[ERROR] Failed to execute goal
org.apache.sling:sling-maven-plugin:3.0.3-SNAPSHOT:uninstall (bundle-uninstall)
on project example-pom: Uninstall from http://localhost:50972/system/console/
failed, cause: status code: 404, reason phrase: Not Found -> [Help 1]
{code}
The reason is that the installation happens asynchronously in a background
thread in
https://github.com/apache/felix-dev/blob/8e35c940a95c91f3fee09c537dbaf9665e5d027e/webconsole/src/main/java/org/apache/felix/webconsole/internal/core/BundlesServlet.java#L1726,
so there is a race condition if the uninstall is triggered before the
installation in the background thread is finished.
Also the documentation in currently incorrectly states:
{quote}
Felix Web Console
The plugin by default places an HTTP POST request to the Felix Web Console.
This will achieve both upload and installation of the bundle in one request
synchronously.
{quote}
In fact this is an asynchronous operation.
