CloverETL 4.2.0 Milestone

CloverETL 4.2 aims at greatly improving developer productivity. We have redesigned the internals of how Designer connects to Server projects so that you can put any project under version control now.

About this release: This is a milestone, many features are under development and might see some changes in the final version. You have a chance to provide feedback on our forum. We appreciate your valuable comments!

New features in 4.2.0-M1


Version control (Git, SVN, ...) now functions with Server projects

Designer now mirrors connected remote Server projects on your local disk, allowing you to put the local copy under version control.

With this you can have remote Server projects directly under version control, you no longer need to keep a versioned local copy of the Server sandbox separately.

Version control operations such as pull, push, commit, merge, etc. work directly with the files in the local copy of the project, so you can use any standard version control tool, including built-in Eclipse plugins for Git and SVN. Designer then transparently synchronizes all changes to the Server sandbox.


Remote Server files available locally

As an effect of the previous feature, you can open and save files originating from a Server sandbox with any tool you need.

CloverETL - remote files locally

Convert projects between local and Server

You can easily deploy a project to Server from your workspace by using Convert To Server Project shortcut. Conversely, you can disconnect a Server project to keep just the local copy or connect and sync it with another Server sandbox.

CloverETL - convert to server project

Source editor Syntax highlighting

The Source tab in the main editor now supports syntax highlighting.

CloverETL - source syntax hightlight

Draw edge from input

You can now draw new edge from an input port to create a new upstream component. Just click an input port, drag to a blank area and then use the Add Component dialog to create the component.

Detailed list of improvements and fixes


Productivity / Version Control for Server Projects [ See All | Hide All ]

Placeholders for large files in Designer New Feature CLO-7899 4.2.0-M1
Large files (over 10MB by default) are not automatically synchronized to the local copy. You can download the files manually or change the threshold in Preferences > CloverETL
Resolving Conflicts between local and server copy New Feature CLO-7836 4.2.0-M1
When Designer synchronizes with Server, you can manually resolve conflicts between incoming and local changes.
Ignore files in server project synchronization New Feature CLO-7604 4.2.0-M1
Unify various clover project natures Improvement CLO-7741 4.2.0-M1
Convert local project to server project (and back) New Feature CLO-8290 4.2.0-M1
In Designer, you can now easily convert a local project to a Server one and vice versa. No need to create new sandbox and then export/copy the files.
Handling of connection outages Improvement CLO-7613 CLO-8207 4.2.0-M1
When working with with Server projects in Designer, connection problems do not affect the synchronization process. Designer will queue the changes until you're back online. Also, Designer reconnects automatically.
Graph header (.grf/.jbf XML files) is now not modified when not needed Improvement CLO-8192 4.2.0-M1
This caused inconveniences when someone resaved a graph without making any changes, yet it appeared as modified in version control, because Designer would change the header in the XML source.
