JTS Topology Suite in IntelliJ IDEA

I'm trying to use JTS Topology Suite with ItelliJ (Java) and i'm not able to run even a simple program
I have tried using this POM file but when I modified my POM file I have this error:
Error:(1, 1) java: package org.locationtech.jts.geom does not exist
I have tried even with an empty class to discard other issues:
import org.locationtech.jts.geom.*;
public class geo {}
How should I include JTS in my project?

I just finally do it with this POM file

Intellij cannot find Maven Dependencies in pom.xml

I am new to the spring boot framework and I'm trying to import the Maven libraries, but I keep getting an error with my pom.xml. Please Help!
Failure to transfer org.springframework.boot:spring-boot-starter-parent:pom:2.0.4.RELEASE from https://repo.maven.apache.org/maven2 was cached in the local repository, resolution will not be reattempted until the update interval of central has elapsed or updates are forced. Original error: Could not transfer artifact org.springframework.boot:spring-boot-starter-parent:pom:2.0.4.RELEASE from/to central (https://repo.maven.apache.org/maven2): repo.maven.apache.org
Dependency 'org.springframework.boot:spring-boot-starter-web:' not found less... (Ctrl+F1)

Here is my pom.xml below:
<?xml version="1.0" encoding="UTF-8"?>

This maybe due to the reason that it is not able to connect and transfer dependencies specified in pom.xml file. The details where it is trying to connect must be mentioned in your settings.xml under .m2 folder
Try adding the pluginRepositories in your pom.xml file:
<pluginRepositories>
<pluginRepository>
<id>spring-snapshots</id>
<url>http://repo.spring.io/libs-snapshot</url>
<snapshots>
<enabled>true</enabled>
</snapshots>
</pluginRepository>
</pluginRepositories>
try adding following repository elements inside repositories element in your pom.xml
<repository>
<id>spring-snapshots</id>
<name>Spring Snapshots</name>
<url>https://repo.spring.io/snapshot</url>
<snapshots>
<enabled>true</enabled>
</snapshots>
</repository>
<repository>
<id>spring-milestones</id>
<name>Spring Milestones</name>
<url>https://repo.spring.io/milestone</url>
<snapshots>
<enabled>false</enabled>
</snapshots>
</repository>
If this set well, change your updatePolicy settings.
<repository>
<id>myRepo</id>
<name>My Repository</name>
<releases>
<enabled>false</enabled>
<updatePolicy>always</updatePolicy>
<checksumPolicy>warn</checksumPolicy>
</releases>
</repository>
Refer question.

The problem was I was behind a proxy that was blocking my pom.xml from running properly. After using a VPN to run the application, it works fine now.

Change Your Maven Version Ad Check Again.
Install Maven and Then Go to File/setting/build,execution,.../build Tools/maven
And Change Maven Home Directory to Your Install Maven Directory

when I run my project it gives below exception. I am not sure how to resolve it
[ERROR] Failed to execute goal on project mdm: Could not resolve dependencies for project ai.vroc:mdm:jar:2.0.0-SNAPSHOT: Could not find artifact org.renjin:renjin-script-engine:jar:0.8.2527 in vroc (http://repo.vroc.ai:8081/repository/maven-public/) -> [Help 1]
[ERROR]
The dependency which gives error is in "bedatadriven" repository but it can not find it. I am not sure how to resolve this error.

You need to change this to be a version in your maven repo
<version>0.8.2527</version>
You will need to browse through http://repo.vroc.ai:8081/repository/maven-public yourself since this is not public (at least to me)
Go to org > renjin > renjin-script-engine, then see what versions are there if any

I have to include fixedformat4j-root dependency in my pom.xml.
I get artifact info (group, version, ...) from the pom.xml of the project homepage:
https://github.com/jeyben/fixedformat4j/blob/master/pom.xml
When I store that info to my pom.xml, I got this error from m2e eclipse plugin:

How can I solve this error? Should I set a new repository? Where can I find the repository url from the project pom.xml?

Neither of the repositories you've listed in your POM contain that version of that artifact. They each contain several release versions, but no snapshots.
Looking at the source for this artifact it does appear to be at version 1.4.0-SNAPSHOT but that version has not been deployed to a repository. Either build it yourself locally (via mvn clean install) or reference one of the versions in the given repositories.

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>
