Hi there. If anyone can help with the following, I'd sure appreciate it: • Get Ivy to set a classpath (cachepath) • Get Maven Artifact Resolver Ant Tasks installed
macOS 10.15.4, Java 11 Details ------- I have this really old ant-based server project I'm trying to update. It uses the org.apache.maven.artifact.ant artifact resolver, and it has served me well in the past. Now it's constantly having issues resolving dependencies (not the ones I specify explicitly, but secondary dependencies). Usually it fails because it's trying to fetch artifacts using http instead of https, even though I've specified my repositories using https. It seems to have a hard-wired "central" pointing to <http://repo1.maven.org/maven2>. I've scoured my drive for a settings.xml file that might be setting this, but can't find one. Looking at the .poms in the artifact chain, I don't see them incorrectly specifying a repository, either (just in case they can). ``` [artifact:dependencies] Downloading: org/jboss/shrinkwrap/resolver/shrinkwrap-resolver-bom/2.2.0/shrinkwrap-resolver-bom-2.2.0.pom from repository central at http://repo1.maven.org/maven2 [artifact:dependencies] Error transferring file: Server returned HTTP response code: 501 for URL: http://repo1.maven.org/maven2/org/jboss/shrinkwrap/resolver/shrinkwrap-resolver-bom/2.2.0/shrinkwrap-resolver-bom-2.2.0.pom [artifact:dependencies] [WARNING] Unable to get resource 'org.jboss.shrinkwrap.resolver:shrinkwrap-resolver-bom:pom:2.2.0' from repository central (http://repo1.maven.org/maven2): Error transferring file: Server returned HTTP response code: 501 for URL: http://repo1.maven.org/maven2/org/jboss/shrinkwrap/resolver/shrinkwrap-resolver-bom/2.2.0/shrinkwrap-resolver-bom-2.2.0.pom [artifact:dependencies] An error has occurred while processing the Maven artifact tasks. [artifact:dependencies] Diagnosis: [artifact:dependencies] [artifact:dependencies] Unable to resolve artifact: Unable to get dependency information: Unable to read the metadata file for artifact 'org.hibernate.validator:hibernate-validator:jar': POM 'org.jboss.shrinkwrap.resolver:shrinkwrap-resolver-bom' not found in repository: Unable to download the artifact from any repository [artifact:dependencies] [artifact:dependencies] org.jboss.shrinkwrap.resolver:shrinkwrap-resolver-bom:pom:2.2.0 [artifact:dependencies] [artifact:dependencies] from the specified remote repositories: [artifact:dependencies] central (http://repo1.maven.org/maven2) [artifact:dependencies] [artifact:dependencies] for project org.jboss.shrinkwrap.resolver:shrinkwrap-resolver-bom [artifact:dependencies] org.hibernate.validator:hibernate-validator:jar:6.1.5.Final [artifact:dependencies] [artifact:dependencies] from the specified remote repositories: [artifact:dependencies] maven-group (https://repo1.maven.org/maven2/), [artifact:dependencies] central (http://repo1.maven.org/maven2), [artifact:dependencies] main.repository (https://repo1.maven.org/maven2), [artifact:dependencies] jboss-public-repository-group (https://repository.jboss.org/nexus/content/groups/public-jboss/) [artifact:dependencies] [artifact:dependencies] Path to dependency: [artifact:dependencies] 1) org.apache.maven:super-pom:pom:2.0 ``` I've tried moving to Ivy, but for some reason Ivy refuses to set my classpath (https://stackoverflow.com/questions/61869872/ant-ivy-wont-set-compile-classpath). After a LOT of googling, I finally tracked down evidence that org.apache.maven.artifact.ant is deprecated, and I should be using org.apache.maven.resolver.ant (Maven Artifact Resolver Ant Tasks) instead. So I tried following the directions [here](https://maven.apache.org/resolver-ant-tasks/) to no avail. ``` $ ant build Buildfile: /Users/rmann/Projects/Personal/SatDB/repo/branches/v1.0/build.xml [taskdef] Could not load definitions from resource org/apache/maven/resolver/ant/antlib.xml. It could not be found. ``` My guess is I don't have the jar file. So I try to track it down, but it's not pre-built, as far as I can tell. I downloaded the sources, but there seems to be no way to build it directly. The build.xml requires the maven ant tasks! As I was writing this, I had the idea to see if the jar was in a maven repo, and I found it [here](https://repo1.maven.org/maven2/org/apache/maven/resolver/maven-resolver-ant-tasks/1.2.0/). Dropping that into ~/.ant/lib fixed the missing task, but now it needs org/eclipse/aether/resolution/ArtifactResolutionException. Why does Ant/Maven need stuff from Eclipse? I've been out of the Java development game for 10 years, but the ecosystem sure seems to be an even bigger mess than it was then. This email only scratches the surface of what I've gone through to try to resurrect this project.
