Question

In maven 2.x, how would one set a plugin\'s property on the command line instead of in the of that plugin in the pom or in settings.xml?

For exampl

Answer 1

The other answers here were not clear to me. This is the way I understand it:

If the plugin code uses a system property for its parameter, then you can define the value on the command line.

There are 3 different ways you can accomplish this in the plugin code:

@parameter expression="${aSystemProperty}" 
@parameter default-value="${anExpression}"
@parameter property="aSystemProperty"

If any or a combination of these methods are used in the plugin code for a particular property, then you can specify a value for the plugin parameter, on the command line. Above code was taken from maven docs here.

If you are using a plugin with the above code, you could specify a value for your property using the following command:

mvn -DaSystemProperty=my-value
