In my [previous post](https://bnd.discourse.group/t/when-it-is-not-a-bundle/59) I showed how to use a non-OSGi JAR. A question was what the purpose of this?

In OSGi you can wrap bundles very easily by including the _whole bundle_ in one fell swoop.

```
-includeresource \
       @${repo;org.apache.mina:mina-core}

```

The `@` function takes a file path and _unrolls_ the JAR in the bundle. I.e. it copies all the entries in that JAR in the bundle you’re bundle. Afterwards it will calculate imports and exports. The `${repo}` macro takes a Bundle Symbolic Name and an optional version and provides the file path.

Great! Wrapping and including bundles since years. But there are always new gems - `$repo` macro inside bnd🤩  
Thx for sharing!
