Build process dies dramatically in case of issues when compiling the test-fixtures

[Michael Eichberg]

I.e., if the test fixtures don't compile, the whole process should "just stop" - throwing "dramatic exceptions" is not necessary.

Removing milestone: 0.9.0-M1 (automated comment)

[Simon Leischnig]

It was not meant to be dramatic -- the little I found on failing an sbt task suggested to do so with an exception. Mark O' Harrah suggested this also on http://grokbase.com/t/gg/simple-build-tool/134cjtzkhb/sbt-sbt-fail-build-gracefully

When I changed one compiler.config file in a test fixture to provoke an error, it suppressed the stack trace and just printed out:

(from a clean sbt test invocation)

Am I correct in assuming the above stacktrace in the issue was printed by invoking "last" in the sbt shell? In which context was it produced? One form to read the issue is that the whole sbt build should be aborted. Is this correct? Do you have any suggestions on how to perform the desired "just stopping of the process" behavior? Thanks!

I can't reproduce the issue anymore; when the fixtures don't compile, the error message ist perfectly fine (now?).
