Hi all. I am trying to use Maven Embedder 3.0-alpha-2 (latest version to be found on the central repository), and am running into a problem when running a build on a specified POM (see code below) : the POM in question references artefacts which are on our central Archiva repository, accessible by simple http, but the embedder is giving me the following errors, as if it couldn't recognize the protocol :
[WARNING] repository metadata for: 'snapshot com.acme.Parent:1.2-SNAPSHOT' could not be retrieved from repository: http://repo-maven-dsi/archiva/repository/releases due to an error: Unsupported Protocol: '': Cannot find wagon which supports the requested protocol: As you can see, the console reads Unsupported Protocol: '' When I tell the embedder to build a project whose POM is available on my local file system, everything works fine. Here is the code I'm using : package com.acme.dependencyanalyzer; import java.io.File; import java.util.Arrays; import java.util.Iterator; import java.util.List; import java.util.Set; import org.apache.maven.artifact.Artifact; import org.apache.maven.embedder.Configuration; import org.apache.maven.embedder.ConfigurationValidationResult; import org.apache.maven.embedder.DefaultConfiguration; import org.apache.maven.embedder.MavenEmbedder; import org.apache.maven.embedder.MavenEmbedderException; import org.apache.maven.execution.DefaultMavenExecutionRequest; import org.apache.maven.execution.MavenExecutionRequest; import org.apache.maven.execution.MavenExecutionResult; import org.apache.maven.model.Dependency; import org.apache.maven.project.MavenProject; import org.apache.maven.project.MavenProjectBuilder; import org.codehaus.plexus.PlexusContainer; public class ArtefactManager { private static String pomDir = "c:\\\\devhome\\snapshots\\22.0\\VscFwk_1.7_Dev\\dev2_stg\\VscFwk"; //private static String pomDir = "c:\\\\devhome\\workspaces\\Fabien_Workspace_Europa\\maven-dependency-plugin-2.1"; private static String settingsDir = "c:\\\\Documents and Settings\\fabien_coppens\\.m2"; /** * @param args */ public static void main(String[] args) { File user = new File(settingsDir, "settings.xml"); File baseDirectory = new File(pomDir); System.out.println("settings file "+user.toString()); System.out.println("project dir "+baseDirectory.toString()); Configuration configuration = new DefaultConfiguration() .setUserSettingsFile(user) .setClassLoader(Thread.currentThread().getContextClassLoader()); ConfigurationValidationResult validationResult = MavenEmbedder.validateConfiguration(configuration); if (validationResult.isValid()) { try { MavenEmbedder embedder = new MavenEmbedder(configuration); /* MavenExecutionRequest request = new DefaultMavenExecutionRequest() .setBaseDirectory(baseDirectory) .setGoals(Arrays.asList(new String[]{"clean", "install"})); */ MavenExecutionRequest request = defineRequest(baseDirectory); MavenExecutionResult result = embedder.execute(request); if (null == result) { System.out.println("result is null !!"); } if (result.hasExceptions()) { System.out.println("Exceptions in Maven execute result : "+((Exception)result.getExceptions().get(0)).getMessage()); } // ---------------------------------------------------------------------------- // You may want to inspect the project after the execution. // ---------------------------------------------------------------------------- MavenProject project = result.getProject(); if (null == project) { System.out.println("project is null !!"); } // Do something with the project String groupId = project.getGroupId(); String artifactId = project.getArtifactId(); String version = project.getVersion(); String name = project.getName(); List dependencies = project.getDependencies(); if (null != dependencies) { System.out.println("Number of project dependencies : "+dependencies.size()); for (Iterator i = dependencies.iterator(); i.hasNext();) { Dependency dep = (Dependency) i.next(); System.out.println("Dependency "+i+" : "+dep.getArtifactId()); } } List runtimeDependencies = project.getRuntimeDependencies(); if (null != runtimeDependencies) { System.out.println("Number of runtime dependencies : "+runtimeDependencies.size()); for (Iterator i = runtimeDependencies.iterator(); i.hasNext();) { Dependency dep = (Dependency) i.next(); System.out.println("Runtime Dependency "+i+" : "+dep.getArtifactId()); } } Set artifacts = project.getArtifacts(); if (null != artifacts) { System.out.println("Number of artifacts : "+artifacts.size()); for (Iterator i = artifacts.iterator(); i.hasNext();) { Artifact art = (Artifact) i.next(); System.out.println("Artifact "+i+" : "+art.getId()); } } } catch(MavenEmbedderException e) { System.out.println("MavenEmbedderException : "+e.getMessage()); } } else { if (null != validationResult.getUserSettingsException()) { System.out.println("Error occurred in configuration validation : "+validationResult.getUserSettingsException().getMessage()); } else if (null != validationResult.getGlobalSettingsException()) { System.out.println("Error occurred in configuration validation : "+validationResult.getGlobalSettingsException().getMessage()); } else { System.out.println("Error occurred in configuration validation"); } } } private static MavenExecutionRequest defineRequest(File baseDirectory) { MavenExecutionRequest request = new DefaultMavenExecutionRequest() .setBaseDirectory(baseDirectory) .setGoals(Arrays.asList(new String[]{"clean", "install"})); return request; } } --------------------------------------------------------------------- To unsubscribe, e-mail: users-unsubscr...@maven.apache.org For additional commands, e-mail: users-h...@maven.apache.org
