Module collision betweeen 1.2.0 and 1.2.1 ceylon.test when running tests JVM tests from 1.2.0

[lukedegruchy]

Running 1.2.0 unit tests with either the production 1.2.0 ceylon command or the IDE won't work if any 1.2.1 modules exist in ~/.ceylon/repo. The only way to fix this is to remove all 1.2.1 modules from ~/.ceylon/repo. The only way to fix is to remove all 1.2.1 modules from ~/.ceylon/repo.

This affects both the IDE and the command-line.

I've run ceylon test --verbose=cmr under both cases but unfortunately this offers very little additional insight. For some reason, ceylon attempts to do this, with very little context:

Debug:  Trying repository ~/.ceylon/repo 
Debug:   -> Found at /com/redhat/ceylon/testjvm/1.2.1/com.redhat.ceylon.testjvm-1.2.1.car 

This is the unit test:

import ceylon.test {
    test,
    assertTrue
}

test
void testMe() { assertTrue(true); }

This is the error I see when running the unit test from the IDE:

This doesn't seem to be the case for other modules, as I was able to run a ceylon function having imported both ceylon.collection and ceylon.html and both were correctly resolved to 1.2.0 and the function ran both in the command line and IDE.

[lukedegruchy]

As @jvasileff observed, it seems a lot of modules in 1.2.1 fully or partially identify themselves as "1.2.0" which may be the root cause of this issue.

[jvasileff]

After deleting repo and rebuilding the latest from github, I have:

$ find ~/.ceylon/repo/ -name 1.2.0
/Users/jvasileff/.ceylon/repo//ceylon/bootstrap/1.2.0
/Users/jvasileff/.ceylon/repo//ceylon/language/1.2.0
/Users/jvasileff/.ceylon/repo//ceylon/runtime/1.2.0
/Users/jvasileff/.ceylon/repo//com/redhat/ceylon/common/1.2.0
/Users/jvasileff/.ceylon/repo//com/redhat/ceylon/compiler/java/1.2.0
/Users/jvasileff/.ceylon/repo//com/redhat/ceylon/compiler/js/1.2.0
/Users/jvasileff/.ceylon/repo//com/redhat/ceylon/model/1.2.0
/Users/jvasileff/.ceylon/repo//com/redhat/ceylon/module-resolver/1.2.0
/Users/jvasileff/.ceylon/repo//com/redhat/ceylon/typechecker/1.2.0

Edit: the commands used for this build were:

pushd ceylon-dist && ant clean-all dist sdk eclipse && popd &&
pushd ceylon.language && ant doc && popd &&
true

[lukedegruchy]

Confirmed @jvasileff's observations.

[lukedegruchy]

So I guess the solution to this bug is to ensure the above modules are built as 1.2.1 instead of 1.2.0?

[gavinking]

@lukedegruchy @jvasileff try now.

I'm getting the same error reported by @lukedegruchy on gitter:

As I post this, at some point during the dist compilation process, running tests on the production command-line results in this error. I get the exact same error running tests in the IDE. Once again, deleting ~/.ceylon/repo fixes the issue.

This time I even get issues running JS tests as well. In the command-line I get an error. In the IDE the test takes forever to complete eventually resulting in an error. Again, this is with the production 1.2.0 tools.

Is it fixed now, guys?
