Gradle is used. The gradlew (on Windows gradlew.bat) file is a proxy to execute build commands. On first call these files will install the correct version of Gradle on your system. Most commonly used commands:

• creates a jar file from the project, dependencies are not added:

./gradlew jar
# creates into build/libs/triplea-<version>.jar

• creates a self contained jar file from the project, all JAR dependencies are included

./gradlew shadowJar
# creates into build/libs/triplea-<version>-all.jar

• run the application right from the source (no jar is created); this may be used from inside an IDE to debug

./gradlew run
# creates into build/libs/triplea-<version>-all.jar

With the help of the Gradle system any modern IDE support is provided out of box, such as:

• Eclipse - use the Buildship plugin
• Intellij IDEA - out of box integration support (just import project, and specify the settings.gradle file)
• Netbeans - use the Gradle plugin
