Hey ya. In one of my current projects someone decided to use terraform and docker-compose via Gradle. I am currently struggling with a dependency. I have a task defined like that:

tasks {

    val waitServer by creating {
        group = "Docker"
        description = "Spin-up fresh builds via Docker"
        dependsOn (":reconciliation:dockerBuildImage")
        dependsOn(composeUp)
    }
}

So I would expect that ./gradlew waitServer would call dockerBuildImage on the reconciliation module first and then run composeUp. But it goes straight into composeUp which fails because the docker image from the reconciliation module isn’t built yet. Any ideas?

I doubt that the order of the dependsOn statements is guaranteed: if composeUp depends on dockerBuildImage, it should explicitly declare that

Ah. that might be the reason. Interestingly enough, I adopted this from another repository from the same project and I can’t seem to find the reason why it is working on there without any other configuration. But will try to have the dependency explicitly set

Yeaj, having the dependency set on composeUp did the trick. I will check with the colleagues why it works on the other repo anyways. But it really helped me out. Thanks again @araqnid!

It may simply be that the dependencies are put into a HashSet and it happens to work there by chance
