Sling IDE tooling 1.0

The 1.0 release will be a release with minimal release which will allow users to sync content between their IDE and the repository.


Our IDE tooling should not focus on a single IDE and the naming should reflect that. Possible names

  • Sling Developer Tools
  • Sling IDE

Platform support

We will aim to support Eclipse and IntelliJ with a first 1.0 release.

High-level architecture

Core services

The core services will be IDE-agnostic and aim to support all platforms. As such, they will be constrained to not use specific APIs. Eclipse mandates that all I/O operations be done using its resource layer.

Server control

The server control service will handle communication with a Sling Launchpad instance, including

  • connecting ( validating credentials )
  • starting and stopping ( only possible for JAR-based launchpad )

Transport API

Contains the APIs needed to connect to Sling launchpad and import/export content.

Transport implementations

VLT transport

File vault is in process of being donated to to ASF and is a good candidate for a transport implementation.


  1. Mature application and library
  2. Already used to import, export and sync content


  1. Works at JCR, not at resource level

Lightweight HTTP-based transport

The current implementation is based on the Sling DefaultGetServlet and DefaultPostServlet and is another candidate for a transport implementation.


  1. Works at resource level


  1. Does not work reliably if the DefaultGetServlet is not active for a certain resource

Eclipse implementation

High-level pieces

  • WST Server - we will use the Eclipse web tools platform to provide UI elements ( server definition, start/stop actions, module deployments )
  • Content module - we will define a content module which uses the transport API to sync content from the workspace into the repository. The mechanism is controlled by the WST server definitions
  • Transport API bridge - links between the core transport APIs and the Eclipse build/resource APIs

We will inherit some code from the current implementation, and need to work out a way to export content from the repository into the workspace with the proposed UI flow.

Intellij Implementation

High-level pieces

  • Application server - uses the IntelliJ application server framework
  • Transport API bridge - links between the core transport APIs and the IntelliJ build/resource APIs
  • No labels
