This is a repackaged open source software product wherein additional charges apply for technical support and maintenance by Apps4Rent. Gradle is an open-source build automation tool that is designed to be flexible enough to build almost any type of software. Gradle avoids unnecessary work by only running the tasks that need to run because their inputs or outputs have changed. Gradle runs on the JVM and you must have a Java Development Kit (JDK) installed to use it. This is a bonus for users familiar with the Java platform as you can use the standard Java APIs in your build logic, such as custom task types and plugins.
