Maven download Artifact form Nexus is endless - maven

I have strange behavior with maven. During my build, the download of the json-smart metadata component (the only artifact that seems to be affected by this problem) loops without ever stopping.

Downloading from nexus: http://mynexus/repository/maven-public/net/minidev/json-smart/maven-metadata.xml
If I pour central maven repo directly it's OK but if I use our Nexus, the problem is still there.
I check certificat, they are OK I check nexus log, there is nothing
about this download Maven Log in debug show nothing elses (just this
final command)
I have use -U and udpatePolicy command in maven setting but nothing (When maven says "resolution will not be reattempted until the update interval of MyRepo has elapsed", where is that interval specified?)
I have clean all json-smart artifact form maven-central repo of our
nexus and task a clean metadata but nothing(Remove artifacts from Nexus repository and how to force sonatype nexus 3 to recreate maven-metadata.xml for maven repository?)
I have no other ideas, has anyone as one ?
Apache Maven 3.6.3
Java version: 11.0.3, vendor: Oracle Corporation
Nexus : 3.6.0-02

We found the solution but no explication on the real problem.
metadata of our json-smart artefact were corrupted on our Nexus and block download from maven. I have delete all composant, invalidate cache of the repository and rebuilt the index and it's seem resolve the problem.

Nexus OSS 3 - UI not showing proxied components

I've installed a fresh new Nexus Repository OSS 3.3.2-02. It has a maven-central repository pre-configured. Without changing anything I just grabbed URL for accessing this proxy repository and added it to my local M2 settings.
When I try building some project, my dependencies are correctly fetched and project built. Here is a look of maven client logs:

The problem is that when I browse Nexus UI I would expect Lombok library to be:
present in Components/Assets view,
searchable.
However, this is not working as the views are empty and search finds nothing.
Please, can you help me find what is wrong? It is the first time I configure Nexus OSS 3 so solution may be very simple.
Thank you very much!
Your maven log shows that the component wasn't downloaded from Nexus:
Downloading: http://repo.maven.apache.org/maven2/org/projectlombok/lombok/1.16.4/lombok-1.16.4.pom
Set up Nexus as a mirror of all repositories in Maven as outlined here:
http://books.sonatype.com/nexus-book/reference3/maven.html#maven-sect-single-group
That will prevent Maven from accessing repositories other than Nexus.

determine if artifact exists in a remote repo without downloading it

This may be similar to: Maven: How to check if an artifact exists?
Except I don't want to determine the existence of the artifact from within a mojo.
I want to know if the artifact exists in my repo preferably just from the command line. (ie mvn some:plugin -Drepo... -Dgroup... -Dversion... -Dartifact... etc.
The reason I want to know this is this: We have a yum repo and we are migrating it to a Sonatype Nexus repo, which is a maven repo under the covers. I don't want to "mvn deploy" a huge rpm only to have it fail because it already exists in the repo. If it exists in the repo, I don't want to deploy it.
Any ideas how I can check if an artifact exists in a maven repo without having to download it first?
The Maven Wagon plugin can determine if an artifact exists if given a URL to a Maven repository:
You will have to build that URL beforehand using groupId, artifactId, etc.
mvn wagon:exist -Dwagon.url=http://repo1.maven.org/maven2/javax/servlet/jstl/1.2
when run within your project, will produce:
[INFO]
[INFO] --- wagon-maven-plugin:1.0-beta-4:exist (default-cli) # proj ---
[INFO] exists.

maven deploy:deploy-file fails (409 Conflict), yet artifact uploads successfully

NOTE:
I now realize that the jar got placed into my repository, but the pom.xml did not. Now, I have another project where the pom.xml fails to get promoted, but the jar is placed in the repository.
However, another project, both the pom.xml and the jar do get placed in the repository.
I have a project in Jenkins where I use the promotion plugin to deploy my artifacts in Maven via the deploy:deploy-file goal.
This works for several other projects I have in Maven, but it fails for this project. The funny thing is that the file (but not the pom.xml) uploads anyway. I've verified this by removing the artifact from our Maven repository, then running the promotion. The artifact is in our repository after the promotion.
Here's the log I'm getting. Broke up the extra long lines the best I could:

I found the problem. Two problems actually:
I only had the release repository setup, and I was attempting to save a snapshot release in the release repository. Artifactory was setup to only allow releases in the release repository. This can be modified in the Artifactory setting, but I decided against this.
My pom.xml has a different version in it than I was trying to save it to. For example, the pom.xml said version 2.0 and I was trying to save the release as 2.0.2. Artifactory rejected the pom (but not the jar) for this reason.
I found the Artifactory setting (which is per repository) that asks whether or not to "Suppress POM consistency checks". Checking this box will allow me to set the version to one, but have the pom say another.
I also had to modify my Maven "settings.xml" file to allow for both a Release and Snapshot repository. I also have to modify my URL to the snapshot repository.
We were only using Ivy for a while (which doesn't have a snapshot concept), so we were just putting stuff in the release repository. This is a Maven project, and the developer marked the version in the POM as a SNAPSHOT.
Unfortunately, Maven documentation is pretty poor, and there still aren't any good books on Maven. Even worse is that the error messages are simply poor. What does "409, ReasonPhrase:Conflict. -> [Help 1]" mean?
Not that Ivy documentation is so much better, but Ant in Action has some excellent sections on using Ivy.
Ensure that you include -SNAPSHOT as part of your version if you are publishing to the snapshot repository.
And remove -SNAPSHOT in case you are publishing it to a non-snapshot repository.
Yeah....Multiple Reason for same error. May be it will help somebody
1. Login as Admin to Artifactory
2. Configuration -> Repositories
3. Edit the Local Repository ---> Suppress POM Consistency Checks
This solves my problem.... Not sure. Right approach or not ?
I also face this problem, and I found the reason is the parent project didn't deploy in the snapshot repository.
I run mvn deploy in the parent folder, and the problem resolved.
Had that error message too. For me the problem was that the setup of the server is to accept only release, not SNAPSHOT. After removing the SNAPSHOT from the pom, it worked fine.
In my case the POM file associated with the jar file (external, in same dir) had a dependency to itself. This was a offline zipped repo from a third party that I needed to load into artifactory.
I modified the POM files, removed the self-dependency and made sure the package info was right. Then artifacts deployed with no problems. Sent email to vendor so they can fix in their build.
I had this issue as well and it turned out that we had include/exclude rules set up on the repository I was trying to deploy to and my deployment didn't match those rules.
My solution was to point the deployment at a new repository that had **/* as the include rule (and the pattern from my other repository as an exclude rule to keep them separate).
I have been experiencing the same problem.
(TL;DR: solution see last line)
During the deploy from jenkins to Artifactory, sometimes (magic!) a 409 - conflict error appeared with the following error message on the Artifactory log:
[WARN ] (o.a.e.UploadServiceImpl:239) - Sending HTTP error code 409: Checksum policy 'LocalRepoChecksumPolicy: CLIENT' rejected the artifact 'gradle-integration:com.redacted.java/fooProject/123/foo-123.jar'. Checksums info: ChecksumsInfo{checksums={SHA-1=ChecksumInfo{type=SHA-1, original='da39a3ee5e6b4b0d3255bfef95601890afd80709', actual='1459689f0be058f4ecef7e6fe3576f1550a8afda'}, MD5=ChecksumInfo{type=MD5, original='d41d8cd98f00b204e9800998ecf8427e', actual='14c7a498de028d6eb5882b3c698bc456'}}}.
As the trained eye might notice: The MD5# d41d8cd98f00b204e9800998ecf8427e is the checksum for an empty file or string.
Which means that the following must be happening:
The copy job that prepares the Artifacts in the publish folder had not finished and therefore the file was empty when the checksum was calculated.
However when the deploy happened the file was there, Artifactory now receives a checksum which is incorrect and correctly refuses the file with the error code 409.
THE SOLUTION (is simple):
Make 100% sure the files are definitely there before you start the deploy job (add a pause or proper logic).
There is a good possibility that the space on your remote repo is full. Verify that before going all technical and wasting time. Wasted 2-3 hrs thinking its a logical problem.
In my case the root cause for that very error was dependency version property that was not in the root pom.
The solution was moving the property to root pom where the version for the dependency was required.
So, missing version property of a dependency.
Very misleading error message indeed.
The world snapshot was written in lower case inside the pom.xml file. It must be written in upper case.

Jenkins Build fails while compiling java code using Maven

I have a Java application and I am able to compile it using maven on CLI, I have a couple of build scripts to deploy the Java code to a remote server and compile the code using Maven but unfortunately the build fails while compiling it using my build script for Jenkins. When I try to compile the code on the remote server the build is successful. The error log is as follows:

I hope I am being clear enough, any help is highly appreciated. I can provide with more details if needed..Thanks in advance!
I think you should try to do the following:
Try to compile the project locally but make sure you're downloading the artifacts from the maven repository. Radically you can do it by renaming your ~user/.m2/repository and running ''mvn clean install''
If it compiles - your local maven is configured properly and its not a pom.xml issue. Also the remote repositories are configured right in maven. In this case its a jenkins issue or rather the issue of maven installed on the same machine with jenkins or maybe some network/security related issue (like a connection to the remote repository is firewalled and not accessible from the jenkins machine and so on).
I would suggest to check out the repository configuration on that maven, or if you want checkout the source code of your project on the jenkins machine and manually run the first step described above from that machine. You should see that the code can't be compiled and get the same error you're getting now.
Now if in during the step 1 the project can't be compiled - its just because you have had a dependency on the lacking module and they were somehow presenting in your local repository (I assume previously it could be compiled locally) and since we're kind of running a clean installation the local repository 'gets purged'. In this case you should find out where do your dependencies come from.
Things like
mvn dependency:tree on the failing module
Can be helpful here.
Hope this will help somehow
2 possible quick solutions:
If it compiles locally, then go to the build configuration on Jenkins and check the "Poll SCM" option to do polling on every build.
Run from the command line on Jenkins server mvn clean install and make sure that the artifacts are available in maven repository after the build. If they are not, download the jars of the relevant versions and put them in the local maven repository (on Jenkins server).
Good luck!
This is what the error message tells you:
The following artifacts could not be resolved:
org.im4java:im4java:jar:1.3.2,
com.aliyun:aliyun-openservices:jar:1.0.0-20120705: Failure to find
org.im4java:im4java:jar:1.3.2 in http://repo.maven.apache.org/maven2
So you have references in your pom for im4java 1.3.2 and aliyun-openservices 1.0.0-20120705, but these cannot be found in the general maven repo. If you do a search for im4java in mvnrepository.com, you'll see that it only has version 1.2, so it is reasonable that it would fail. aliyun-openservices package doesn't exist there at all.
So, where should those be found? Maybe you have installed them locally only and not to Jenkins machine?
What you can do then, is either
(recommended) set up an intranet maven repo where you would deploy the needed libraries and reference that or
install them locally on the machine running Jenkins
Both of these should fix the issue.
A quick look on maven repository, only version 1.2.0 is available and not version 1.3.2 (which you are using).
Does your code compile with a maven build?
I suggest you try to review the repository setting on the jenkins instance

Jenkins (hudson) plugin development meet maven-enforcer-plugin:1.1-SNAPSHOT issue

I try to develop one jenkins (a.k.a hudson) plugin, and follow the Tutorial, and generated source code tree after mvn -cpu hpi:create command.
While when I do "mvn package", it reports error like

From my nexus server, it has maven-enforcer-plugin:1.0 version only, but this dependence is generated from jenkins by default, anyone can help me to solve it ?
(How) Can I change to plugin-1.0 version.
what can I add in nexus server
I just have basic knowledge of maven.
I fixed it by myself by doing two things.
1. Added Apache snapshot from here into my nexus repo group besides those setting in Tutorial
2. It seems my local maven repo is messed up as well, so I can clean it up and reload from nexus.
And it still use maven-enforcer-plugin:pom:1.1-SNAPSHOT plugins.
Hope it helps you as well.
