Custom doclet in a maven project - invalid flag

I am trying to generate javadoc on my maven project. I am using Java 1.8, and have written a small doclet project. The pom on my project has -
<build>
<plugins>
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-javadoc-plugin</artifactId>
<version>2.9.1</version>
<configuration>

</docletArtifact>
<additionalOptions>
<additionalOption>-views</additionalOption>
</additionalOptions>
<useStandardDocletOptions>false</useStandardDocletOptions>
<destDir>docs</destDir>
</configuration>
</plugin>
</plugins>
</build>
I try to run javadoc:aggregate on this. I get an error
Failed to execute goal org.apache.maven.plugins:maven-javadoc-plugin:2.9.1:aggregate (default-cli) on project <>: An error has occurred in JavaDocs report generation:
[ERROR] Exit code: 1 - javadoc: error - invalid flag: -Xdoclint:none
[ERROR]
[ERROR] Command line was: <javahome/bin>/javadoc #options #packages
Any ideas on what I am doing wrong?
I have been following the Maven page on writing doclets - https://maven.apache.org/plugins/maven-javadoc-plugin/examples/alternate-doclet.html#

Maven Build Failure with "mvn install" command

I was trying to generate and test my codes (if working) for Cucumber-Maven report then opened command prompt. I have tried "mvn clean", it was BUILD SUCCESS. After that, I have tried "mvn install" and encountered BUILD FAILURE (error was shown).

It looks like proxy issue which is blocking the downloads of dependencies, so make some changes in settings.xml or create a one if it is not there.
Goto c:\users\youruser\.m2\settings.xml.
<?xml version="1.0" encoding="UTF-8"?>
<settings xmlns="http://maven.apache.org/SETTINGS/1.0.0"

</settings>

I tried using eclipse. I used maven clean and install for the same POM file. It is working fine.
Seems there is some issue with your C:\users\youruser\.m2\settings.xml file.
May be proxy issues which is blocking maven from downloading dependencies.
Please check your settings.xml file.

How to get the maven shade plugin to use local modules in a multi-module project?

I'm trying to generate an uber jar in a multi module project with the maven-shade plugin with no success.
Versions: maven v3.9, maven-shade v3.0
The project looks as follow:
main
|- library
|- admin
|- ...
The sub module "admin" inherits (dependency) the sub module "library" and contains the maven-shade plugin definition. During the building process the plugin doesn't seem to find the POM of the local sub module "library".
Here are the poms

Javafx project doesn't compile with maven

I have a Java FX project and am using maven 3.0.5 to build. When i run mvn package/install, the project fails and complains that the package javafx.* doesn't exist. Javafx is packaged in Java 1.7 to my understanding so it doesn't make sense that the build does not pick this up. When i compile it within my IDE (intellij) it works fine and after that my maven build also successfully installs, however i do not wish to have to go through the IDE every time i do a clean install. any ideas?
here is my pom:

Thank you for your help.

placing this in the dependencies (depending on where your jdk is) will help the dependency compile, however you should probably replace it with a variable that the user can specify in their settings.xml or maven system properties:
<dependency>
<groupId>com.oracle</groupId>
<artifactId>javaFX</artifactId>
<version>2.2</version>
<scope>system</scope>
<systemPath>C:\Program Files\Java\jre7\lib\jfxrt.jar</systemPath>
</dependency>
see Maven project with JavaFX (with jar file in `lib`) for more details as to why

If you get these errors in a modular project with JavaFx version 17 using Maven, just try the usual things like standing on your head, walking on the ceiling, rotating the Earth in the opposite direction or even reading https://openjfx.io/openjfx-docs/ and then just switch to the version 17.0.1 or later and it should work:
<dependency>
<groupId>org.openjfx</groupId>
<artifactId>javafx-controls</artifactId>
<version>17.0.1</version>
</dependency>

This solution worked for me.
Move sample.fxml to resources folder.
This requires changing your code to getResource("/sample.fxml").
