}

project(':subproject1') {
  dependencies {
    compile 'commons-lang:commons-lang:2.6'
    myAdditionalDepList 'com.google.guava:guava:18.0'        
    myAdditionalDepList "com.squareup.retrofit:retrofit:1.9.0"

      project(':subproject1')
      project(':subproject2') {
        dependencies {
          transitive = false                  //true by default
        }
        artifactId = "newSubProject2"         // project name by default
      }
      
      bundlesFrom(project.configurations.myAdditionalDepList)
      bundle('com.squareup.retrofit:converter-jackson') {
        include = false

    }
    testFeature {
      name = 'test-feature-name'
      description = 'Another useful description'
      feature(karafFeatures.features.mainFeature)
    }
  }
}

To generate feature just run

gradle generateKarafFeatures

generated file build/karafFeatures/project1-1.0.0-karaf.xml will look like below

<features xmlns='http://karaf.apache.org/xmlns/features/v1.2.0' name='featuresName'>
  <repository>mvn:group/dependent-feature/1.2.3/xml/features</repository>
  <feature name='main-feature-name' description='Some useful description' version='1.0.0'>
    <feature>dependent-feature</feature>
    <bundle>mvn:commons-lang/commons-lang/2.6</bundle>
    <bundle>wrap:mvn:com.squareup.retrofit/retrofit/1.9.0</bundle>
    <bundle>mvn:com.github/subproject1/1.0.0</bundle>
    <bundle>mvn:com.github/newSubProject2/1.0.0</bundle>
  </feature>
  <feature name='test-feature-name' description='Another useful description' version='1.0.0'>
    <feature>main-feature-name</feature>
  </feature>
</features>

Karaf 4 Support

Karaf 4 features xsd v1.3.0 partially supported

<feature version="1.2.3" dependency="true">dependent-feature</feature>

To generate this stuff

1. Set xsdVersion to 1.3.0
2. Use dependency with configuration closure

karafFeatures {
  name = 'featuresName'
  xsdVersion = '1.3.0'
  outputFile = file("${project.buildDir}/karafFeatures/${project.name}-feature.xml")
  features {
    mainFeature {
      name = 'main-feature-name'
      feature('dependent-feature') {
        dependency = true              //false by default
        version = "1.2.3"              //empty by default
      }
    }
  }
}

generated file build/karafFeatures/project1-feature.xml will look like below

<features xmlns='http://karaf.apache.org/xmlns/features/v1.3.0' name='featuresName'>
  <feature name='main-feature-name' version='1.0.0'>
    <feature version="1.2.3" dependency="true">dependent-feature</feature>
  </feature>
</features>
