maven central pom download fails due to https requirements

[mkmaier]

When trying to build 3.0 locally, the pom download failed, because it used the unsafe default maven central url (probably due to using maven 2.0).
This should fix the pom download in build.xml, but there might be other places where the repo needs to be specified:

-    <artifact:pom id="maven.deploy.pom" file="${maven.deploy.pom}"/>
+    <artifact:pom id="maven.deploy.pom" file="${maven.deploy.pom}">
+      <remoteRepository refid="mvn.maven-central.backup" />
+    </artifact:pom>

Hi,
I was reviewing most places with that issue, but <artifact:pom/> seems to be fallen under the radar. I am quite sure that I did a full bootstrap with empty Maven Cache and Ivy cache, but I will check this again!

What exactly failed? Can you post the full Maven log?

Thanks for reporting.

It would really be good, if Maven releases a "bugfix" Maven Ant Tasks, because this causes headaches also in Apache Lucene and other projects using those to deploy their artifacts to Maven.

I am quite sure this is the only remaining problematic part. The artifact:deploy tasks are no issue. And artifact:mvn got a special bootstrapping already.

Hi,

What exactly failed? Can you post the full Maven log?

I assume it fails to download the parent Sonatype POM?

I was able to reproduce this:

-maven-setup:
    [mkdir] Created dir: C:\Users\Uwe Schindler\Projects\lucene\forbidden-apis\forbidden-apis\build\maven
     [copy] Copying 3 files to C:\Users\Uwe Schindler\Projects\lucene\forbidden-apis\forbidden-apis\build\maven

[artifact:pom] Unable to download the artifact from any repository
[artifact:pom]

I will commit a fix to master branch.

I will add a mental todo: Use https://maven.apache.org/resolver-ant-tasks/ instead. This looks like it also allows to install and deploy files.
