Gradle - getting the latest release version of a dependency

Question

What would be the easiest way to tell Gradle the following:

Retrieve 'junit' dependency and take its latest 'release' version.

Managing Maven and Ivy repositories is sort of new to me. I tried the following steps and they result in Could not resolve dependency ... error:

• Write compile "junit:junit:latest.release" with repositories set to only mavenCentral() (however, it works if I say "junit:junit:4.10").

• Write compile "junit:junit:latest.release" with repository set the following way:

  ivy {     // I also tried 'http://maven.org' and other possible variants.                url "http://repo1.maven.org"      layout "maven" } 

• Attempted to use Spring Source Ivy repository:

  ivy {     artifactPattern "http://repository.springsource.com/ivy/libraries/release/[organisation]/[module]/[revision]/[artifact]-[revision].[ext]"     ivyPattern "http://repository.springsource.com/ivy/libraries/release/[organisation]/[module]/[revision]/[artifact]-[revision].[ext]" } 

Maybe I misunderstand something. Why would getting the latest version of the dependency be such a hard task?

Answer 1

It can be quite useful sometimes to get the latest release - if for example you release often your own dependencies.

You can get the latest version like

compile "junit:junit:+" 

or better specify at least the major version like

compile "junit:junit:4.+" 

Answer 2

Gradle currently does not support Maven's RELEASE (which is rarely used and deprecated) but it does support Ivy's latest.release. However, the general recommendation is to build against exact versions. Otherwise, the build can become a lottery.
