The lastest Gradle distribution (1.0 milestone 9) cannot be selected in the "Install from Gradle.org" drop down list.

I would guess that this is because the Gradle distrubition URL has changed from http://repo.gradle.org/gradle/distributions to http://services.gradle.org/distributions . See the Gradle release note http://wiki.gradle.org/display/GRADLE/Gradle+1.0-milestone-8+Migration+Guide#Gradle1.0-milestone-8MigrationGuide-NewURLfordownloadingGradledistributions .
