scala - Jacoco 插件显示 Scala 单元测试的 0% 覆盖率报告

Question

我已经为我的 Spark-Scala 代码编写了单元测试，如下所示

class SparkReaderTest extends FunSuite with BeforeAndAfterAll{
  @transient
  var spark:SparkSession = _
  override def beforeAll(): Unit = {
    spark=
      SparkSession
        .builder()
        .master("local[*]")
        .appName("SparkScalaTest")
        .getOrCreate()
  }
  override  def afterAll(): Unit = {
    spark.stop()
  }
  test("test for utilities for read operations"){
    assert(txtToDFDefault("mockfiles.log",spark).count()>1,"reading raw data")
}
}

这是我的 pom.xml

                </execution>
            </executions>
        </plugin>
        </plugins>

当我运行 mvn package 命令时，我看到运行了 0 个测试

Results :

为什么它显示为 0 个测试运行并且覆盖率也显示为 0%？当我从 intellij 手动运行测试时，我可以看到单元测试成功运行以及覆盖率报告。
