repro:

git clone git@github.com:cbeams/spring-project.git
git checkout m5-classpath-bug
./gradlew build

notice compilation errors out of the spring-project-aj subproject:

package org.springframework.project.core does not exist

switch back to milestone-3 and notice compilation/building succeds. Nothing has changed in the project dependency configurations, only the upgrade to m5-snapshot from m3. Note that I did try Crebuild and -nodaemon as well to no effect.

$ git checkout 2edd4da3238b7a1a12ae1a96a3809af2fb70c502

By the way, I was trying to upgrade to milestone-5, because it contains the signing plugin documented here: http://gradle.org/releases/1.0-milestone-4/docs/userguide/signing_plugin.html

Unfortunately, I had to find out the hard way that Luke's standalone repository for the signing plugin at https://github.com/alkemist/gradle-signing-plugin is NOT in fact up to date with what's in M5 and what's advertised at the documentation above with regard to the availability of the signPom method. Thus the upgrade in an effort to be able to follow the instructions properly.

Thanks,

C
