readfiles-maven-plugin

Read files into maven properties.

Mojo details at plugin info

Just one goal: readfiles sets maven properties to the contents of files. Each file is read fully and the contents are set to maven properties of the same name as the files.

Optionally, the contents of the file can be trimmed of whitespace, or transformed using a series of regular expression patterns and replacements.

Parameter	Default	Property	Description
files			The list of files to read
encoding	UTF-8	${project.build.sourceEncoding}	The character encoding of the file
prefix		${readfiles.prefix}	Prefix each property name with this value
regexReplacements			List of pattern replacements
skip	false	${readfiles.skip}	Skip executing the plugin
trim	false	${readfiles.skip}	Trim whitespace from beginning and end of file

regexReplacement Elements

Parameter	Description
pattern	A java regular expression
replacement	The replaceAll value
