.xml – Settings shared between projects
- ./bnd.bnd – Settings for a project. This file will drag in code in a JAR.
- cnf/central.xml – Dependencies from maven central
The workspace is setup for interactive development in Eclipse with the Bndtools plugin. Bndtools can be installed from the Eclipse Market place (see Help/Marketplace and search for Bndtools).
Bndtools will continuously create the final executable. The projects are setup to automatically update when a downstream project changes.
In the root of this workspace type ./gradlew. This is a script that will download the correct version of gradle and run the build scripts. For settings look at [gradle.properties] and [settings.gradle].
The workspace is setup to build after every commit using Travis. It releases snapshots to https://oss.sonatype.org/content/repositories/snapshots/org/alloytools/ for every CI build on Travis.
Currently only the executable jar in org.alloytools.alloy.dist/target/org.alloytools.alloy.dist.jar is build. In the org.alloytools.alloy.dist project, run ../gradlew macos. This will leave the PKG file in target/bundle.
