org.apache.olingo path is not resolved even after downloading the dependencies

I am trying to create an OData service using apache olingo V4 (https://olingo.apache.org/doc/odata4/tutorials/read/tutorial_read.html)
But when I am creating an Edm(Entity Data Model) provider class by inheriting the class CsdlAbstractEdmProvider of the package org.apache.olingo.commons.api.edm.provider (https://olingo.apache.org/javadoc/odata4/org/apache/olingo/commons/api/edm/provider/CsdlAbstractEdmProvider.html), getting the error The import org.apache can not be resolved
I understand that, I am missing the necessary library to be included in my project. Though I have created this as maven project and edited the pom.xml file as suggested in the tutorial. Even, to avoid any conflict I am using the same naming conventions for the file as been used in the tutorial.
Please suggest me how to deal with this situation. Feel free to ask about any further clarification about the question. Here I am including my pom.xml file

Here is the snapshot of my project folder structure
[Project folder structure]

There was a problem with my maven installation. I installed it separately and set the path variable to C:\ProgramFiles\apache-maven-3.5.0\bin. To be sure you can run mvn -version in command prompt(https://maven.apache.org/install.html).
Thank you

How do I decide the dependencies for my maven project?

As part of learning, this is my first "spring nature" maven project,
In specific, I would like to understand the approach to know the list of dependencies that are required for any "spring nature" maven project, that I work in future.
For this project, here are the list of 21 dependencies that were just dumped into pom.xml without being told about, which dependency to use when, in this training video at 20:50?

So,

What is the approach to know the dependencies required for my "spring nature" project?

Maven projects need dependencies instead of including jar files by build path.when you create a maven project, it requires the library files for the methods you use.you add the dependencies in pom.xml file and when you execute the maven build command the files are automatically downloaded from the internet and included in the project.
You can control the files to download.
you can just add dependencies of the library files you need in your source code.
you decide your dependencies by the methods you use in your source code.
for example.you are using sql database in your project you must need a jar file for the sql driver.
if you have a maven project you just have to add the dependency of the sql in pom.xml

Dependencies list depends on your project nature and usage of .jar relative files.
Simple if you want to use sql in your project then you only need to add sql dependencies in your pom.xml and in the same way if you use junit in your project then you will add junit dependencies in pom.xml in this way after tag
<dependency>
<groupId>junit</groupId>
<artifactId>junit</artifactId>
<version>4.8.2</version>
</dependency>
no need of extra dependencies that are not being used in project.
Note that in maven dependencies repository you will see some extra dependencies. These are ones which maven used for itself or for other dependencies.

The "Spring nature" is related to how your IDE works with Spring plug-in. In eclipse, a "project nature" creates an association between the a project and a tool, plug-in, or feature set. By adding a nature to an eclipse project, you tell an eclipse plug-in that it is configured to use that project. By adding the "Spring Project Nature" to your project, you are enabling eclipse's spring plugin to work with your project.
Add dependencies on need basis. if you don't need hibernate or web-flow don't add it.Its like adding required toppings to your pizza. If you dont want mushroom, dont add it :)

Your projects contains error please fix them before running:Eclipse

You error message says:
... Run Maven->Update Project or Use Quick Fix.
As you see the error is on your Maven Project, you should follow the hint Eclipse is giving you! And Right Click on your Maven Project > Maven > Update Project.
Usually, Eclipse hints are quite usefull.
Read this post to understand what this function is used for. You have to keep in mind that Maven is not the 'native' build manager in Eclipse and therefore needs a little adaptation and additional operations in order for it to work properly.

Maven doesn't install everything from the pom file resulting in "Missing Required Library" x 124

As one of the examples of the problems I am receiving:
Description Resource Path Location Type
Project 'P404EJB' is missing required library: '/home/zeesteen/.m2/repository/com/googlecode/json-simple/json-simple/1.1.1/json-simple-1.1.1.jar' P404EJB Build path Build Path Problem
I assumed that after using the following command:
mvn clean install eclipse:eclipse
Maven was supposed to fetch libraries that are in the pom and not present on my machine yet? (The folders, for example "com" don't exist in the .m2/repository folder)
I have tried multiple solutions myself such as
- Removing the Maven nature, clean installing again, converting to a maven project
- Doing variations on the clean command
- Right clicking on the project and doing Maven > update Project
- Cleaning the project through eclipse
I got 124 Java Build Path Problems like the one mentioned above.

I found the mistake..
Maven didn't give errors because there was nothing wrong with my maven repo apparently. Eclipse had changed the location of my settings.xml maven file to a "nonexistent" location.. Resulting in all the problems. I manually changed it back and all problems are solved.
In Eclipse I did:
Window > Preferences > Maven > User Settings: Field User Settings was wrong
(eclipse changed it..) put it back to where I first made the settings, applied, cleaned the project and everything was fixed!

Please make sure that you have added Maven Dependencies under Libraries in Java Build Path.
Note : You can check the properties by Right-clicking the project and click Properties. If it is NOT added, you can click Add Library and select Maven Managed dependencies and finish

eclipse maven error: Archive for required library in project cannot be read or is not a valid ZIP file

In an eclipse maven project using spring web mvc, I am getting the following error in the Markers tab:
Archive for required library: 'D:/mypath/.m2/repository/javax/transaction/jta/1.0.1B/jta-1.0.1B.jar' in project 'DocumentManager' cannot be read or is not a valid ZIP file
I have checked, and the jar file is in fact present in the url indicated. I even copied a backup of the jar to overwrite the jar file in that location, but that did not get rid of the error either. I forced maven to update, which did not solve the problem. I also restarted eclipse to no effect.
At one point, jta-1.0.1B.jar had been jta-1.0.1B.jar.LatestUpdate, so I shortened the name to jta-1.0.1B.jar
In pom.xml, the location of the error message is line 2, which reads as follows:
xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">
When I download jta-1.0.1B.jar manually from this url, the error in pom.xml goes away but is replaced with new errors in .java class files indicating that 5 methods of the Document class are not valid.
I read this and this, but I am not using struts, I am already including 3.3.2.ga of hibernate, and I do not have a repository tag in pom.xml (which this said did not even solve the problem anyway), so I do not think this is a duplicate.
Can anyone suggest a way to fix this problem? If I need a repository tag, where do I put it? And what else do I change to accommodate its addition?
For anyone who is curious, my pom.xml is included for reference as follows:

To fix issues like that, let Maven download the files again:
Delete the folder D:/mypath/.m2/repository/javax/transaction/jta
Run Maven with -U so it tries broken downloads again.
That should try to download the file again and clean up any "residue" in your local repository.
If Eclipse still complains that the JAR file is corrupt:
Refresh your project (F5 or from the context menu)
Clean the project
Try to open the JAR file. Maybe it's really corrupt.
If the JAR file is corrupt, delete the folder again and run Maven once more. Note the URLs which Maven used to download the archive and contact the administrator of that site.

You can manually go to the repository specified in the error console
that is
Archive for required library: '**D:/mypath/.m2/repository/javax/transaction/jta/1.0.1B/jta-1.0.1B.jar**' in project 'DocumentManager' cannot be read or is not a valid ZIP file
Delete the JAR mentioned
Go to eclipse, right click the project and select run as->maven-install.
It will download the right jar file.

You should exclude JTA in your hibernate dependency.
<dependency>
<groupId>org.hibernate</groupId>
<artifactId>hibernate</artifactId>
<version>3.2.3.ga</version>
<exclusions>
<exclusion>
<artifactId>javax.transaction</artifactId>
<groupId>jta</groupId>
</exclusion>
</exclusions>
</dependency>
After that, add the jta dependency.
<dependency>
<groupId>javax.transaction</groupId>
<artifactId>jta</artifactId>
<version>1.1</version>
</dependency>

The problem with me was fixed by going to Build Path-> Configure Build Path-> Libraries-> Remove the jta lib which has small cross mark on it.
I was able to successfully build my project but was getting this error even after project Refresh/Project Clean.

The maven central repository doesn't contain a jar file for the given groupId/artifactId only a pom.xml.
You are using Spring 3.2 so I suggest you simply upgrade hibernate to the most recent version (4.2.6.Final) which should have a reference to jta 1.1. Or simply include the 1.1 version in your pom which does have a jar in maven central.

To fix this issue simply.
select all libraries in "Maven Dependencies" of related project.
just do "Refresh" of mouse right button...
The reason is cache info, so just refresh the information.
