turns out this is actually preventing us from upgrading the sample to 1.1.3 because we use configure on demand for CI, so this is pretty high priority

I’m going to need to rethink the sqldelight gradle lifecycle more. It’s too late to rework things right now but here’s what I think needs to be done:

Right now we rely on projectsEvaluated to add the sqldelight tasks and dependencies to the task graph, this doesnt work for configuration on demand. It’s not super clear why, I’m assuming the time which that callback gets invoked is different with COD and its too late to set task dependencies.

That’s pretty hacky regardless, so probably what we need to do is use task creation callbacks instead of project evaluation callbacks. The original problem was that kotlin multiplatform adds the android compilation tasks late in gradles lifecycle, and projectsEvaluated always invoked after that. Instead we should probably use tasks.whenTaskAdded to add sqldelight task dependencies when the kotlin compilation tasks are added.

There’s also some implications for multi-module here, since module properties are initialized during afterEvaluate blocks, we were assuming they’re set up when creating tasks in projectsEvaluated, but if we switch to task creation that probably won’t hold, so we’ll also need to make sure the downstream sqldelight module is configured, which probably requires more understanding of how gradle implements configure on demand.

I believe this is due to enabling configure on demand in Gradle which somehow breaks the SQLDelight plugin.
