| − | Until Eclipse mars, the Java Reverse Engineering have been available in the extra plugins of Papyrus. Since Eclipse neon, they are now in a separate Papyrus component, called Papyrus software designer.
| + | = Page has moved to [https://gitlab.eclipse.org/eclipse/papyrus/org.eclipse.papyrus-designer/-/wikis/reverse/java-reverse gitlab] = |
| − | The Java reverse tools allows Java files or packages to be reverse-engineered into a Papyrus class diagram.
| + | |
| − | | + | |
| − | == Installation Instructions== | + | |
| − | Java Reverse Engineering is available as a Papyrus extra plugin.
| + | |
| − | | + | |
| − | You can install it by using the Papyrus update site corresponding to your Papyrus version.
| + | |
| − | Current Papyrus update site can be found in the following page :
| + | |
| − | *http://www.eclipse.org/papyrus/download.html
| + | |
| − | Take the update site corresponding to your Eclipse version.
| + | |
| − | | + | |
| − | Example :
| + | |
| − | *For latest mars version, use:
| + | |
| − | **http://download.eclipse.org/modeling/mdt/papyrus/updates/releases/mars
| + | |
| − | | + | |
| − | *For neon use:
| + | |
| − | **http://download.eclipse.org/modeling/mdt/papyrus/updates/nightly/neon or
| + | |
| − | **http://download.eclipse.org/modeling/mdt/papyrus/updates/releases/neon
| + | |
| − | **with the additional designer update-site: http://download.eclipse.org/modeling/mdt/papyrus/components/designer/
| + | |
| − | | + | |
| − | Please note that the JavaReverse feature is currently not available for neon, it can only be found in the designer git (https://git.eclipse.org/r/papyrus/org.eclipse.papyrus-designer)
| + | |
| − | | + | |
| − | Then :
| + | |
| − | *Unselect 'Group item by category'
| + | |
| − | *Select ' Papyrus Java Reverse (Incubation)'
| + | |
| − | *Finish
| + | |

| − | == How to use Reverse ==
| + | |
| − | === Using Command ===
| + | |
| − | ==== Reverse-engineer a Java class ====
| + | |
| − | A Java class can be reverse-engineered into a Papyrus class diagram:
| + | |
| − | *open the class diagram,
| + | |
| − | *select a Java package from a project
| + | |
| − | * click the Reverse button [[File:ReverseButton.jpg]]
| + | |
| − | | + | |
| − | A UML class is created in Model Explorer. You can now add it into your diagram.
| + | |
| − | Note that all associated classes have also been added to the model.
| + | |
| − | | + | |
| − | ==== Reverse-engineer a package ==== | + | |
| − | A Java package (and all classes included) can be reverse-engineered into a Papyrus class diagram:
| + | |
| − | *open the class diagram,
| + | |
| − | *select a Java package from a project,
| + | |
| − | *click the Reverse button [[File:ReverseButton.jpg]]
| + | |
| − | | + | |
| − | Packages and classes have been created in Model Explorer. Your can now add them to your diagram.
| + | |
| − | Note that all associated classes have also been added to the model.
| + | |
| − | | + | |
| − | ==== Reverse-engineering settings ====
| + | |
| − | By default, a package named "generated" is created for reverse-engineering. You can choose another package name on the options menu.
| + | |
| − | | + | |
| − | [[Image:JavaReverseOptionsMenu.jpg]]
| + | |
| − | | + | |
| − | This options menu allows to:
| + | |
| − | * change the default package of the reverse-engineering,
| + | |
| − | * add or remove search path. The reverse generator search existing UML classes and regenerate them.
| + | |
| − | * add or remove creation path. The reverse generator search on existing Java classes to generate a UML class. Useful for creating Java imports (e.g.: String, Integer).
| + | |
| − | | + | |
| − | === Using Drag & Drop ===
| + | |
| − | You can reverse-engineer a class or a package by just dragging & dropping it on a Papyrus diagram:
| + | |
| − | * Drag one or more classes and/or packages,
| + | |
| − | * Drop the selection into an open diagram.
| + | |
| − | | + | |
| − | [[Image:JavaReverseDragAndDrop.png]]
| + | |
| − | | + | |
| − | A settings dialog is opened. You can modify settings (please see Reverse settings).
| + | |
| − | When you're reverse-engineering via the drag & drop method, you can also choose to display model, packages, and classes / interfaces / enumerations into the Papyrus diagram. To enable display, just click into the check-boxes:
| + | |
| − | | + | |
| − | [[Image:JavaReverseDnDPopUp.png]]
| + | |
| − | | + | |
| − | When you click on the ''OK'' button, your components are displayed in the Papyrus diagram. Note: while all selected components are reversed-engineered, only components which are in selection, but not in the Papyrus diagram are displayed.

| − | == Change default reverse-engineering settings ==
| + | |
| − | The Java code reverse-engineering plugin allows you to change default settings on eclipse preferences:
| + | |
| − | *Open ''Eclipse Preferences'',
| + | |
| − | *Search for the ''Papyrus'' section,
| + | |
| − | *Choose ''Java Code Reverse'' sub-section
| + | |
| − | | + | |
| − | In this preferences page, you can change:
| + | |
| − | *default search path values,
| + | |
| − | *default creation path values.
| + | |
| − | Note that there are default values; if you have changed these values for a project, your changes are saved, and default values are not used.
