[JAVA] A tool that makes a standalone jar an executable file

There are many JVM languages, and each build tool can be grouped into a standalone jar. However, writing java -jar ~ .jar or creating a shell script every time is annoying. Therefore, I made a tool to make jar an executable file with a single command. This article is the 6th day article of VASILY Advent Calendar 2017.

Introduction of tools

jarexe A tool that generates an executable file from a jar file. It is implemented in Go.

Installation

go get github.com/katsuyan/jarexe

Or do a git clone and do a go build.

How to use

jarexe ~.jar

Doing the above will generate an executable with the name of the jar file without the .jar.

option

Each option can be confirmed with the following command.

jarexe -h

change name

jarexe ~.jar --name ...

You can change the name of the generated executable file by adding the name option.

Add java option

jarexe ~.jar --jop "-Xmn120m -Xmx480m -Xms480m"

It is possible to add java options for the example above.

What are you doing

All I'm doing is merging the code that calls my own file with java -jar and the contents of the jar.
