My problem seems to be that it generated an empty META-INF/MANIFEST.MF file. It worked on several examples for me, and today (May 12, 2019) I had my first problem with it. Problems?Ī few people wrote to say that this technique didn’t work for them.
It’s not in a package, so I refer to Foo at the end of the scala command (as opposed to something like my.package.Foo).
EXE TO JAR CONVERTER MAC CODE
I should mention that the Foo.scala file has source code that begins like this: I can then run the application with the scala command like this: Assuming that I start with a Scala source code file named Foo.scala and want to create a JAR file named Foo.jar, the scalac command to create the JAR file looks like this:

The commands I used are the same, except for adding in the classpath complexity.
A more complex exampleĪs a more complicated example I just did a similar thing by creating a one-object application that relies on two JAR files, i.e., two dependencies. The key to this solution is knowing that the scalac “-d” option can be used to create an executable JAR fie. Now you can run/execute the JAR file with the scala command like this: The META-INF/MANIFEST.MF file contains these contents: That creates Hello.jar, whose contents you can look at like this:ħ6 Mon Apr 15 18:45: META-INF/MANIFEST.MFħ51 Mon Apr 15 18:45: Hello$delayedInit$body.class You can compile that source code file directly to a JAR file like this: Given a file named Hello.scala with these contents:

Note that the commands below work on Mac and Linux systems, and should work on Windows with minor changes. If you’re ever working on a really small Scala project - something that contains only a few source code files - and don’t want to use sbt to create a JAR file, you can do it yourself manually.

We haven't encountered any issues throughout our evaluation. It has a good response time and quickly finishes a conversion task, without making the operating system hang, crash or pop up error notifications in the process. The straightforward application runs on a low-to-moderate quantity of CPU and system memory, so it shouldn't burden the computer's overall performance. From the Settings screen you can make the tool automatically overwrite existing files. Once the output directory is established, you can proceed with the compiling procedure with the simple click of a button. Loading a JAR file into the working environment is done with the help of the file browser only, since the "drag and drop" functionality is not supported. It can be seamlessly handled, even by less experienced users.Īfter a brief installation procedure, you are welcomed by a standard window with an uncomplicated layout, representing JAR2EXE Converter's interface.
EXE TO JAR CONVERTER MAC .EXE
Based on the Midp2Exe compiler, JAR2EXE Converter is a simple-to-use program that allows you to create executable files (EXE format) from Java-based items (JAR format), as the name says.
