Hi,
I am starting to use Ivy as part of an infrastructure that will be
provisioning software services in runtime. Services will be identified by an
artifact id (groupId:artifactId[:classifier]:version) and be resolved in
order to instantiate them.
I started trying to use the maven-embedder but became quite shocked to see
the number of dependencies required to resolve transitive dependencies. I
really like the simplicity the Ivy project offers, and would like to see if
I cant get past some initial hurdles. I am sure I have placed these hurdles
in fromt of me, since I know I'm not doing something correctly. I'm hoping
that someone can point to what I'm doing wrong.
(One important aspect of work is I need to obtain the classpath of resolved
artifacts, and have chosen to go the programmatic route as opposed to using
Ant.)
My simple first steps involved creating the Ivy environment and trying to
resolve from the local maven repository. My assumption is that I can use a
Maven pom file directly, and not set up ivy.xml.
File pom = // a provided maven pom
// Create a FileSystemResolver pointing to the local maven repository
FileSystemResolver fsResolver = new FileSystemResolver()
fsResolver.name = "local-maven-repo"
fsResolver.m2compatible = true
fsResolver.local = true
fsResolver.addArtifactPattern(
"${System.getProperty("user.home")}/.m2/repository/[organisation]/[module]/[revision]/[module]-[revision](-[classifier]).jar")
fsResolver.addIvyPattern(
"${System.getProperty("user.home")}/.m2/repository/[organisation]/[module]/[revision]/[module]-[revision](-[classifier]).pom")
settings.addResolver fsResolver
Ivy ivy = Ivy.newInstance(settings)
ivy.getLoggerEngine().pushLogger(new
DefaultMessageLogger(Message.MSG_VERBOSE));
for(String s : ivy.settings.getResolverNames())
println "==== Resolver: ${s}"
DefaultModuleDescriptor md =
DefaultModuleDescriptor.newDefaultInstance(
ModuleRevisionId.newInstance(art.groupId,
art.artifactId + "-caller",
"working"))
DefaultDependencyDescriptor dd =
new DefaultDependencyDescriptor(md,
ModuleRevisionId.newInstance(art.groupId,
art.artifactId,
art.version),
false,
false,
true);
md.addDependency(dd);
def confs = ["default"]
ResolveOptions resolveOptions = new ResolveOptions().setConfs(confs as
String[]);
ResolveReport report = ivy.resolve(ivyFile.toURL(), resolveOptions);
for(ArtifactDownloadReport dlReport : report.allArtifactsReports) {
File f = dlReport.localFile
if(f!=null) {
if(classPath.length()>0)
classPath.append(File.pathSeparator)
classPath.append(f.path)
}
}
I am passing in an artifact that has a defined dependency that needs to be
resolved transitively. Ivy doesnt seem to be able to resolve the dependency:
