mvn_list_goals.sh

This command is to be executed in a maven project folder, where the project pom resides.

• mvn help:effective-pom
  List the effective pom (including all inherited entries)
• 2>/dev/null
  supress stderr output
• grep -i -E '^ *<'
  keep only lines which contain a match for the extended regex given, having zero or more blanks and a lower-than sign at the beginning
• sed --expression 's/ xmlns.="."//g'
  stream edit the output of grep, adding the commands in the sed-script to the edit expressions used when processing the input stream. The script is a substitute following the syntax s/regex/replacement/flags and effectively deletes all (flag /g) found xml namespace attributes as matched by the regex / xmlns.*=".*"/, because replacement is empty (//). Eliminating the namespace from the xml is important for the subsequent xml-processing, since xmlstarlet is picky about proper namespacing of xml tags.
• xmlstarlet sel -t
  process the output of sed, which is clean xml and xslt - transform it into a list of maven-plugins, phases and goals available in the current project.

example output:

Plugin[:phase:goal]
