Questions about the compiler

Using Scala 2.9.1. I have a simple java bean class with an annotation e.g.

@Foo

public class FooBean {

...

}

I have some scala code that calls a method on FooBean.

The Foo annotation class is in a jar that is not accessible to the scala compiler, but FooBean is available in the compiler's classpath. When the scala compiler tries to compile my scala code, it gives me a "Missing dependency" error:

scala> new FooBean

error: error while loading FooBean, Missing dependency 'class package.to.Foo', required by /home/raman/test/jars/foobean.jar(FooBean.class)

<console>:8: error: FooBean does not have a constructor

new FooBean

This seems very similar to https://issues.scala-lang.org/browse/SI-1135, which is marked as Fixed.

Has SI-1135 been broken in Scala 2.9.1?

Also, on a side note, I noticed that the subsequent times the compilation is executed, the "Missing dependency" error is no longer shown (which can be confusing):

scala> new FooBean

<console>:8: error: FooBean does not have a constructor

new FooBean

I believe this was fixed once and for all as SI-5343 [1] in commit 1684baef [2]. This is not available yet in a released version of Scala, but is available in 2.10.0-M1.

My google-fu failed me this time. Thank you!

Apparently your problem will still occur -- these changes go in the right direction, but aren't sufficient. Can you raise an new issue?

Ok, trying to do that, but unable to login to JIRA:

You do not have a permission to log in. If you think this is incorrect, please contact your JIRA administrators.

And the "JIRA administrators" page is not configured either.

I verified a similar problem does indeed still occur on 2.10.0.M1. I created: https://issues.scala-lang.org/browse/SI-5420.
