Stefan,

When performing 'gradle apps', we pass several properties into the the ant based apps/build.xml.
(Actually gradle sucks in the apps/build.xml tree and runs internally, but that is an implementation detail).

         def appsJar = project.task("appsJar${t.capital}") {
             doLast() {
               ant.properties['targetBld'] = "$t.name"
               if (!rootProject.ext[t.upper].compileSwing) {
                 ant.properties['JFX_CORE_ONLY'] = 'true'
               }
               ant.properties['jfxbuild.jfxrt.jar'] = jfxrtJar
               ant.properties['platforms.JDK_1.8.home'] = "${rootProject.ext.JDK_HOME}"
               ant.project.executeTarget("sampleAppsJar")
             }
         }

in this case jfxrtJar now evaluates on a 'host' build to:
         build/sdk/rt/lib/ext/jfxrt.jar
and on a cross build to:
         build/${t.name}-sdk/rt/lib/ext/jfxrt.jar

Note in the above the conditional setting of JFX_CORE_ONLY. This is because we are currently not building Swing & SWT classes in the ARM cross builds, and we use the JFX_CORE_ONLY property to avoid trying to build some of the examples.

Our nightly build does quite a bit (but not all) of the apps tree for both 'host' and cross.

I am looking forward to hooking up most of the rest. I think there are a couple that we will not ever build nightly (I think Kevin said Scenebuilder was one).
