Example 1 with PrefixedObjectValueSource

use of org.codehaus.plexus.interpolation.PrefixedObjectValueSource in project maven-plugins by apache.

the class DoapUtil method interpolate.

 * @param value could be null
 * @param project not null
 * @param settings could be null
 * @return the value trimmed and interpolated or null if the interpolation doesn't work.
