another for processors. But whatever your option, do not forget to define the service
in the
META-INF/services
project directory that contains the processor.
The following screenshot shows the contents of the file
javax.annotation.processing.Processor
. As the package contains only a
single processor, then it is obvious that we will have a single line in this file as shown
in the following screenshot:
For those using
Maven v2.3.2
, to achieve the project that contains the processors,
they must set the option
<compilerArgument>-
proc:none</compilerArgument>
in the configuration of the plugin
maven-
compiler-plugin
so that the code is properly compiled.
Now you can import the package that contains the annotation in another project and
use it at your convenience. When compiling our preceding
App
class, we have the
following result:
***** Class :com.packt.ch07.App, Annotated
element : size, Kind : FIELD, Message : Make
sure that this element is not null****
***** Class :com.packt.ch07.App, Annotated
element : main, Kind : METHOD, Message :
Nothing has been done****
