Through Eclipse Mars, the Java Reverse Engineering was available in the Papyrus extra plugins. Since Eclipse Neon, they are now in a separate Papyrus component, called Papyrus software designer.
|
|
|
|
|
The Java reverse tools allow Java files or packages to be reverse-engineered into a Papyrus class diagram.

The Java features of Papyrus are available as part of the http://wiki.eclipse.org/Papyrus_Software_Designer[Papyrus Software Designer] extra feature.
|
|
The reverse engineering capabilities are part of the Java feature of Papyrus SW designer. Java reverse is available, once the Java feature is installed via update site or marketplace. See link:../getting-started
|

|
You can install it by using the Papyrus Software Designer update-site (for Oxygen):
|
|
|
|
|
|
|
|
|
|
* http://download.eclipse.org/modeling/mdt/papyrus/components/designer/
|
|
|
|
|
|
|
|
|
|
Or you can use the nightly build update site for Oxygen (paste following url in eclipse update site):
|
|
|
|
|
|
|
|
|
|
* https://hudson.eclipse.org/papyrus/job/papyrus-designer-photon/lastSuccessfulBuild/artifact/releng/org.eclipse.papyrus.designer.p2/target/repository/
|
|
|
|
|
|
|
|
|
|
Then select "Papyrus Java profile, library and code generation (Incubation)" feature. You need JDT installed (which comes with most Eclipse packages).
