+# Java: Getting Started (Gradle)
+
+A barebones Java app, which can easily be deployed to Heroku.
+
+If you want to use Maven instead of Gradle, see [Java: Getting Started (Maven)](https://github.com/heroku/java-getting-started).
+
+## Deploying to Heroku
+
+Using resources for this example app counts towards your usage. [Delete your app](https://devcenter.heroku.com/articles/heroku-cli-commands#heroku-apps-destroy) and [database](https://devcenter.heroku.com/articles/heroku-postgresql#removing-the-add-on) as soon as you are done experimenting to control costs.
+
+By default, apps use Eco dynos if you are subscribed to Eco. Otherwise, it defaults to Basic dynos. The Eco dynos plan is shared across all Eco dynos in your account and is recommended if you plan on deploying many small apps to Heroku. Learn more about our low-cost plans [here](https://blog.heroku.com/new-low-cost-plans).
+
+Eligible students can apply for platform credits through our new [Heroku for GitHub Students program](https://blog.heroku.com/github-student-developer-program).
+
+This application supports the [Getting Started with Java (Gradle) on Heroku](https://devcenter.heroku.com/articles/getting-started-with-gradle-on-heroku) article - check it out for instructions on how to deploy this app to Heroku and also run it locally.
+
+Alternatively, you can deploy it using this Heroku Button:
+
+[![Deploy](https://www.herokucdn.com/deploy/button.svg)](https://heroku.com/deploy)
+
+For more information about using Java on Heroku, see these Dev Center articles:

+#   Gradle start up script for POSIX generated by Gradle.
+#
+#   Important for running:
+#
+#   (1) You need a POSIX-compliant shell to run this script. If your /bin/sh is
+#       noncompliant, but you have some other compliant shell such as ksh or
+#       bash, then to run this script, type that shell name before the whole
+#       command line, like:
+#
+#           ksh Gradle
+#
+#       Busybox and similar reduced shells will NOT work, because this script
+#       requires all of these POSIX shell features:
+#         * functions;
+#         * expansions «$var», «${var}», «${var:-default}», «${var+SET}»,
+#           «${var#prefix}», «${var%suffix}», and «$( cmd )»;
+#         * compound commands having a testable exit status, especially «case»;
+#         * various built-in commands including «command», «set», and «ulimit».
+#
+#   Important for patching:
+#
+#   (2) This script targets any POSIX shell, so it avoids extensions provided
+#       by Bash, Ksh, etc; in particular arrays are avoided.
+#
+#       The "traditional" practice of packing multiple parameters into a
+#       space-separated string is a well documented source of bugs and security
+#       problems, so this is (mostly) avoided, by progressively accumulating
+#       options in "$@", and eventually passing that to Java.
+#
+#       Where the inherited environment variables (DEFAULT_JVM_OPTS, JAVA_OPTS,
+#       and GRADLE_OPTS) rely on word-splitting, this is performed explicitly;
+#       see the in-line comments for details.
+#
+#       There are tweaks for specific operating systems such as AIX, CygWin,
+#       Darwin, MinGW, and NonStop.
+#
+#   (3) This script is generated from the Groovy template
+#       https://github.com/gradle/gradle/blob/master/subprojects/plugins/src/main/resources/org/gradle/api/internal/plugins/unixStartScript.txt
+#       within the Gradle project.
