Throwing ClassNotFoundException due to deleted Target folder

I tried adding a dependency in my pom.xml, but turns out it is not what I am looking for so I deleted it in my pom.xml.
This is what I removed
<build>
<plugins>
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-jar-plugin</artifactId>
<version>3.2.2</version>
<configuration>
<archive>
<manifest>
<addClasspath>true</addClasspath>
<mainClass>Log_In</mainClass>
</manifest>
</archive>
</configuration>
</plugin>
</plugins>
</build>
I then tried the Clean option in my Maven project in NetBeans 13 as per what I saw in a tutorial and now I lost every subfolder in my Target folder including the folder where my .class files are located. And so my project is not running anymore and is throwing a ClassNotFoundException.
Error: Could not find or load main class Log_In Caused by:

I'm completely aware that this is my fault for not reading a documentation beforehand. Please help me, any help will be appreciated, thank you.

Its completely okay during maven build process to delete and recreate the target folder.
You only lost generated class files. Your source files (.java) should still exist and if you run a full mvn clean install they will be recompiled and your target folder, .class files and jar assets recreated.

The dependency is in my Maven folder as normally and I can also view the class com.vividsolutions.jt.geom.Geometry in Visual Studio Code so I don't think that it should appear missing. I already tried deleting the dependency from the Maven directory and redownloading it but this did not seem to change anything.
Thanks in advance!

For anyone looking for a possible solution com.vividsolutions.jts has been moved to org.locationtech.jts. Thus you should provide the jar to your maven build instead of trying to download it from maven repository.

How can I fix "JavaFX runtime components are missing" Maven error when I try to run the FormsFX demo in NetBeans 12?

I am trying to run a Maven FX Application Project in NetBeans 12. The default project runs OK, but when I try to run the demo of FormsFX there is an error:

How can I fix this Maven error?

JavaFX removed from standard JDK, so you have to install it for your platform. Please take a look at the getting started guide from openjfx.io: https://openjfx.io/openjfx-docs/

JavaFX Font.loadFont() always null when using Maven

I've been trying to fix the most difficult bug I've ever had and anyone that can help gets 10 cookies. I've made two identical JavaFX applications, one using Maven and one with no build tools. The one that was made without a build tool runs as expected, where the Maven app always returns null on Font.loadFont() and thus it throws a Null Pointer Exception. I've reduced the problem to very simple apps.
Here is the app that doesn't use Maven:
import javafx.application.Application;
import javafx.scene.text.*;
import javafx.stage.Stage;
public class AppWithoutMaven extends Application {
public static void main(String[] args) {
launch(args);
}
#Override public void start(Stage stage) {
Font.loadFont(AppWithoutMaven.class.getResource("Raleway-Medium.ttf").toExternalForm(), 50);
for (String family : Font.getFamilies())
if (family.equals("Raleway Medium"))
System.out.println("The font is loaded");
}
}
The above code's file structure, compilation, and execution:
Now for the problematic part
Here is the nearly identical code from the project USING Maven:
package test.font;
import javafx.application.Application;
import javafx.scene.text.*;
import javafx.stage.Stage;
public class App extends Application {
public static void main(String[] args) {
launch(args);
}
#Override public void start(Stage stage) {
Font.loadFont(App.class.getResource("test/font/Raleway-Medium.ttf").toExternalForm(), 50);
for (String family : Font.getFamilies())
if (family.equals("Raleway Medium"))
System.out.println("The font is loaded");
}
}
Here is the pom.xml, which is probably where I messed up:
<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/maven-v4_0_0.xsd">

I know this is such a weird question and there probably is an easy answer to it. I'm sorta new to Maven so thanks for your patience. If it's worth mentioning, I'm on Ubuntu 18.

If you are using maven, then it tries to get the resource files from the resources folder, and if they aren't there it gives you NPE since it doesn't find the resource. One solution would be to put the font into the resources folder.
Another solution would be to insert the following in your pom.xml then you can let your files in any package.
I haven't tried using the fonts but I did with.fxml and .css files and it works for me.
<build>
<resources>
<resource>
<directory>src/main/java</directory>
<targetPath>${project.build.outputDirectory}</targetPath>
<includes>
<include>**/*.ttf</include>
<!--here you can also insert your .fxml files or .css files for example-->
</includes>
</resource>
<resource>
<directory>src/main/resources</directory>
</resource>
</resources>
</build>

Maven has per default a separate directory for resources:
src/main/resources/test/font/Raleway-Medium.ttf
And then the resource is copied into the jar with path /test/font/Raleway-Medium.ttf.

I am using private repository to fetch all the relevant jars for my project.
I have already tried deleting ~/.m2/repository folder but no luck. I have verified that there are no corrupt jars in my local repository plus this used to run fine till few weeks back and just started throwing this error.
For some strange reason, it now tries to download plexus-utils-1.1.jar after downloading jboss-as-maven-plugin-7.9.Final.jar. This plexus-utils-1.1.jar seems to require that ModelControllerClient class. I have another server setup few weeks back where the same code runs perfectly fine and it never downloads plexus-utils-1.1.jar. So not sure what is wrong in my current setup.
How could I resolve this issue?
EDIT
Adding parent pom.xml

So after going to and fro with what could have possibly gone wrong, I focused my efforts on my private repository. As mentioned in the question, the first step was to verify if there are any corrupt files within my .m2 folder or in my private repo and found there were no corrupt jar files.
Next, I removed jboss-as-maven-plugin folder from within my .m2 folder as this plugin was related to the error. I also removed this artifact from my private repo and tried running my setup again.
This time as the artifact was no longer available on my private repo; it downloaded it from the maven central repo and it proceeded to download other related jar files which this plugin might have required and this time the setup worked fine. This would have worked fine with the private repo if I knew about the other related jars and had them in my private repo.
Regarding why it was working on one of my other servers, on that particular server when I ran the maven deploy command initially then I didn't had the jboss-as-maven-plugin artifact in my private repo so on that server it downloaded all the relevant jar files from maven central repo and it has been using those files ever since from its .m2 folder
