Going to talk about Sling IDE Tooling at adaptTo 2014

I’m happy to say that in September I’ll be going back to Berlin for adaptTo 2014 . adaptTo is a conference which gathers developers from the Apache Sling and friends community.

I’m going to talk about the progress that we’ve made the last year with the Sling IDE Tooling and show how quickly you can develop Sling-based applications. Whether you’re working with OSGi bundles, frontend files, backend scripts or unstructured content, we have something to make you more productive.

I hope I’ll see you at adaptTo in Berlin this September.

Apache Sling: viewing bundles by start level

When packaging an Apache Sling application it is useful to see the final list of bundles included in your launchpad grouped by their start levels. This is especially true if the bundle list is configured using sensible defaults, for instance using the default bundle list as a start.

When the launchpad is packaged using the maven-bundle-plugin, the bundles are placed grouped by their start level under target/classes/resources/bundles . The ever-useful tree command allows us to inspect this directory ( I’ve removed some of the bundles to make the output easier to understand )

Although the directories are not ordered numerically – an option which I have not found in my version of the tree command – the output is easy to understand and offers an overview of the start levels and bundles associated with them.
