<triggerfile>

Trigger file does not work for me, it always fire up full build even if the files in trigger file didn't change
version 0.26, execution gulp.

                <execution>
                    <id>gulp</id>
                    <goals>
                        <goal>gulp</goal>
                    </goals>
                    <!-- <phase>generate-resources</phase> -->
                    <configuration>
                        <srcdir>${basedir}</srcdir>
                        <arguments>--no-color ${gulp.wiredep} </arguments>
                        <triggerfiles>
                            <triggerfile>gulpfile.js</triggerfile>
                            <triggerfile>bower.json</triggerfile>
                        </triggerfiles>
                    </configuration>
                </execution>

I've the same behavior on v1.6

The problem is here https://github.com/eirslett/frontend-maven-plugin/blob/4f21ed9a467fe407f849356957e2b9c27e5eb972/frontend-maven-plugin/src/main/java/com/github/eirslett/maven/plugins/frontend/mojo/MojoUtils.java#L83-100
Where if you have set triggerfile and not set scrdir the return of https://github.com/eirslett/frontend-maven-plugin/blob/4f21ed9a467fe407f849356957e2b9c27e5eb972/frontend-maven-plugin/src/main/java/com/github/eirslett/maven/plugins/frontend/mojo/MojoUtils.java#L91-93
should return triggerfiles == null;.
This just in case srcdir is not set the plugin should think there is not a modification, otherwise it will always fire the execution.

My workaround:

<execution>
	<id>gulp-build</id>
	<goals>
		<goal>gulp</goal>
	</goals>
	<phase>generate-resources</phase>
	<configuration>
		<arguments>build ${frontend.deploy}</arguments>
		<triggerfiles>
			<triggerfile>Gulpfile.js</triggerfile>
			<triggerfile>package.json</triggerfile>
		</triggerfiles>
		<srcdir>src/main/unused</srcdir>
	</configuration>
</execution>
<execution>
	<id>gulp-styles</id>
	<goals>
		<goal>gulp</goal>
	</goals>
	<phase>generate-resources</phase>
	<configuration>
		<arguments>styles ${frontend.deploy}</arguments>
		<srcdir>src/main/frontend/css/</srcdir>
	</configuration>
</execution>
<execution>
	<id>gulp-js</id>
	<goals>
		<goal>gulp</goal>
	</goals>
	<phase>generate-resources</phase>
	<configuration>

</execution>
