Lots of problems resolving maven dependencies in Ant

Rick Mann
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]
[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.

Thanks,

Do you know how to override it in settings? I have this in there already:

                <profile>  
                        <id>mvn-public-repository</id>  
                        <repositories>  
                                <repository>  
                                        <id>maven-group</id>  
                                        <name>Public Maven Repository Group</name>  
                                        <url>https://repo1.maven.org/maven2/</url>  
                                        <layout>default</layout>  
                                        <releases>  
                                                <enabled>true</enabled>  
                                                <updatePolicy>never</updatePolicy>  
                                        </releases>  
                                        <snapshots>  
                                                <enabled>true</enabled>  
                                                <updatePolicy>never</updatePolicy>  
                                        </snapshots>  
                                </repository>  
                        </repositories>  



But maybe the ID needs to be "central"?

Re: Lots of problems resolving maven dependencies in Ant

Davide Grandi
Sorry, but this ant "corner" is out of my paths.

Your idea is worth trying:
--
[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:

Re: Lots of problems resolving maven dependencies in Ant

Rick Mann
In reply to this post by Davide Grandi
Welp, that didn't work. So I downloaded the sources and modified the code (turns out mvn works fine to build it). Now it *KNOWS* it's https, and it still does the wrong thing. I can't figure out where the http: is coming from:

```
$ ant build
Buildfile: /Users/rmann/Projects/Personal/SatDB/repo/branches/v1.0/build.xml
[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

Honestly the repo should just redirect http to https instead of failing with a 501.

So, giving up on Maven Ant Task.

Trying with Ivy, well, it has its own problems: it will try to download a dependency scoped as "provided" in the POM, which I'm fairly certain it should not do.

So, I'd love to try the newer org.apache.maven.resolver.ant, but just try getting that installed! I ended up finding the sources and building it locally. Turns out it, too, has hard-coded http:// URLs, but I fixed those (looks like they're fixed in master but I guess not yet released, pretty serious omission). I've proven I can call this, now to see if I can get all my dependencies satisfied.

Thanks for your help, it prompted me to solve a few problems I'd encountered. I'm still not able to build and deploy my webapp, but I feel like I've made progress.

Re: Lots of problems resolving maven dependencies in Ant

Davide Grandi
I've download and checked ONLY the _source_ package.
Maybe the old URL is ALSO in _bin_ package, maybe in a config file
buried somewhere.

So, if you check the plain binary files, unzipping all the jars (in case
the URL is a resource file ...).

Sorry to be late ...

Cheers,

     Davide

No worries. I've moved on to Maven.

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?
