java - One or more required project facets are missing from the project -


i've imported java-project eclipse , error "one or more required project facets missing project myproject" without further details. project's facet switched on "java".

thats description "problems view":

description=one or more required project facets missing project myproject.  resource=myproject  path=   location=unknown  type=project facet missing marker

how discover facet missing? how eclipse detect such problems? can related else facet? f.e. compilance level or else?

ps i've cleaned project several times.

thanks in advance

you need add @ least spring facet , possibly others depending on features you're using. the eclipse page describes how this.

scala - 'wrong top statement declaration' when using slick in IntelliJ -

i'm porting project scala 2.9 2.10, therefore have use slick instead of scalaquery. i'm using slick 2.1.0 since supports ms access. according this tutorial , upgrade guide changed robs object class , added val robs : why error message wrong top statement declaration , how rid of it? edit: i'm new scala... according this question seems can't put val outside of methods or classes, right? code above directly in packge. right approach slick then? should move code in class or trait? according this changed val robs = tablequery[robs] to object robs extends tablequery(new robs(_)) {} . no warnings or errors anymore. :)
