What is the current way of getting to a working build? #3

Here's a suggestion for a CONTRIBUTING.md file:

Prerequisites

Before you run ./gradlew build

Since this project uses jOOQ's generated classes we'll first need to generate those. jOOQ requires a database connection to do so, and to make sure the whole team has the same database schema to generate the jOOQ classes from, we use Flyway to perform database migrations.

1) Start the dockerized PostgreSQL using docker-compose with the db/docker-compose.yml file. 1) Run ./gradlew flywayMigrate (by default it uses your postgres running at 5433, aka the test database). 1) Run ./gradlew generateJooq

This should generate classes in build/generated-src/jooq/main under a package of com.gildedrose.db

That last part is not working for me however.

I have a running database, and I can see the items table that was created because of the flyway migration.

But when I run generateJooq, I don't get any generated classes.

What am I still doing wrong?

Hmm, thanks for the file, and it should work! I get

I'm also wondering how your flywayMigrate and jooqGenerate are working, when you've stopped running the database they both connect to. I have not set any environment variables before running those scripts by the way. Just using the defaults.

tim-mortimer commented 4 months ago

I hit the same issue as @Sch3lp, but I think I've found the root cause of the issue.

I found that removing the following line allowed the generateJooq task to build the generated classes: https://github.com/dmcg/gilded-rose-tdd/blob/9de903160635b6db0e0e12abdba6950969dac3d9/build.gradle#L139

That line was added under a commit to improve the build time of the application by caching the generateJooq task. I suspect that @dmcg can't reproduce the issue above because he already had the output cached.
