Sets a property by name, or set of properties (from file or
resource) in the project.
Properties are immutable: whoever sets a property first freezes it for the
rest of the build; they are most definitely not variable.
There are five ways to set properties:
By supplying both the name and value attribute.
By supplying both the name and refid attribute.
By setting the file attribute with the filename of the property
file to load. This property file has the format as defined by the file used
in the class java.util.Properties.
By setting the resource attribute with the resource name of the
property file to load. This property file has the format as defined by the
file used in the class java.util.Properties.
By setting the environment attribute with a prefix to use.
Properties will be defined for every environment variable by
prefixing the supplied name and a period to the name of the variable.
Although combinations of these ways are possible, only one should be used
at a time. Problems might occur with the order in which properties are set, for
instance.
The value part of the properties being set, might contain references to other
properties. These references are resolved at the time these properties are set.
This also holds for properties loaded from a property file.
