[obar1]

1st test running
error on build ()

error] C:\Users\Mario_Amatucci\gitlab\delta\src\main\scala\org\apache\spark\sql\delta\schema\SchemaUtils.scala:157:44:
[error]       Are you sure that you want to use toUpperCase or toLowerCase without the root locale? In most cases, you
[error]       should use toUpperCase(Locale.ROOT) or toLowerCase(Locale.ROOT) instead.
[error]       If you must use toUpperCase or toLowerCase without the root locale, wrap the code block with
[error]       // scalastyle:off caselocale
[error]       .toUpperCase
[error]       .toLowerCase
[error]       // scalastyle:on caselocale

ans this works

  private def assertLogBelongsToTable(logBasePath: URI): UserDefinedFunction = {
    udf((filePath: String) => {
      if (filePath.isEmpty || new Path(new URI(filePath)).getParent == new Path(logBasePath)) {
        filePath // scalastyle:ignore throwerror
      } else {
        val msg = s"File ($filePath) doesn't belong in the " +
          s"transaction log at $logBasePath. Please contact Databricks Support."
        throw new AssertionError(msg) // scalastyle:ignore throwerror

      }
    })
  }

not the current one
where I get failure on the scalatest thorwerror
