Compilation failing when transitive dependencies exist #480

Closed jvasileff closed 9 years ago

jvasileff commented 9 years ago

With a new project created with ceylon new hello-world, and with the following module.ceylon:

module com.example.helloworld "1.0.0" {
    import ceylon.test "1.1.1";
    // or any other module that has an import
}

I get:

$ ceylon compile-js
ceylon compile-js: null

The error does not appear when the transitive dependencies are explicitly imported:

module com.example.helloworld "1.0.0" {
    import ceylon.collection "1.1.1";
    import ceylon.test "1.1.1";
}
