Dependencies on Cloudera Repo Available with Maven not Gradle

Old Forum

I have the following in a Maven project:

<repositories>
        <repository>
            <id>cloudera</id>
            <url>https://repository.cloudera.com/artifactory/cloudera-repos/</url>
        </repository>
    </repositories>
    <dependencies>
        <dependency>
             <groupId>org.apache.hadoop</groupId>
            <artifactId>hadoop-common</artifactId>
            <version>2.0.0-cdh4.2.0</version>
        </dependency>
    </dependencies>

And that works just fine.

I also have the following in Gradle:

repositories {
    mavenCentral()
    mavenLocal()
    maven {
        url "https://repository.cloudera.com/artifactory/cloudera-repos/"
    }
}
  dependencies {
    compile group: "org.apache.hadoop", name: "hadoop-common", version: "2.0.0-cdh4.2.0"
}

When I run, I get this:

Execution failed for task ‘:run’. > Could not resolve all dependencies for configuration ‘:runtime’.

Could not find org.apache.hadoop:hadoop-common:2.0.0-cdh4.2.0.

:myproject:unspecified

I would love to know what I am doing wrong in my setup.

Thanks.

Can you run with the ‘-i’ switch please. This will provide some information about the network traffic.

Here is the relevant output:

Task ':run' has not declared any outputs, assuming that it is out-of-date.

Interesting Gradle is only looking in certain repos. Here is the full declaration (which I omitted partially before for brevity):

repositories {
    mavenCentral()
    mavenLocal()
    maven {
        url "https://repository.cloudera.com/artifactory/cloudera-repos/"
        url "https://repo.springsource.org/libs-milestone"
        url "http://repo.spray.io"
        url "http://repo.springsource.org/release"
        url "http://repo.typesafe.com/typesafe/repo"
        url "http://download.oracle.com/maven"
    }
}

Thanks.

You’re just replacing the URL value with each subsequent call. You need a separate maven {} block for each repo.

Yes, that was the issue. Thanks for your help.

Out of curiosity, why is it that you can only supply one URL per Maven closure? Not a big deal; just curious what the thinking is behind that.

Thanks again.

Because each repository is one logical object. You may need to configure different credentials to access the repository, or other configuration options.
