"wildcardSuites" can't find tests, "suites" can

For full details, see this StackOverflow question.

In short, discovery was failing to find my tests using the wildcardSuites option:

<wildcardSuites>com.cainc.data.etl.schema.proficiency</wildcardSuites>

By succeeds when using just the suites option:

<suites>com.cainc.data.etl.schema.proficiency.ProficiencySchemaITest</suites>

And here's the test class:

class ProficiencySchemaITest extends FlatSpec with Matchers with SharedSparkContext with BeforeAndAfter {
    private var schemaStrategy: SchemaStrategy = _
    private var dataReader: DataFrameReader = _

    before {
        val sqlContext = new SQLContext(sc)
        import sqlContext._
        import sqlContext.implicits._

        val dataInReader = sqlContext.read.format("com.databricks.spark.csv")
                                            .option("header", "true")
                                            .option("nullValue", "")
        schemaStrategy = SchemaStrategyChooser("dim_state_test_proficiency")
        dataReader = schemaStrategy.applySchema(dataInReader)
    }

    "Proficiency Validation" should "pass with the CSV file proficiency-valid.csv" in {
        val dataIn = dataReader.load("src/test/resources/proficiency-valid.csv")

        val valid: Try[DataFrame] = Try(schemaStrategy.validateCsv(dataIn))
        valid match {
            case Success(v) => ()
            case Failure(e) => fail("Validation failed on what should have been a clean file: ", e)
        }
    }
}

When I run mvn test, it can't find any tests and outputs this message:
