repositories/maven/onlyForConfigurations is not working

Help/Discuss
1

In the below gradle file, I want google-cloud-dialogflow to be fetched from proxy-mavencentral repo. But, it is not doing that and showing the other repo URLs and saying could not find dependency …

Gradle version is 5.6.2 on JDK 1.8

Am I doing any mistake here?

apply plugin: 'java'

sourceCompatibility = 1.8

configurations {
     server
     server_proxyMavenCentral
}

repositories {

   maven {
      url "http://ourlocal.repo/artifactory/ext-release-local"
   }

   maven {
      url "http://ourlocal.repo/artifactory/libs-release-local"
   }

   maven {
      url 'http://ourlocal.repo/artifactory/proxy-mavencentral'
      content {
           onlyForConfigurations 'server_proxyMavenCentral'
      }
   }
}

dependencies {

     compile configurations.server
     compile configurations.server_proxyMavenCentral

     compile group: 'org.apache.logging.log4j', name: 'log4j-api', version: '2.8.1'
     compile group: 'org.apache.logging.log4j', name: 'log4j-core', version: '2.8.1'
     server_proxyMavenCentral 'com.google.cloud:google-cloud-dialogflow:0.116.0-alpha'

}

The issue is that in Gradle there is now a distinction between configurations you use to declare dependencies and configurations that are used to resolve dependencies. That’s one of the reasons why compile (which was used for both things in older versions) is now deprecated and you should prefer api or implementation instead.

For more details see this documentation section on configurations.

So the configurations that actually do resolve when working with java are compileClaspath and runtimeClasspath. Consequently, I think the onlyForConfigurations() API is not suited for your use case. It’s only useful when you define your own thing (e.g. a task) that resolves a custom configuration.

Instead, I would recommend to use some of the other APIs like includeGroup​("com.google.cloud"). You might end up having to do duplicated definitions - like inclusion in one repo and exclusion from the other. We plan to improve this in the future.

If I put

maven {
        url "http://ourlocal.repo/artifactory/proxy-mavencentral"

        content {
            excludeGroup 'net.sf.json-lib' //, 'json-lib'
            excludeGroup 'mysql'
        }
    }

I get below Exception when gradle script runs. The script runs well if the 2 excludeGroup lines are commented

Pls ignore the above comment. Because, It is consisent… Some times it comes and some times it does not. When we add a dependency lib, it comes and if that is removed this exception does not come…

It is very wierd… So, it can be ignored. I will come back with more details…
