The following blog propose how to fetch an artifact directly from java using ivy (http://developers-blog.org/blog/default/2010/11/08/Embed-Ivy-How-to-use-Ivy-with-Java).
public class IvyArtifactResolver {
public File resolveArtifact(String groupId, String artifactId, String version) throws Exception {
//creates clear ivy settings
IvySettings ivySettings = new IvySettings();
//url resolver for configuration of maven repo
URLResolver resolver = new URLResolver();
resolver.setM2compatible(true);
resolver.setName("central");
//you can specify the url resolution pattern strategy
resolver.addArtifactPattern(
"http://repo1.maven.org/maven2/"
+ "[organisation]/[module]/[revision]/[artifact](-[revision]).[ext]");
//adding maven repo resolver
ivySettings.addResolver(resolver);
//set to the default resolver
ivySettings.setDefaultResolver(resolver.getName());
//creates an Ivy instance with settings
Ivy ivy = Ivy.newInstance(ivySettings);
File ivyfile = File.createTempFile("ivy", ".xml");
ivyfile.deleteOnExit();
String[] dep = null;
dep = new String[]{groupId, artifactId, version};
DefaultModuleDescriptor md =
DefaultModuleDescriptor.newDefaultInstance(ModuleRevisionId.newInstance(dep[0],
dep[1] + "-caller", "working"));
DefaultDependencyDescriptor dd = new DefaultDependencyDescriptor(md,
ModuleRevisionId.newInstance(dep[0], dep[1], dep[2]), false, false, true);
md.addDependency(dd);
//creates an ivy configuration file
XmlModuleDescriptorWriter.write(md, ivyfile);
String[] confs = new String[]{"default"};
ResolveOptions resolveOptions = new ResolveOptions().setConfs(confs);
//init resolve report
ResolveReport report = ivy.resolve(ivyfile.toURL(), resolveOptions);
//so you can get the jar library
File jarArtifactFile = report.getAllArtifactsReports()[0].getLocalFile();
return jarArtifactFile;
}
}
I'm wondering if sbt exposes this kind of interface since it uses ivy.
resolve :: ModuleId -> File
