Can't generate tests

```sh
cd tests/translator/project
```

This is the build.sbt file:
```sbt
name := "translator"

version := "0.9-SNAPSHOT"

scalaVersion := "2.12.8"

resolvers += "Sonatype OSS Snapshots" at "https://oss.sonatype.org/content/repositories/snapshots"
resolvers += Resolver.sonatypeRepo("public")

libraryDependencies ++= Seq(
  "io.kaitai" % "kaitai-struct-compiler_2.12" % "0.9-SNAPSHOT",
  "com.github.scopt" % "scopt_2.12" % "3.7.1",
  "org.yaml" % "snakeyaml" % "1.16"
)

mainClass := Some("io.kaitai.struct.testtranslator.Main")
```

`sbt run` gives:
```console

Since `kaitai-struct-compiler_2.12-0.9-SNAPSHOT.pom` can't be found, I tried to link mine like this:

```sbt
○ ○ ○
libraryDependencies ++= Seq(
  "io.kaitai" % "kaitai-struct-compiler_2.12" % "0.9-SNAPSHOT" from "file:///home/sealmove/Programming/kaitai_struct/compiler/jvm/target/scala-2.12/kaitai-struct-compiler_2.12-0.9-SNAPSHOT.pom",
○ ○ ○
```

running `sbt run` now gives:
```console

Please help me solve this issue. If I can't generate the tests, I can't continue the Nim backend project :(
