Thanks a lot Adam for your help!

Unfortunately I forgot that I need also to include some properties file that
are mixed with classes, to do that I've added a second "from" closure:

sourceSets {
        main {
                java {
                        srcDir 'src'
                }
                processResources {
                        from(projectDir) {
                                include 'images/**'
                                include 'jquery*'
                        }
 from(projectDir + '/src') {
                                include '**/*.properties'
                        }
                }
        }
}

Obviously (because I'm not as smart as Gradle :-) ) I get an exception:

$ gradle

FAILURE: Build failed with an exception.

* Where:
Build file '/home/alexyz/schemas/build.gradle' line: 10

* What went wrong:
A problem occurred evaluating root project 'schemaSpy'.
Cause: Could not find method processResources() for arguments
[build_gradle_2bedb9b09af44a1d2902600ce653da5b$_run_closure1_closure2_closu...@efeff8]
on source set main.

How can I cope with this error?

Thanks and regards,
Alessandro
