------------------------------------
Summary: ApplicationBundler will overwrite dependencies with
identical names
Key: TWILL-182
URL: https://issues.apache.org/jira/browse/TWILL-182
Project: Apache Twill
Issue Type: Bug
Components: core
Affects Versions: 0.7.0-incubating
Reporter: Martin Serrano
If two jars obtained from *different* classpath locations have the same name
but different contents, one will overwrite the other. The dependency code
correctly finds the jars (uses the full path in the HashSet which accumulates
the deps) but when the bundle is created the jars are written to {{/lib}} under
their name. This results in one overwriting the other.
While this is not a likely occurrence, it occurs for us in our development
environment because our published jar names are built up from their project
hierarchy. For example the model project for our sdk is in {{.../sdk/model}}
and will be on the classpath as {{.../sdk/model.jar}} and published as
{{sdk-model.jar}}.
In practice however this could occur with any jar name and would be more likely
over time.
The {{ApplicationBundler}} could detect this over time and re-write the name
with some part of the path or suffix to ensure the name is unique.
