Badass-Jar example N-Queens

A simple project that shows how to use the Badass Jar Plugin. It implements a library for solving the N-Queens problem.

The plugin is configured in build.gradle as follows:

plugins {
    id 'java'
    id "org.beryx.jar" version "1.0.0"
    ...
}
...
sourceCompatibility = 1.8
...

Usage

To build a modular jar that targets Java 8 execute:

./gradlew build

The above command does not check the validity of module-info.java. You can convince yourself of this by replacing the content of module-info.java with:

module foo.bar {
    exports bar.foo;
    requires baz.qux;
}

The above gradle command will still succeed, although the new module-info.java is invalid.

To check the validity of module-info.java execute:

./gradlew -PjavaCompatibility=11 build

Note that Travis is configured to run gradle both with and without the javaCompatibility project property:

./gradlew -PjavaCompatibility=11 --no-daemon -i -s build
./gradlew --no-daemon -i -s build
