productBuild.xml generateFeature generates features in random order [message #315618]

Using 3.3M6 pde headless build, I'm having a problem running my build
off the .product definition. My product consists of two different
features, and one must be built before the other.

In the manifest editor I can set the order exactly as needed, but in the
generated feature.xml file in org.eclipse.pde.build.container.feature I
get two different results at random.

Here's the example. 'ca.application.feature' has a dependency on
'ca.core.feature'. Both are in the .product definition and
ca.core.feature is first.

Most times the generated feature is correct. One one host though, I
sometimes get the following which won't compile because the first two
entries are in the wrong order.

Is there no guarantee about the order in which the features in a
..product file will be built? It seemed like a recent feature to allow
you to change the order of features in the product editor so I'm
surprised the build doesn't respect this.

<?xml version="1.0" encoding="UTF-8"?>
<feature id="org.eclipse.pde.build.container.feature" version="1.0.0">
<includes id="ca.application.feature" version="0.0.0"/>
<includes id="ca.core.feature" version="0.0.0"/>
<includes id="org.eclipse.equinox.executable" version="0.0.0"/>
</feature>

The problem is that the class that is generating the container feature is using
a HashSet to collect features. It should instead use something that preserves
order.

Thanks Andrew. I'll keep an eye on that.
