How do I prevent Maven's spring-boot plugin from copying static resources to target?

Question

I recently updated the OS on my laptop (Linux Mint 17.1 => 17.3) and now when I run my project with

mvn spring-boot:run

static resources are copied to the target folder, essentially caching them. Thus I have to completely bounce the server to see changes made to the static resources reflected in the browser.

This was not the case before I updated my laptop. I have also found that it is exclusive to this project, other spring-boot projects are not affected.

I also cannot get static resources to update when running in eclipse, both in normal and debug mode.

Some additional information:

Java version: 1.7
Spring-boot version: 1.3.2
spring-boot maven plugin version: 1.3.2
Maven version: 3.3.9

Any ideas?

Explicitly setting the addResources config item in the spring-boot maven plugin seems to fix this. The plugin declaration in your pom file will look like this:

<plugin>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-maven-plugin</artifactId>
    <configuration>
        <addResources>true</addResources>
    </configuration>        
    <executions>
        <execution>
            <goals>
                <goal>repackage</goal>
            </goals>
        </execution>
    </executions>
</plugin>

Interestingly, adding the spring-boot-devtools dependency doesn't not fix this, despite the documentation specifically mentioning it would do the same thing as the addResources config item.
