Ammonite embedded repl project binary generated using coursier bootstrap process gives an error.

[Poorva17]

Hello,

We are using coursier bootstrap to generate binary executable for our sample ammonite project. We are facing following issue.

Binary generated using coursier bootstrap command fails to run if it generated using publishLocal (0.1.0-SNAPSHOT). On the contrary, binary generated using coursier bootstrap command runs as expected if it is generated using git SHA

We have created sample ammonite project to demonstrate this issue.

Steps to reproduce -
Approach1

sbt publishLocal

Bootstrapping using coursier

./coursier bootstrap -r jitpack --cfa com.github.Poorva17.ammonite-sample:sample_2.12:0.1.0-SNAPSHOT -M example.Main -f -o sample-bootstrap

Running the generated binary executable

Run the executable from the root of the project

./sample-bootstrap

It fails with error

Please note that it ONLY fails in case of publishLocal. Approach 2 and approach 3 works very well

Approach 2 - Ammonite app process runs as expected if used with git SHA as version for coursier to bootstrap.
e.g. -

./coursier bootstrap -r jitpack --cfa com.github.Poorva17.ammonite-sample:sample_2.12:1d3854c -M example.Main -f -o sample-bootstrap

Run the executable from the root of the project

./sample-bootstrap

Approach 3 - It also works as expected when running sbt sample/run from the root directory of the project.

Note -

1. With ammonite version 1.3.2, issue persists with behaviour mentioned.
2. With ammonite version 1.4.4 behaviour is different. In this case, approach 1 fails with following error

We upgraded coursier launcher version to latest - 1.1.0-M10 and with ammonite version 1.6.0. And now we generate sample-bootstrap with command
sbt publishLocal
./coursier bootstrap -r jitpack com.github.Poorva17.ammonite-sample:sample_2.12:0.1.0-SNAPSHOT --embed-files=false -f -o sample-bootstrap
(added flag embed-files=false).
Now it works on my machine but problem is this sample-bootstrap file is not sharable. If I run it on some other machine it fails with error

this appears to be a coursier issue
