Jcabi-Aether를 사용할 Maven의 settings.xml을로드하십시오.

Question

Maven 및 Jcabi-Aether를 사용하여 일부 아티팩트를 가져 오거나 해결하려고합니다. 나는 준비가 대부분의 코드 있다고 생각하지만 난 힘든 시간 오드 사용할 수 있도록 내가 remotes 변수로 메이븐 저장소를로드 할 수 있도록 사용자의 settings.xml을로드하는 방법을 알아내는 있습니다

import com.jcabi.aether.Aether; 
import java.io.File; 
import java.util.Arrays; 
import org.apache.maven.project.MavenProject; 
import org.sonatype.aether.artifact.Artifact; 
import org.sonatype.aether.repository.RemoteRepository; 
import org.sonatype.aether.util.artifact.DefaultArtifact; 

public class Main { 
    public static void main(String[] args) { 
    File local = new File("/tmp/local-repository"); 
    Collection<RemoteRepository> remotes = Arrays.asList(
     new RemoteRepository(
     "maven-central", 
     "default", 
     "http://repo1.maven.org/maven2/" 
    ) 
    ); 
    Collection<Artifact> deps = new Aether(remotes, local).resolve(
     new DefaultArtifact("junit", "junit-dep", "", "jar", "4.10"), 
     "runtime" 
    ); 
    } 
} 

로드 할 가능을 settings.xml 및 리포지토리 정보를 얻으시겠습니까?

나는 이것을 알아 낸 :

public static final String userHome = System.getProperty("user.home"); 
public static final File userMavenConfigurationHome = new File(userHome, ".m2"); 
public static final String envM2Home = System.getenv("M2_HOME"); 
public static final File DEFAULT_USER_SETTINGS_FILE = new File(userMavenConfigurationHome, "settings.xml"); 
public static final File DEFAULT_GLOBAL_SETTINGS_FILE = 
    new File(System.getProperty("maven.home", envM2Home != null ? envM2Home : ""), "conf/settings.xml"); 

//... 

    SettingsBuildingRequest settingsBuildingRequest = new DefaultSettingsBuildingRequest(); 
    settingsBuildingRequest.setSystemProperties(System.getProperties()); 
    settingsBuildingRequest.setUserSettingsFile(DEFAULT_USER_SETTINGS_FILE); 
    settingsBuildingRequest.setGlobalSettingsFile(DEFAULT_GLOBAL_SETTINGS_FILE); 

    SettingsBuildingResult settingsBuildingResult; 
    DefaultSettingsBuilderFactory mvnSettingBuilderFactory = new DefaultSettingsBuilderFactory(); 
    DefaultSettingsBuilder settingsBuilder = mvnSettingBuilderFactory.newInstance(); 
    settingsBuildingResult = settingsBuilder.build(settingsBuildingRequest); 

    Settings effectiveSettings = settingsBuildingResult.getEffectiveSettings(); 
    Map<String, Profile> profilesMap = effectiveSettings.getProfilesAsMap(); 
    Collection<RemoteRepository> remotes = new ArrayList<>(20); 
    for (String profileName : effectiveSettings.getActiveProfiles()) 
    { 
     Profile profile = profilesMap.get(profileName); 
     List<Repository> repositories = profile.getRepositories(); 
     for (Repository repo : repositories) 
     { 
      RemoteRepository remoteRepo 
       = new RemoteRepository(repo.getId(), "default", repo.getUrl()); 
      remotes.add(remoteRepo); 
     } 
    }
