Empty Site or StringTemplate 'page' was not found

[jeschkies]

Hi 👋

I have the following multi project setup setup:

lazy val `root` = (project in file("./"))
  .settings(
    commonSettings,
    publish / skip := true)
  .enablePlugins(ScalaUnidocPlugin, GhpagesPlugin, ParadoxSitePlugin)
  .settings(
    // Documentation
    paradoxTheme := Some(builtinParadoxTheme("generic")),
    paradox / sourceDirectory := baseDirectory.value / "docs",
    siteSubdirName in ScalaUnidoc := "api",
    addMappingsToSiteDir(mappings in (ScalaUnidoc, packageDoc), siteSubdirName in ScalaUnidoc),
    gitRemoteRepo := "[email protected]:mesosphere/usi.git"
  )
  .aggregate(...)

The Markdown files are in ./docs. When I run sbt makeSitethe dirtarget/siteonly includes the generate API documentation from unidoc and aparadox.json`. What's wrong with the setup?

However, if I put a simple Markdown file in src/main/paradox I get the following error

[error] java.lang.RuntimeException: StringTemplate 'page' was not found for 'usi/target/paradox/html/main/index.html'. Create a template or set a theme that contains one.

There is something not quite right with Paradox' sourceDirectory setting lightbend/paradox#423

@ennru, thanks! That solves the source issue. However, now I have this error

[error] java.lang.RuntimeException: StringTemplate 'page' was not found for '/Users/kjeschkies/src/usi/target/paradox/html/main/index.html'. Create a template or set a theme that contains one.

When I define a new subproject it works. It must be something defined in commonSettings.

I just removed the commonSettings.
