[hibernate-dev] Build and AnnotationProcessors

[Eric Dalquist]

Just to chime in on the IDE use. While hibernate is on the significantly
complex side of things for OSS projects go most projects I deal with
that are using Maven or Gradle I do just checkout in my IDE and expect
to work.

For 99% of maven projects this is the case, I checkout/clone the
project, import it as a maven project in Eclipse and I'm done. All code
and resources required to build are correctly setup on the classpath and
I'm good to go.

For 99% of gradle project I do something similar but before the import I
just run the gradle eclipse command on the CLI.

Unless I'm going to be doing active development or patching on a project
I don't care about a CLI build, I care about a functional IDE experience
so I can run unit tests and debug code to verify some behavior/problem/bug.

I don't have much to say specifically on the annotation processors
stuff. Right now all the jasig projects use a combination of the
maven-processor-plugin and the build-helper-maven-plugin to get the
meta-model built and added to the classpath. Honestly I don't care how
that happens as long as I can end up with the same final result of maven
knowing about a generated-sources directory and code getting placed
there during the generate-sources build phase.
