I have a pure Maven project with one OSGi bundle. The project has a` bnd.bnd` and a `app.bndrun` file.  
The JAR is created incrementally including the corresponding OSGi headers.

I want to install and start this bundle with the _Bnd Native Launcher_ in karaf. The `app.bndrun` looks like this:

```auto
-runpath: biz.aQute.remote.launcher

-runremote: debug;\
	shell = -1; \
	jdb = 5005; \
	host = localhost; \
	agent = 29998; \
	timeout = 30000

-runee: JavaSE-1.8

-runproperties: gosh.args=--noshutdown

-runtrace: true

-runbundles: \
	karaf-test

```

When I start the launcher, the bundle is installed and started in karaf.

Whenever I change the Java code, the JAR is automatically regenerated. Unfortunately, the bundle will not restart.

I suspect the problem is because the _BuildListeners_ are not being notified. The _BndtooldBuilder_ does this, but this builder is not active in an enroute workspace (maven).

Is there a solution how to aotomatically restart the bundle with the Bnd Native Launcher?

If desired, I can publish an exmaple workspace on github.

You don’t mention how you are _launching_. That would help us understand the connection between the launcher and builders.

right-click on the posted `.bndrun` file and select `Debug As -> Bnd Native Launcher`

Could you try `Debug As -> Bnd OSGi Run Launcher`?

I have no _OSGi Framework_ inside the workspace. I want to install and start the bundle on a karaf running remote.  
Or do I have to add some OSGi Framework to my workspace?
