  Parameters:

  multiLineText - e.g, """ File not found: C: └─Users └─qcq0264 └─eclipse-workspace └─Materials └─src └─main └─groovy └─com └─kazurayam └─materials └─Helpers.groovy """

  Returns:

  a BufferedImage which shows the above text

• static java.awt.image.BufferedImage convertMultiLineTextToImage(java.util.List<java.lang.String> lines)

• static java.awt.image.BufferedImage convertTextToImage(java.lang.String text)

  creates a BufferedImage that shows the given text see http://burnignorance.com/java-web-development-tips/converting-text-to-image-in-java-awt/

• static int copyDirectory(java.nio.file.Path source, java.nio.file.Path target, boolean skipIfIdentical = true)

  Copies descendent files and directories recursively from the source directory into the target directory.

  Parameters:

  source - a directory from which files and directories are copied

  target - a directory into which files and directories are copied

  skipExisting - default to true

  Returns:

• static int deleteDirectory(java.nio.file.Path directory)

  force-delete the directory and its contents(files and directories). Will say again, the specified directory will be removed! If you like to retain the directory, you should use deleteDirectoryContents(Path) method instead. If the specified directory does not exit or is not a directory, then Exception will be thrown

  Parameters:

  directoryToBeDeleted

  Returns:

  number of files deleted, excluding directories deleted

• static void deleteDirectoryContents(java.nio.file.Path directory)

  If the specified directory exists, then delete contained files and child directories while preserving the directory undeleted. If the specified directory does not exit, silently returns while doing nothing.

  Returns:

• static void ensureDirs(java.nio.file.Path directory)

  utility method which creates the directory and its ancestors if not present

  Parameters:

  directory

• static java.lang.String escapeAsJsonText(java.lang.String string)

  This method converts a Java string into a JSON string. This method is implemented with groovy.json.StringEscapeUtils#escapeJava(String)

  Parameters:

  string

  Returns:

• static java.lang.String getClassShortName(java.lang.Class clazz)

  returns a short name of the Class stripping the package. For example, if

  com.kazurayam.ksbackyard.screenshotsupport.ScreenshotRespsitoryImpl

  is given as

  clazz

  , then

  Path - e.g, "C:\\Users\\myname\\eclipse-workspace\\Materials\\src\\main\\groovy\\com\\kazurayam\\materials\\Helpers.groovy"

  Returns:

  List; indented with 2 white space, with branch mark └─. e.g, """ C: └─Users └─qcq0264 └─eclipse-workspace └─Materials └─src └─main └─groovy └─com └─kazurayam └─materials └─Helpers.groovy """

• static void touch(java.nio.file.Path filePath)

  Check if a file is present or not. If not present, create the file of 0 bytes at the specified Path with the current timestamp. This simulate UNIX touch command for a Path
