build failed with ''Unable to find a javac compiler' on ubuntu2

[Robbie Gemmell <ro...@gmail.com>]

Hi all,

In addition to the issue I emailed about the other day wherby I am
seeing JAVA_HOME related failures with a matrix project when the
configurations run on ubuntu1, the project has also failed on ubuntu2
due to being unable to find javac because it is using a JRE (output
below).

The project continues to work OK when the configurations execute on
ubuntu3, but I'd rather not have to restrict it to just ubuntu3, could
someone take a look? The project is:
https://builds.apache.org/view/M-R/view/Qpid/job/qpid-java-test-matrix/

Thanks,
Robbie

Perhaps JAVA_HOME does not point to the JDK.

You, sir, are a genius...or perhaps its more likely in this case that
I am an idiot :S

That sounds far too logical not to be the answer, and after updating
it accordingly and forcing a build it is seemingly working away OK on
ubuntu2 so far. I imagine its going to complete just fine, and work on
ubuntu1 now too. It amazes me I missed that; I blame ubuntu3 for
throwing me off the trail :)

Thanks,
Robbie

I'm not very familiar with matrix builds, but it looks like your
builds are not choosing a JDK to use. Perhaps you need to add an axis
that sets the JDK version.
