Maven failing to download artifact from central repository

I have two private JFrog repositories setup. One repository handles releases and the other handles snapshots. Here is how I have defined this in my settings.xml file.
<settings>
<activeProfiles>
<activeProfile>default</activeProfile>
</activeProfiles>
<servers>
<server>
<id>central</id>
<username>private-repo-username</username>
<password>private-repo-password</password>

<username>private-repo-username</username>
<password>private-repo-password</password>
</server>
</servers>

Multiple of my internal dependencies in my multi-module maven project are getting this error:
[ERROR] Failed to execute goal on project platform-utils: Could not resolve dependencies for project
design.colspalinva:platform-utils:jar:2.2.1-SNAPSHOT: The following artifacts could not be resolved:
com.maxmind.geoip2:geoip2:jar:2.12.0, org.apache.ant:ant:jar:1.10.5: Could not find artifact
com.maxmind.geoip2:geoip2:jar:2.12.0 in central (https://my-private-repo.jfrog.io/artifactory/libs-
release) -> [Help 1]
From the look of it, it doesn't appear that Maven is trying to reach out to the official Maven Central repo for those dependencies, rather failing on my private repository. I was under the impression that if the private repository does not contain the specific artifact, it will attempt to reach out to Maven Central.
It has no problem downloading my Spring dependencies from Maven Central.

If you like to redirect all access of central from Maven to your own repository manager you have to configure the settings.xml as follows:
<! language:language-xml ->
<?xml version="1.0" encoding="UTF-8"?>
<settings
xmlns="http://maven.apache.org/SETTINGS/1.0.0"

The Maven settings.xml configuration you shared seems to be OK. You are overriding the built-in central and snapshot repositories of Maven, which is the correct way to make sure that Maven send requests by default to Artifactory.
Adding a Mirror Any setting, as suggested in the other answer, means that in addition to overriding built-in Maven repositories, you can use the Mirror Any setting to redirect all requests to a Maven repository through Artifactory, including those defined inside POMs of plug-ins and third party dependencies.
According to the log you shared Maven does attempt to resolve the artifacts via Artifactory - https://my-private-repo.jfrog.io/artifactory/libs-release
The issue seems to be related to resolution of a specific artifact(s)in Artifactory.
I'm assuming that libs-release is a virtual Maven repository and that it contains at least one remote Maven repository pointing at Jcenter or Maven Central (if not please start by looking at Maven Repositories).
To debug the issue:
(1) Try resolving the artifact directly from Artifactory using cURL or a web browser, for example:
curl -Uuser:pass https://my-private-repo.jfrog.io/artifactory/libs-release/com/maxmind/geoip2/geoip2/2.12.0/geoip2-2.12.0.jar
(2) If you manage to resolve the artifact, it mean that Artifactory is properly configured and Maven should be able to resolve. If not, try looking for the reason performing a trace, for example:
curl -Uuser:pass https://my-private-repo.jfrog.io/artifactory/libs-release/com/maxmind/geoip2/geoip2/2.12.0/geoip2-2.12.0.jar?trace

How to pass arguments via command line to maven settings.xml?

I need to activate profiles based on environment specifics in Spring Boot Maven application. I configured profiles in settings.xml
<profiles>
<profile>
<id>dev</id>
<activation>
<activeByDefault>false</activeByDefault> </activation>
<repositories>
<repository>
<id>devRepo</id>
<url>https://customRepo/maven/v1</url>
<releases>
<enabled>true</enabled>
<updatePolicy>always</updatePolicy>
</releases>
<snapshots>
<enabled>true</enabled>
<updatePolicy>always</updatePolicy>
</snapshots>
</repository>
</repositories>
</profile>
<profile>
<id>qa</id>
<activation>
<activeByDefault>false</activeByDefault> </activation>
<repositories>
<repository>
<id>qaRepo</id>
<url>https://customRepo2/maven/v1</url>
<releases>
<enabled>true</enabled>
<updatePolicy>always</updatePolicy>
</releases>
<snapshots>
<enabled>true</enabled>
<updatePolicy>always</updatePolicy>
</snapshots>
</repository>
</repositories>
</profile>
</profiles>
I tried by activating the profiles using commands -Pdev
mvn spring-boot:run -s settings.xml -D"spring-boot.run.profiles"=dev help:active-profiles
But profiles are not activated properly. But It's working by adding activeprofiles tags.
<activeProfiles>
<activeProfile>dev</activeProfile>
</activeProfiles>
But I need to activate the profiles environment specific like
<activeProfiles>
<activeProfile>$env</activeProfile>
</activeProfiles>
Any way we can pass arguments to activeProfile in settings.xml file? Similar like this -Denv
Reference:
Maven: How do I activate a profile from command line?
Configure active profile in SpringBoot via Maven
https://mkyong.com/maven/maven-profiles-example/
http://maven.apache.org/settings.html

Pay attention to this line of description:
"Activation occurs when all specified criteria have been met, though not all are required at once." from http://maven.apache.org/settings.html in Profiles section
and consider to define application.properties in your project and add line with this config:
spring.profiles.active=#spring.profiles.active#
I hope this work.

Eclipse Maven Not Downloading Sources and Javadoc from Configured Nexus Repository

I have configured in my global m2 settings the Nexus Repository that my organization is using.
When doing mvn install it downloads the packages from the Nexus Repo, which shows the configuration is alright.
When using maven in eclipse however, it appears that whenever I do a Maven > Update Project, and eclipse tries to download the new packages added in pom.xml, it is still downloading from Maven Repo.
I have already configured the following:
Under Preferences > Maven > Installations, this is pointing to my maven files
Under Preferences > Maven > User Settings, this is pointing to my settings.xml under my user folder and configured to the nexus repository
However, I am not sure why are packages still not retrieved from nexus repo still.
My settings.xml
<settings>
<profiles>
<profile>
<id>MyId</id>
<repositories>
<repository>
<id>MyRepo</id>
<url>MyCompanysNexusRepoUrl</url>
</repository>
</repositories>
<pluginRepositories>
<pluginRepository>
<id>MyRepo</id>
<url>MyCompanysNexusRepoUrl</url>
</pluginRepository>
</pluginRepositories>
</profile>
</profiles>
<activeProfiles>
<activeProfile>MyId</activeProfile>
</activeProfiles>
</settings>

The settings.xml for using a repository manager like Nexus should look like this:
<settings>
<mirrors>
<mirror>
<!--This sends everything else to /public -->
<id>nexus</id>
<mirrorOf>*</mirrorOf>
<url> MyCompanysNexusRepoUrl</url>
</mirror>
</mirrors>
<profiles>
<profile>
<id>nexus</id>
<!--Enable snapshots for the built in central repo to direct -->
<!--all requests to nexus via the mirror -->
<repositories>
<repository>
<id>central</id>
<url>http://central</url>
<releases><enabled>true</enabled></releases>
<snapshots><enabled>true</enabled></snapshots>
</repository>
</repositories>
<pluginRepositories>
<pluginRepository>
<id>central</id>
<url>http://central</url>
<releases><enabled>true</enabled></releases>
<snapshots><enabled>true</enabled></snapshots>
</pluginRepository>
</pluginRepositories>
</profile>
</profiles>
<activeProfiles>
<!--make the profile active all the time -->
<activeProfile>nexus</activeProfile>
</activeProfiles>
</settings>

If you are working in a network with restriction, you might have to add proxy details in eclipse.

Resource nexus-maven-repository-index.properties does not exist

I'm using a remote artifactory repo.
I add this repo to settings.xml file wich plased in the <user>/.m2/ folder:
<settings>

In Idea settings in the "Build Tools -> Maven -> Repositories" page I see url to my artifactory repo. But when I click on "Update" button, I get error message
java.lang.RuntimeException: java.io.FileNotFoundException: Resource nexus-maven-repository-index.properties does not exist
How to solve this trouble?

Maven 3.2.1

Have you tried bumping the memory for the importer then restarting the IntelliJ? (worked for me)
Build, Execution, Deployment → Build Tools → Maven → Importing → VM options for importer

Using SdmxSource jar files in the Nexus Repository through maven (m2eclipse)

The error Missing artifact org.sdmxsource:SdmxApi:jar:1.2.7 appears when defining dependencies in the m2eclipss.
I used this definition:
<dependency>
<groupId>org.sdmxsource</groupId>
<artifactId>SdmxApi</artifactId>
<version>1.2.7</version>
</dependency>
What may cause such a problem? Is there another way to import packages from nexus repository(eclipse IDE)?
Thanks in advance

Have you tried manually downloading the dependencies? See the sdmxsource help page: http://www.sdmxsource.org/sdmxsource-java/.
You could also use the parent tag in pom file:
<parent>
<artifactId>SdmxSourceBase</artifactId>
<groupId>org.sdmxsource</groupId>
<version>1.5.3</version>
</parent>
And the following repository in the maven settings.xml file:
<profiles>
<profile>
<id>sdmxsource</id>
<repositories>
<repository>
<id>MTRepo</id>
<url>http://sdmxsource.metadatatechnology.com/nexus/content/repositories/releases</url>
<snapshots>
<enabled>false</enabled>
</snapshots>
<releases>
<enabled>true</enabled>
</releases>
</repository>
</repositories>
</profile>
</profiles>
<activeProfiles>
<activeProfile>sdmxsource</activeProfile>
</activeProfiles>
