How to package a project with a specified main function in Maven?
In order to specify the main class for Maven packaging, you need to configure the maven-compiler-plugin in the pom.xml file and specify the mainClass property.
Add the following code under the build node:
<plugins>
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-compiler-plugin</artifactId>
<version>3.8.1</version>
<configuration>
<source>1.8</source>
<target>1.8</target>
<encoding>UTF-8</encoding>
<mainClass>com.example.MainClass</mainClass>
</configuration>
</plugin>
</plugins>
Replace com.example.MainClass with the package path and class name of your main class.
Next, when packaging with Maven, execute the following command:
mvn clean package
This will designate the main class as the entry class and generate an executable JAR file.
