Hi,
I’ve been testing ComponentSelection with 2.2-20140831220010+0000, and it
mostly works, except I don’t get all the candidates that I’d expect to get.
I'd like to be able to select a version of a dependency that was built from
a specific branch. Following a suggestion from Adam, by using the new
ivy-publish plugin, I put some informationin the ivy.xml about the current
branch, and the list of other branches that were available during build:
<info organisation="com.prezi.test.target" module="boxfish-test-target"
branch="master" revision="1.0-3-g1761154" status="integration" publication=
"20140901194902">
<ns:branches xmlns:ns="http://prezi.com/gradle/boxfish";
>master,test-branch</ns:branches>
</info>
I set up a test project, and published a few versions of it from two
different branches, trying to simulate how things would work in real life.
Here are the versions in the order they were published:
- 1.0-8-gf0590b3 from test-branch
- 1.0-3-g1761154 from master
- 1.0-9-g14ae9b9 from test-branch
- 1.0-4-g4b991e5 from master
- 1.0-10-g5ee4b9a from test-branch
I created another project that depends on version "1.+" of my test project.
To can track which versions are tried as candidates, I added this to the
build:
configuration.getResolutionStrategy().getComponentSelection().all(new
RuleAction<ComponentSelection>() {
@Override
public List<Class<?>> getInputTypes() {
return Arrays.<Class<?>> asList(IvyModuleDescriptor.class);
}
@Override
public void execute(ComponentSelection subject, List<?> inputs) {
IvyModuleDescriptor ivyDescriptor = (IvyModuleDescriptor) inputs.get(0);
* logger.info <http://logger.info>("Branch is {}",
ivyDescriptor.getBranch());*
for (Map.Entry<QName, String> entry :
ivyDescriptor.getExtraInfo().asMap().entrySet()) {
* logger.info <http://logger.info>("{} = {}", entry.getKey(),
entry.getValue());*
}
* subject.reject("Because we can");*
}
});
After running `gradle build` I expected to see all of the versions of my
test project printed, but I only got a few of them:

After this I published 1.0-13-g3b3374a from master, and now only that
single version is tried as candidate:

How does Gradle decide which versions to offer as candidates for a certain
dependency?
