Palladio Bench 5.0 Product Builds (Recommended)

Eclipse 2020-12 based All-In-One products to run Palladio and its core features out of the box are provided under Palladio Bench download site. Just download the appropriate Zip file for your system and extract and run it like you would run a normal Eclipse installation. In case you need additional Palladio features you can use the preconfigured "Install new software..." dialog with the Palladio Bench Update site selected.

If you are running recent versions of MacOS, you might experience a message saying that Palladio is broken. Most probably, this traces back to a security feature prohibiting the execution of non-signed, downloaded software. Please try to run xattr -rd com.apple.quarantine Eclipse.app to fix this issue.

Please don't use the built-in ZIP functionality of Windows OS - it is known to cause problems with Eclipse ZIP files. Instead, try 7zip or alternatives.

To install the Palladio tooling via Eclipse Marketplace, visit the Palladio 5.0 marketplace entry and drag the Install button to a running Eclipse 2020-12 Modeling Tools instance.
