Having troubles building a maven project

Question

I'm getting the following...

[ERROR] Plugin org.apache.maven.plugins:maven-resources-plugin:2.6 or one of its dependencies could not be resolved: Failed to read artifact descriptor for org.apache.maven.plugins:maven-resources-plugin:jar:2.6: 3 problems were encountered while building the effective model for org.apache.maven.plugins:maven-resources-plugin:2.6

  <name>Maven Resources Plugin</name>
  <description>
    The Resources Plugin handles the copying of project resources to the output
    directory. There are two different kinds of resources: main resources and test resources. The
    difference is that the main resources are the resources associated to the main
    source code while the test resources are associated to the test source code.
    Thus, this allows the separation of resources for the main source code and its
    unit tests.

I have, may times. If I change the POM locally in my .m2 removing the parent section and moving the down to just above the it then works properly. Unfortunately, that is only a temporary solution. — GregMa, May 14 '21 at 13:15
The POM you show is not the original POM of the maven resources plugin. The original POM has the following parent definition ` maven-plugins org.apache.maven.plugins 23 ../maven-plugins/pom.xml ` — J Fabian Meier, May 14 '21 at 14:04
unfortunately, I did not put that POM there. It was placed by something else when doing a make — GregMa, May 17 '21 at 20:58
So, what happens? The file is different on MavenCentral. Is it overridden after downloading it by something else? Does the download fail? — J Fabian Meier, May 28 '21 at 15:14
We can't use MavenCentral, all SSL stuff is blocked, thus we have to use an internal repository. I have redownloaded everything from MavenCentral and updated our local repository with the re-downloaded jar files and poms several times. Each time, I get the exact same thing. — GregMa, May 28 '21 at 15:16
So at which exact stage does the wrong POM file come in? Is it already in your internal repository and you copy it from there? What exactly is your process to download the POMs? — J Fabian Meier, May 28 '21 at 15:28
To be honest, I have no idea where it's coming from. I can delete the local repository, do a maven-Verify which grabs all the dependencies and it shows up. — GregMa, Jun 04 '21 at 14:05
Then check all the repositories in your `settings.xml` and your `pom.xml` and see whether they contain the wrong POM. — J Fabian Meier, Jun 04 '21 at 14:39
I gave the POM in the original post, nothing else that has to do with maven anywhere else in the rest of the POM. Settings.xml only contains the redirection to our internal repository overriding maven central. — GregMa, Jun 07 '21 at 13:29
Not sure how to add code in a comment, so added the POM in our repository to the original post. Well, I can't add it to the original post. I'm stuck in the... This looks like code, add it as code. When I do that.... You have more code than details, add more details. I've added 5 lines as just random stuff and it still says I have more code than details. Let me try to just paste it here. org.apache.maven.plugins maven-resources-plugin 2.6 pom — GregMa, Jun 07 '21 at 13:48
