Making an Archive Fully Executable

[tamalnath]

Spring Boot provides support for fully executable archives. An archive is made fully executable by prepending a shell script that knows how to launch the application. On Unix-like platforms, this launch script allows the archive to be run directly like any other executable or to be installed as a service.

Maven and Gradle plugins currently support this:

• https://docs.spring.io/spring-boot/docs/current/maven-plugin/reference/htmlsingle/#packaging.repackage-goal.parameter-details.executable
• https://docs.spring.io/spring-boot/docs/current/gradle-plugin/reference/htmlsingle/#packaging-executable.configuring.launch-script

Need a way to build a fully executable jar using Bazel.

Interesting, I haven't seen this type of deployment before.

This is the script they use, it is 309 lines, which is pretty big: Spring Boot launcher script

An internal sample service I tried with it, using the maven plugin, failed at startup with InvocationTargetExceptions. I didn't diagnose it further.

I am a bit nervous to jump into this, as it seems like it could be a maintenance/support effort. But it is on the backlog.
