如何将Android Gradle项目的依赖项设置为不同版本的库？

Question

I have small log library and it is published to jcenter. I need to have two versions of the library - debug and release. To do this I found flag publishNonDefault true and pushed new version of library.

Structure of files in repository before flag was set: Structure of files in repository after flag was set:

And now
dependencies { compile 'me.shikhov:wlog:1.3.1' }

gives me error

Error:A problem occurred configuring project ':Project'.
 Could not find wlog.jar (me.shikhov:wlog:1.3.1).
   Searched in the following locations:
      https://jcenter.bintray.com/me/shikhov/wlog/1.3.1/wlog-1.3.1.jar

I have found syntax for local dependency, for example:

debugCompile project(path: ':myLocalLibrary', configuration: 'debug')

releaseCompile project(path: ':myLocalLibrary', configuration: 'debug')

How to set remote library dependency?

The extra string after the version in the artifact name is the classifier.

The classifier allows to distinguish artifacts that were built from the same POM but differ in their content. It is some optional and arbitrary string that - if present - is appended to the artifact name just after the version number. As a motivation for this element, consider for example a project that offers an artifact targeting JRE 1.5 but at the same time also an artifact that still supports JRE 1.4. The first artifact could be equipped with the classifier jdk15 and the second one with jdk14 such that clients can choose which one to use.

Another common use case for classifiers is the need to attach secondary artifacts to the project's main artifact. If you browse the Maven central repository, you will notice that the classifiers sources and javadoc are used to deploy the project source code and API docs along with the packaged class files.

From here .

Gradle dependency declaration takes the form:

[organisation]:[module]:[revision]:[classifier]@[ext]

so you should be consuming the dependency as:

compile 'me.shikhov:wlog:1.3.1:release@aar'
