Robbie Gemmell commented on PROTON-499:
---------------------------------------
This wasnt really a circular dependency as such, instead more of an unenforced
ordering requirement. While it could use the artifacts from a previous build
(as its really meant to be able to, for what it thinks are independent modules)
it typically wouldnt be doing so.
The main reason you saw a problem (which admittedly is still quite an
annoyance) is that the 'tests' module depended on the test jar from the
proton-j module, which you explicitly didnt create by only running 'maven
compile'. I have run the build on a number of fresh boxes recently without
issue, the main diference being that the more typical 'maven test' or 'maven
install' commands create the test artifacts for project-j before ever getting
to the 'tests' module ('maven test-compile' might also have worked due to being
in the same reactor build, not sure), which would then pick up the necessary
artifact from the current reactor build. When using 'maven compile' by itself,
it would have either been picking up a previously installed version if you had
recently done that, or instead been hitting the Apache snapshots repository
occasionally to download the nightly build, hence the offline flag making the
difference when your local repo was cleared.

> The maven build depends on the binaries from the output of the prior
> iteration of the build. This is a bit hard to notice because maven seems to
> be downloading snapshot binaries from somewhere. Reproduce with the following
> steps:
> # First ensure legitimate dependencies are downloaded:
> mvn compile
> # now blow away snapshots that should not be needed for a clean build
> rm -rf ~/.m2/repository/org/apache/qpid/
> # now run an offline build
> mvn -o compile
> You should see this failure:
> [ERROR] Failed to execute goal
> org.apache.maven.plugins:maven-remote-resources-plugin:1.4:process (default)
> on project proton-tests: Failed to resolve dependencies for one or more
> projects in the reactor. Reason: Missing:
