Subject [jira] [Commented] (KAFKA-1813) Build fails for scala 2.9.2
Date Sat, 13 Dec 2014 02:23:13 GMT

Guozhang Wang commented on KAFKA-1813:
--------------------------------------

Thanks Anatoly.

When I ran the tests / builds before checking in KAFKA-1650 I did not see either this issue
or KAFKA-1815, which is a bit wired. Will do some local testing again.

> Currently, in trunk, the 2.9.2 build fails with the following error:
> MirrorMaker.scala:507 overloaded method value commitOffsets with alternatives:
>   (isAutoCommit: Boolean,topicPartitionOffsets: scala.collection.immutable.Map[kafka.common.TopicAndPartition,kafka.common.OffsetAndMetadata])Unit
<and>
>   (isAutoCommit: Boolean)Unit <and>
>   => Unit
>  cannot be applied to (isAutoCommit: Boolean, scala.collection.immutable.Map[kafka.common.TopicAndPartition,kafka.common.OffsetAndMetadata])
>         connector.commitOffsets(isAutoCommit = false, offsetsToCommit)
> It looks like the 2.9.2 compiler cannot resolve an overloaded method when mixing named
and ordered parameters.
> I ran into this when I cloned the repo and ran ./gradlew test.
