docker-compose project name restrictions - can not set project name

[paulschuetz]

Setup:

• id "com.avast.gradle.docker-compose" version "0.16.9"
• docker version: 20.10.18
• Docker Compose version v2.10.2

Problem:
It seems like newer versions of docker-compose somewhat restrict the project name (no uppercase characters), see docker/compose#9741. Unfortunately, the project name generated by the gradle-docker-compose-plugin for the following config

dockerCompose {
        isRequiredByIntegrationTest 'docker/docker-compose.yml'
    }

is 1bd882aa0fc45e9fb48ec8510af6c6d8_xxxxxx_integrationTest (notice the uppercase "T")

Therefore when I run the integration tests I get the following error message:
"1bd882aa0fc45e9fb48ec8510af6c6d8_xxxxxx_integrationTest" is not a valid project name.

Therefore, I would suggest this you to not generate project names with uppercase characters as a fix!

Other than that I tried to set the project name manually, like

dockerCompose {
        projectName 'lowercase-only'
        isRequiredByIntegrationTest 'docker/docker-compose.yml'
    }

However this seems to have no effect at all! How can I set the project name correctly? Or why is it not working like that?

The lowercase only policy was introduced in docker-compose version 2.5.0, see https://docs.docker.com/compose/release-notes/#250.
