  Nebula Extra Configurations Gradle plugin似乎提供了可选项 .

  你会像这样使用它：

  apply plugin: 'java'
  apply plugin: 'nebula.optional-base'
  
  repositories {
      mavenCentral()
  }
  
  dependencies {
      compile 'org.apache.commons:commons-lang3:3.3.2', optional
      compile group: 'log4j', name: 'log4j', version: '1.2.17', optional
  }

  同时您可以使用 pom.withXml 方法修改生成的pom文件，例如添加 <optional> 标签或更改 <scope> 值：

  apply plugin: 'java'
  apply plugin: 'maven-publish'
  
  configurations {
    optional
    compile.extendsFrom optional
  }
  
  dependencies {
    compile 'com.some.group:artifact:1.0';
    optional 'com.another.group:optional-artifact:1.0'
  }
  
  publishing {
    publications {
      maven( MavenPublication ) {
        from components.java
  
        pom.withXml {
          asNode().dependencies.dependency.findAll { xmlDep ->
            // mark optional dependencies
            if ( project.configurations.optional.allDependencies.findAll { dep ->
              xmlDep.groupId.text() == dep.group && xmlDep.artifactId.text() == dep.name
            } ) {
              def xmlOptional = xmlDep.optional[ 0 ];
              if ( !xmlOptional ) {
                xmlOptional = xmlDep.appendNode( 'optional' )
              }
              xmlOptional.value = 'true';
            }
  
            // fix maven-publish issue when all maven dependencies are placed into runtime scope
            if ( project.configurations.compile.allDependencies.findAll { dep ->
              xmlDep.groupId.text() == dep.group && xmlDep.artifactId.text() == dep.name
            } ) {
              def xmlScope = xmlDep.scope[ 0 ];
              if ( !xmlScope ) {
                xmlScope = xmlDep.appendNode( 'scope' )
              }
              xmlScope.value = 'compile';
            }
          }
        }
      }
    }
  }
