Where can I find gradle dependencies?

Question

I'm trying to learn Gradle in Eclipse.

Is there any good integration where you can search for a Jar to include in the project?

Right now it's a hit-and-miss operation from my side.

Example:

I want to add the CLI library from Apache Commons. Also the Codec library.

I have added both jcenter() and mavenCentral like this:

repositories {
    jcenter()
    mavenCentral()
}

and I have tried this (and variations) in the dependencies section:

compile 'org.apache.commons:cli:1.2'
compile 'org.apache.commons:codec:1.10'

but all I get is

Could not resolve: org.apache.commons:cli:1.2
Could not resolve: org.apache.commons:codec:1.10

When searching in search.maven.org, if I search on org.apache.commons I get 111 pages of hits... I haven't found the time to step thru them all.

When searching for commons-cli, it finds a version from 2005... plus a library called

org.mod4j.org.apache.commons cli

No idea what the "mod4" means.

Is the conclusion that Apache commons doesnt exist in these repositories?

How do you do in these cases? How do you come up with the correct "compile"-specification?

Can I for example say "get latest version of this jar" ?

Would love to have a way to do:

gradle search apache-commons --only-latest-version

or something similar. Something like the wonderful GEM/BUNDLE commands in Ruby.

Thanks for all help

You can search the Maven Central repository to find specific versions of artifacts, but in some cases you have to know the exact name (artifactId) of the artifact. Unfortunately the apache artifacts are not consistent in their groupId or artifactId naming schemes. For example, Apache Commons CLI is commons-cli:commons-cli.

Here is the latest version of that artifact. There is even a convenient panel that shows the exact line to use based on your dependency tool (maven, Gradle, Ivy, etc.)
