Error using docker-compose-example

[a14n]

Describe the bug

Trying to run the docker-compose-example version of fscrawler (after replacing path_to_files_to_scan the good path) I face an error related to io.fabric8:docker-maven-plugin.

Expected behavior

docker-compose up succeeds.

Versions:

• OS: Linux
• Version: master 785b9d8

Hey.

is Docker running on your machine?

[a14n]

Switching back to master the original issue is still there.

$ docker-compose --version
docker-compose version 1.22.0, build f46880fe
$ docker --version
Docker version 20.10.6, build 370c289

[a14n]

git bisect on master with mvn clean package on openjdk:14-alpine it starts failing from 691ddf1 , 0927f27 compiles without error.

If someone faces the same issue you can work around by applying the following diff until a fix land:

diff --git a/contrib/docker-compose-example/Dockerfile-fscrawler b/contrib/docker-compose-example/Dockerfile-fscrawler

Thank you so much for trying everything you can and providing a solution.
I'm starting to look at it as well.

I think that I should completely remove the fscrawler Dockerfile as we are now providing a Docker image on Dockerhub with #1122. That would probably first build faster and then does not need to actually build the project itself...

WDYT?

[a14n]

Removing the dockerfile sgtm as long as we still have a docker-compose file example that works with the image from dockerhub.

BTW thank you really much for this awesome tool you provided 👍
