If you have a pure Java or a Kotlin project we recommend that you use IntelliJ IDEA to build your project since IntelliJ IDEA supports the incremental build which significantly speeds up the building process. You can compile a single file, use the incremental build for a module or a project, and rebuild a project from scratch. IntelliJ IDEA uses a compiler that works according to the Java specification. The IntelliJ IDEA compilation and building process compiles source files and brings together external libraries, properties files, and configurations to produce a living application.

(See Recipe 18.1 for easy ways to do this.) Then place the following code in a file named Main.Compile and build applications with IntelliJ IDEA This is easily demonstrated.įirst, create an empty SBT project directory. This is because class files in the JAR file created by sbt package have dependencies on Scala class files (Scala libraries), which aren’t included in the JAR file SBT generates. DiscussionĪ JAR file created by SBT can be run by the Scala interpreter, but not the Java interpreter.

This can be important if there are license restrictions on a JAR file, for instance.Īs noted, there are other plug-ins to help solve this problem, including One-JAR, but sbt-assembly worked best with several applications I’ve deployed as single, executable JAR files. The sbt-assembly plug-in works by copying the class files from your source code, the class files from your dependencies, and the class files from the Scala library into one single JAR file that can be executed with the java interpreter. Packaging target/BlueParrot-assembly-1.0.jar. Including applescriptutils_2.9.1-1.0.jar Now run sbt assembly to create your single, executable JAR file: See the sbt-assembly project documentation for the latest version and configuration information. The installation instructions for sbt-assembly will probably change, but at the time of this writing (May, 2018), just create a file named assembly.sbt in your SBT project directory with this line:ĪddSbtPlugin("com.eed3si9n" % "sbt-assembly" % "0.14.6")Īfter that, just reload your SBT project. The first two approaches are examined in the Discussion. This solution focuses on the third approach. This requires that Java is installed on client systems.

Use an SBT plug-in such as sbt-assembly to build a single, complete JAR file that can be executed with a simple java command.

Distribute all the JAR files necessary (including Scala libraries) with a script that builds the classpath and executes the JAR file with the java command.

This requires that Scala be installed on client systems.

Distribute all the JAR files necessary with a script that builds the classpath and executes the JAR file with the scala command.

There are three things you can do to solve this problem: This makes it difficult to distribute a single, executable JAR file for your application.

Libraries from the Scala distribution that are needed to execute the JAR file with the java command.

Your project dependencies (JAR files in your project’s lib folder, or managed dependencies declared in build.sbt).

The sbt package command creates a JAR file that includes the class files it compiles from your source code, along with the resources in your project (from src/main/resources), but there are two things it doesn’t include in the JAR file:

Read the background for more background information, or skip ahead to the “Using sbt-assembly” section for details on how to use sbt-assembly. The solution is to use the sbt-assembly plugin. You’re building a Scala application, such as a Swing application, and want to deploy a single, executable JAR file to your users.
