Method Detail

getPropertyValue

public java.lang.String getPropertyValue(java.lang.String key,
                                         java.util.Properties properties,
                                         java.util.Properties environment)

Retrieves a property value, replacing values like ${token} using the Properties to look them up. Shamelessly adapted from: http://maven.apache.org/plugins/maven-war-plugin/xref/org/apache/maven/plugin/war/PropertyUtils.html It will leave unresolved properties alone, trying for System properties, and environment variables and implements reparsing (in the case that the value of a property contains a key), and will not loop endlessly on a pair like test = ${test}

Parameters:

key - property key

properties - project properties

environment - environment variables

Returns:

resolved property value

Throws:

java.lang.IllegalArgumentException - when properties are circularly defined
