In the pom.xml, include the below plugin
<plugin>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-maven-plugin</artifactId>
<executions>
<execution>
<goals>
<goal>repackage</goal>
</goals>
<configuration>
<mainClass>com.baeldung.webjar.WebjarsdemoApplication</mainClass>
</configuration>
</execution>
</executions>
</plugin>
Now we can run our example war with two simple commands:
$ mvn clean package spring-boot:repackage
$ java -DyourSystVar="yourSystVarVal" -jar targetyourbuiltjar.jar
