Regarding the Apache repository ( http://repository.apache.org/snapshots ): it doesn't seem to help because https://repository.apache.org/content/groups/snapshots/org/apache/flex/flex-tool-api/1.0.0-SNAPSHOT/ looks quite blank and https://repository.apache.org/content/repositories/snapshots/org/apache/flex/flex-tool-api/ doesn't have version 1.0.0-SNAPSHOT... :)
Here's the more detailed stack on the error message: Barna -- View this message in context: http://apache-flex-users.2333346.n4.nabble.com/Missing-4-12-1-20140427-dependency-information-warnings-in-build-tp9907p9918.html Sent from the Apache Flex Users mailing list archive at Nabble.com.
