Facet not being included in Jar

[scphantm]

I create a facet "secondSrc" and everything seems fine. But when i do a gradle build i get a jar file that only has the classes from the main sourceset. And, here's my output

:clean
:compileJava
:compileGroovy UP-TO-DATE
:processResources UP-TO-DATE
:classes
:writeManifestProperties
:jar
:assemble
:compileTestJava UP-TO-DATE
:compileTestGroovy UP-TO-DATE
:processTestResources UP-TO-DATE
:testClasses UP-TO-DATE
:test UP-TO-DATE
:compileFunctionalTestJava UP-TO-DATE
:compileFunctionalTestGroovy UP-TO-DATE
:processFunctionalTestResources UP-TO-DATE
:functionalTestClasses UP-TO-DATE
:functionalTest UP-TO-DATE
:compileIntegTestJava UP-TO-DATE
:compileIntegTestGroovy UP-TO-DATE
:processIntegTestResources UP-TO-DATE
:integTestClasses UP-TO-DATE
:integrationTest UP-TO-DATE
:check UP-TO-DATE
:compileSecondSrcJava
:compileSecondSrcGroovy UP-TO-DATE
:processSecondSrcResources UP-TO-DATE
:secondSrcClasses
:build

BUILD SUCCESSFUL

It appears the facet is being executed after the java stuff is executed. This is on gradle 3.0 and 3.1
