how to include static resource from a dependency in spring boot fat jar at the time of build - spring-boot

Question

I have a spring boot application whose UI separately is built and added as a dependency to my application. Now I want to unpack the dependency and add to the resource folder of the spring boot application at the time of build so that it becomes a part of fat jar. Could someone guide me as to how this can be done with spring-boot-maven-plugin.
note: the project is using maven for build
<build>
<plugins>
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-dependency-plugin</artifactId>
<version>2.2</version>
<executions>
<execution>
<id>nflow-explorer</id>
<phase>package</phase>
<goals>
<goal>unpack-dependencies</goal>
</goals>
<configuration>
<includeGroupIds>io.nflow</includeGroupIds>
<includeArtifactIds>nflow-explorer</includeArtifactIds>
<outputDirectory>
${project.build.directory}/resources/main/static/explorer
<!-- or: ${project.basedir}/wherever/you/want/it -->
</outputDirectory>
<overWriteIfNewer>true</overWriteIfNewer>
</configuration>
</execution>
</executions>
</plugin>
<plugin>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-maven-plugin</artifactId>

Answer 1

You don't have to unpack the JAR.
Simply use the Maven Resource Plugin http://maven.apache.org/plugins/maven-resources-plugin/index.html
You can specify directories to include like this:
<project>
...
<build>
...
<resources>
<resource>
<directory>[your folder here]</directory>
</resource>
</resources>
...
</build>
...
</project>
