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.

To see the full stack trace of the errors, re-run Maven with the -e switch. Re-run Maven using the -X switch to enable full debug logging.
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.
