[MASSEMBLY-856] Ability to overwrite existing files

**[Kamal Mettananda](https://issues.apache.org/jira/secure/ViewProfile.jspa?name=lkamal)** opened **[MASSEMBLY-856](https://issues.apache.org/jira/browse/MASSEMBLY-856?redirect=false)** and commented

This is a request to add \ element to \ in assembly file.

Currently, it is not possible to overwrite the already existing files inside the expected archive with new files.

e.g.:
Expectation of below assembly file is to have the conf.properties file in dir2 after the zip file is generated.

```xml

dist

zip

false



dir1
release



dir2
release
true

```

Start with the assembly descriptor's and handling, using the example in this issue to reproduce the archive contents. The work is done when a later fileSet with true places dir2/conf.properties in the release directory instead of retaining dir1/conf.properties.
