                </executions>
            </plugin>
        </plugins>
    </build>
</project>

Getting below error while executing looks like read property plugin is not generating application.properties inside target folder. Below is the snapshot of my project.

Below pluginExecutor structure will solve your problem.

<pluginExecutor>
<plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-resources-plugin</artifactId>
    <version>3.2.0</version>
</plugin>
<goal>copy-resources</goal>
<configuration>
    <outputDirectory>${project.build.outputDirectory}/${item}/</outputDirectory>
    <resources>
        <resource>
            <directory>${project.basedir}/config/resources/templates</directory>
            <filtering>false</filtering>
            <include>application.properties</include>
        </resource>
    </resources>
</configuration>
