Maven plugins are not downloading or resolving when I create a new project

I am very new to maven was about to start learning spring with maven but when I created my first project with maven in eclipse this error occurred and I think maven plugins are not getting downloaded. I have tried several solutions from stackoverflow but nothing worked.
Console Window is like :-

Solutions tried so far:-
Installing maven using help > install a new software option
Tried mvn install using cmd
Tried uncommenting proxy tag in setting.xml file
Tried 'https' instead of 'http' in proxy tag in settings.xml file
Tried reinstalling eclipse
and maybe more..

Thanks!

The given ERORR is the cause of the default goal.
ERROR No goals have been specified for this build. You must specify a valid lifecycle phase or a goal in the format : or :[:]:.
Resolution:
Specify any goal in your run configuration for maven build like clear, compile, install, package.
install
...
Could you please refer to the given steps?
Right click on your project.
Click 'Run as' and select 'Maven Build'
Edit Configuration window will open.
write any goal but your problem specific write 'package'
in Goal text box.
Click on 'Run'

There was an issue with the settings.xml file and the solution is:-
Close the eclipse first - try to work in CMD and configure maven there. Remove setting.xml in your user directory if the file exists there.
Download Maven from official site.
Add the path to %MVN_HOME%\bin to the Path env. variable in windows.
open CMD and cd to the folder where you have a pom.xml.
Type: mvn package. 6. Post the output.
Thanks to #MarkBramnik

you have to designate maven goal.
in pom.xml, insert that
<build>
<defaultGoal>install</defaultGoal>
</build>
I guess there is no defaultGoal in your pom.xml.

How to fix "The import org.apache.poi cannot be resolved"

I want to make use of Apache-POI in my code, but am getting an error message The import org.apache.poi cannot be resolved at the import statement
import org.apache.poi.xssf.usermodel.XSSFWorkbook;
I am a beginner with a freshly set up Visual Studio Code v1.30.2, Maven 3.6.0, Java JRE 1.8.0_201.
I have activated the following extensions:
Debugger for Java, 0.16.0
Java dependency viewer, 0.3.0
Java extension pack, 0.5.0
Java test runner, 0.14.0
Language support for Java (TM), 0.37.0
Maven for Java, 0.14.0
I entered these statements in the pom.xml in the dependency section:
<!-- https://mvnrepository.com/artifact/org.apache.poi/poi-->
<dependency>
<groupId>org.apache.poi</groupId>
<artifactId>poi</artifactId>
<version>4.0.1</version>
</dependency>
<!-- https://mvnrepository.com/artifact/org.apache.poi/poi-ooxml -->
<dependency>
<groupId>org.apache.poi</groupId>
<artifactId>poi-ooxml</artifactId>
<version>4.0.1</version>
</dependency>
I've also tried with other POI versions, e.g. 3.10-FINAL.
I'm too new to Java, Maven and VSCode to be sure I've included all the necessary information to point to a solution. Please help me :)
I've run mvn compile, with this result:

I've also pasted the full output of mvn -X compile here
I've pasted my full POM.XML here
In my local folder C:\Users\MYUSERNAME.m2\repository\org\apache there is no subfolder poi.

Thanks all contributors, and especially to #ayZagen (who pointed me towards the pom.xml).
It turns out that I had inserted the dependencies for poi into the dependencies section of
<pluginManagement>
<plugins>
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-checkstyle-plugin</artifactId>
rather than into the correct section <project> <dependencies>.
When I moved my dependencies to the correct section, maven downloads POI and that part of the code compiles.
Sorry for taking people's time over a trivial error. Thank you for helping me to find out, and asking the right questions! This was a very positive experience!

As per the error log there are 2 possibilities
Network issue.
Maven is not able to download the jar files from its repository, so there is no POI library at .m2 folder
Solution: Check the network/ Internet.
Files corrupted. This happens if file(s) got corrupted.
Solution: delete the folder org.apache.poi inside .m2 folder. the Right click on project(from Eclipse) --> Maven --> Update project. Then clean & refresh project, then Run command Maven clean install

EDIT
Try moving poi dependencies to the root dependencies tag.
Run mvn compile
The first time you execute this (or any other) command, Maven will
need to download all the plugins and related dependencies it needs to
fulfill the command. From a clean installation of Maven, this can take
quite a while (in the output above, it took almost 4 minutes). If you
execute the command again, Maven will now have what it needs, so it
won't need to download anything new and will be able to execute the
command much more quickly.
Maven: Getting Started

Maven release:prepare cannot commit parent module

I want to make a release with the maven release plugin in two steps:
1. mvn clean release:prepare
2. mvn release:perform
It worked fine the last two releases, but after changing my IDE from intellij to eclipse I am not able to perform a release this way with apache-maven 3.5.3 and eGit 4.9.2.
The general structure of my project is:
parent-dir
-> pom.xml
-> child1-dir
-> pom.xml
-> child2-dir
-> pom.xml
child1 and child2 contain code and packaging to jar, the parent has packaging goal pom.
Configuration of maven-release-plugin in parent pom.xml:
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-release-plugin</artifactId>
<version>2.5.1</version>
<dependencies>
<dependency>
<groupId>org.apache.maven.shared</groupId>
<artifactId>maven-invoker</artifactId>
<version>2.2</version>
</dependency>
</dependencies>
</plugin>
The plugin updates all poms with correct version #, committs changes and pushes to the remote repository for both child modules. But for the parent module I get the following error at the end of the log:
[INFO] Reactor Summary:
[INFO]

maven-release-plugin [ERROR] fatal: pathspec '' did not match any files

I'm trying to do a release of my OSS library, but I keep running in to a strange issue with the maven-release-plugin. This used to work fine. I've probably updated either Maven or Git but I can't seem to find the right combination to get things working again for the release.
Has anyone run into this issue, and does anyone know of a solution? I'm using the Maven Shade Plugin (which is what is creating the dependency-reduced-pom.xml files in the build.)

The dependency-reduced-pom.xml, as I understand it, is a temporary file used while merging dependencies into an uber-jar, and should not be committed, so I'm confused why maven is trying to add this file at all.
Thanks for any help.

I figured it out, at least a workaround:
Using 'checkModificationExcludes" configuration option of the maven-release-plugin to exclude the dependency-reduced-pom.xml seems to work around the issue, though I'm not sure this is exactly what the property was intended for (the documentation is unclear):
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-release-plugin</artifactId>
<version>2.5.3</version>
<configuration>
<checkModificationExcludes>
<checkModificationExclude>dependency-reduced-pom.xml</checkModificationExclude>
