No standalone-packaged parents found for {slyce-core}

This is my first time trying to do anything with making an intellij plugin, so Im sorry if this is a stupid question.

Here is what happens when I run `slyce-idea-plugin/printProjectGraph`:
```

```

Here is what happens when I run `slyce-idea-plugin/runIDE`
```

Im not sure what to do, my guess is that it cant find the fact that `slyce-core` has dependencies that arent in the project itself?
```scala
lazy val `slyce-core` =
project
.in(file("slyce-core"))
.settings(
name := "slyce-core",
libraryDependencies ++= Seq(
MyOrg %% "klib" % "3.0.0" % "test->test;compile->compile",
"com.lihaoyi" %% "scalatags" % "0.11.1",
),
sonatypeCredentialHost := "s01.oss.sonatype.org",
)
```

Any information would be greatly appreciated, thank you 😄
