scala - Intellij IDEA don't recognize Play 2.0 features -

i checked out project github, run sbt gen-idea , opened project in idea. 1 of project modules uses play 2.0 framework.

but idea don't recognize symbols specific play!. i.e. following error: cannot resolve symbol index in following statement views.html.index.

same errors on other specific play! framework features, example same error on routes variable.

p.s. have installed play 2.0, scala, sbt plugins , configured play 2.0 framework root directory (in project settings - play configuration)

personally, don't use play addon intellij. it's far quicker , reliable use command-line in order compile/generate different elements including famous *.template.scala, @ origin of cannot resolve symbol index notification.

all have run command-line based on app's root folder: play compile. of course, not rebuild project intellij, otherwize you'd erase generated class files command-line. when dealing non-managed resources (like templates), make cmd+f9 compile.

making sure output compilation intellij configured map same folder app's target folder (what sbt gen-idea (although use playthen idea with-sources=yes) auto-configures).

then intellij project not complain more views.html.index unresolved.

of course, if want benefit intellij ide, make sure have installed last play 2.x plugin.

alternatively, create custom runcommand in intellij in order take in account sbt compilation.
