Error running Google App Engine Standard via IntelliJ - can't find appengine-web.xml

Question

I'm trying to locally run/debug a Google App Engine Standard app written in Kotlin. Here's the basic stack:

• IntelliJ IDEA Ultimate
• Google App Engine Standard
• Gradle
• Kotlin

I followed these directions: https://cloud.google.com/code/docs/intellij/deploy-local#running_your_application_locally So far so good.

But when I go to run it (via IntelliJ Run menu), I get the following error:

NoSuchFileException during local run: Error occurred during local run. Please first confirm that there is a properly placed appengine-web.xml file. If missing, either use the Cloud Code shortcut action under: 'Tools > Cloud Code > Add App Engine Support > Google App Engine Standard' Or manually generate an appengine-web.xml file in the WEB-INF directory of your module's web resource directory, (show balloon)

Error running '(my run config)': Encountered an error starting the App Engine local development server process.

AFAIK, the file is in the correct place (I even tried deleting it and having Google's plugin regenerate it for me - it put it in the same place/same name).

Any ideas how to fix this error? I've spent 2 days just debugging various tool issues with this stack, but can't get past this one.

UPDATE: Here's the run configuration I'm using.

Answer 1

If you right-click on the project, then click on Open Module Settings.
Under Project Settings click on Artifacts.
Choose your war exploded file.
You should notice that on the Output Layout tab under Available Elements you will need to add your JPA descriptors by double-clicking that. This resolved the issue for me with on this exact error.
