Igor:
great idea; I will look into JDT API;
thank you

*Igor*, hi;
I have an issue when working with output class files:
in my MojoExecutionBuildParticipant I am interested in
resulting
class files,
not java source files; and when my configurator is invoked
by m2e
for incremental build,
the following problem occur:
1) the source file compiles fine, and class file becomes
available,
but there is some kind of timing issue; namely,
form time to time the build() invocation happens
apparently BEFORE the class file is ready form JDT
in the output folder; in other words,
MojoExecutionBuildParticipant
can see modified java file but NOT the corresponding class
file;
what is the way to insure build() is called only when class
file is
ready?
This is odd. Normally, m2e project have Java Builder before Maven
Builder in project configuration, so Maven builder is expected to
see
both changed .java and corresponding generated .class files. If
Maven
Builder is configured to run before Java Builder for whatever
reason,
Maven builder is expected to be invoked twice, before Java Builder
and
after.
Also, keep in mind that you don't have to use Maven Builder. You
can
implement your own project builder or you can use JDT API to
participate
in Java compilation directly.
2) and when the file does not compile
due to a compilation error,
how can I know inside MojoExecutionBuildParticipant
if there will be no class file available at all, despite
java source
change?
There is JDT API that allows you to participate in Java Builder
execution. It may allow you get information about java classes
that
failed to compile or were compiled with errors.
