Add file and pretty console logging

[Larusso]

Description

This patch builds on top of the last addition and prepares a foundation for future tasks with some common settings for logging and console printing.

ConsoleSettings

The console settings config object controls the logoutput of xcodebuild to the standart output. The tool is by nature very verbose and does't allow any verbosity levels to be set except to quiten it completely. In the apple development szene is a tool available to help out with that xcpretty. It's main use is to transform the output of xcodebuild and format it in a shorter more human readable format. It also has formatters to reformat unit test output into different formats. The tool is written in ruby which doesn't help us much so I ported it over to groovy xcpretty.groovy. It is not a 100% port as code snippet colering is missing and only the Simple formatter is supported. This extra library is added and used when prettyPrint is enabled in the console settings object. The logfile written to disk is not formatted!

The console settings can be set on the plugin level for all xcodebuild tasks or individual for each task.

xcodebuild.consoleSettings {
    prettyPrint = true // use xcpretty for console output
    useUnicode = true  // use unicode or ascii output
    colorize = "auto"  // colorize output (always, never, auto)
}

The default values are set based on the gradle console settings which can be changed with the commandline switch --console=(auto,plain,rich,verbose) or via gradle property -Dorg.gradle.console=(auto,plain,rich,verbose)

console setting value	pretty print enabled	unicode enabled	colorized
rich	✅	✅	✅
plain	✅
verbose
auto	✅	✅	✅

because of technical issues with java and gradle it was impossible for me to determine a good value if color output should be enabled or not. Normally one checks if the desired output stream is a tty. This is not possible so I set the rich option as the default because that is what normal invocation will fallback to.

Extension config settings

I added a few config values to the XcodeBuildPluginExtion to set the default log directory, archive directory and derived data directory.

Each xcodebuild task, at the moment only XcodeArchive will bind to these values by default and append the task name to the log file or as a sub directory. The common values can be set in the build.gradle script or via environment variable or gradle property.
