Advanced Configuration

Overview

Unlike standard Gradle dependency management, Eta downloads and builds all of its dependencies from source. To integrate into Gradle's infrastructure, we provide a method eta() that can be used in the dependencies block.

Eta Method

The eta() method takes one of the following:

• A variable number of arguments of the form [package-name]:[version-or-version-range]
• It can take a map of keys for specifying Git dependencies

Version Dependency

Exact Version

You can fix an exact version for each dependency.

Example

1
2
3

dependencies {
  compile eta('array:1.2.3.0')
}

Version Range

Example

1
2
3

dependencies {
  compile eta('array:[1.2.3.0,1.2.4.0[')
}

Version Prefix

A version prefix a.b.c.d.+ corresponds to [a.b.c.d.0,a.b.c.(d + 1).0[.

Example

1
2
3

dependencies {
  compile eta('array:1.2.3.+')
}
