build-dist.gradle

/**
 * This file is an ugly hack.
 * Many non-shared properties are required to publish a release to Maven, and I
 * do not like forcing my developers to put very project-specific data under
 * their home directory ($HOME/.gradle/gradle.properties... I wouldn't ever
 * consider adding it under a Gradle system installation directory).
 * Besides, since Gradle has mandated the single supported file name exactly,
 * it is impossible to make it clear that we are using it for non-shared
 * usage.
 * Therefore, this file uses the output jar of the main 'build.gradle' file
 * to load 'local.properties'.
 * Due to Gradle initialization problems that burn up hours and hours of my
 * life, the 'gradle-javaPropFile-plugin-*.jar' file must be written by
 * 'build.gradle' before this 'build-dist.gradle' file executes...  but there
 * are required interdependencies between the files because 'build-dist.gradle'
 * needs to publish artifacts generated by 'build.gradle'...   Arrrrrrrrrrrg.
 * So, although I am entirely dissatisfied with it, you must build the jar
 * file first with 'build.gradle', then use this build file afterwards to
 * publish to a Maven repository.
