org.codehaus.plexus.interpolation.Interpolator.interpolate()
See {@link Interpolator#interpolate(String,String,RecursionInterceptor)}.
This method triggers the use of a {@link SimpleRecursionInterceptor}instance for protection against expression cycles. @param input The input string to interpolate @param thisPrefixPattern An optional pattern that should be trimmed fromthe start of any expressions found in the input.
