terraformPlan fails every other time (with single lambda resource)

[blundell]

I'm using the lambda integration from the README, it creates a resource and its the only resource in the whole project.

> Task :my-root-project:my-terraform-project:terraformMainPlan FAILED
╷ IDLE

FAILURE: Build failed with an exception.

I get this failure every 1st build, then I run the same command again (terraformPlan) and it succeeds. Might be something to do with the ordering of when the resources are created vs when my tf file is accessed?

Also in the IDE, the line itself is always declared as an "unresolved" reference.

Will have a look

could you share a repro project?

Created a simple reproduction project https://github.com/blundell/TerraformGradlePluginPlayground/tree/lambda_not_found_repro/backend however it no longer fails every other time (it succeeds every time). But the IDE still shows it as red/missing:

Using the command ./gradlew :backend-terraform:terraformPlan

Indeed the TF IJ plugin does not support yet this setup. I will try to support it as soon as I can.
