In this article, we will discuss the introduction to Maven configuration properties, maven configuration properties plugin, plugin configuration options, front end goal parameters. The majority of customizable properties are configured through the Vaadin Maven plugin. These can be configured either as system attributes or as plugin configuration options. Now let's discuss the maven configuration plugins with an example.
Maven configuration properties plugin
The plugin is the ideal place to set persistent configuration properties for a Maven project.

</plugin>
Plugin configuration options
All maven configuration properties are listed below along with their default settings:
Application Properties

frontend directory
the folder containing the front-end source code for the project. "$project.basedir/frontend" is the default value.
generated folder
the location of the folder where Webpack will find created files from Flow. "$project.build.directory/frontend" is the default.
Generated Ts Folder
the location of the TypeScript API files for client projects in Flow. "$project.basedir/frontend/generated" is the default.
Java source folder
"$project.basedir/src/main/java" is the default value.
Java resource folder
"$project.basedir/src/main/resources" is the default value.

project build dir
project build dir is the project's build directory. is set to $project.build.directory by default.
Build front-end goal parameters
The build-frontend objective also uses the following parameters.
Generate Bundle
if the project front-end sources should be used to create a bundle. Usually sets to true.
Run Npm Install
if the npm install step should be executed after upgrading dependencies. In the event that appears to be up to date, this may not always carry out an npm install. Usually sets to true.

Frequently Asked Questions
What do Maven properties mean?
Like properties in Ant, Maven properties are value placeholders. Notation $X, where X is the property, can be used to obtain their values anywhere within a POM. Alternatively, plugins may utilize them as default values, such as: In your situation, you declared the properties as a Java version.
How do I configure Maven's system properties?
You only need to set up the Maven Surefire plugin and use the -Dsystemproperty=propertyvalue flag in the command line to supply System Properties to the tests from the command line. Using Maven, run a single test: MessageUtilTest#msg add test -Dmy message=$ mvn test Greetings, Developer!
In a Maven project, where is the application properties file?
The application's properties file must be added to your classpath. Put the file in src/main/resources if you're using Maven or Gradle. Put that in your src folder if you aren't using Maven or any other build tools, and everything should work out.
