Get Java Code Generator to work [message #1793291] Fri, 03 August 2018 07:48 Go to next message

Hi there,

I'm a Papyrus beginner and want to test to generate Java Code from an UML State Machine. However, I don't get it to work. Not even for class diagrams.

I tried:

1. Install Eclipse Photon and add Papyrus through Photon Update site
2. Install Java Code generator as documented here https://wiki.eclipse.org/Java_Code_Generation
3. Check that Java Code generation preferences are available in the Eclipse preferences.
3. Create initial Class Diagram with one class
4. Open Context menu as described in the Wiki
→ The context menu does not show the "Designer" entry and no sub-menus for code-generation

Other approach:

1. Install the Papyrus 4.0.0 RCP
→ Code generator seems not to be available in the vanilla Papyrus RCP
2. Install Java Code generator as described in the Wiki
→ Still, the context menu does not show the "Designer" entry and no sub-menus for code-generation

How do I get it to work? Will eventually State Machines generate Code also? Or are only Class Diagrams supported?

Cheers,
Hauke

Dear Hauke,

we started to create a new release (1.1.0) of SW designer recently which includes a dedicated build for photon. While the specific update site for photon should work (see below), the composite update site containing multiple builds lead to bug bug537700 that caused a mixup of plugin versions.

You might try re-installing with the specific photon update-site http://download.eclipse.org/modeling/mdt/papyrus/components/designer/photon. As we will remove it soon (before re-creating a working release), you can also try the nightly update-site of the photon build /org.eclipse.papyrus.designer.p2/target/repository/]https://hudson.eclipse.org/papyrus/job/papyrus-designer-photon/lastSuccessfulBuild/artifact/releng/org.eclipse.papyrus.designer.p2/target/repository/. Remove all Papyrus related update-sites before re-installing.

Designer supports state-machine code generation for C++, but currently not for Java.

Excellent news about the C++ state machine code generation, Ansgar.
Will this be a full implementation or are parallel state machines still excluded? Is there a list of supported features somewhere?
I'm also interested to hear which versions of C++ are supported.

Thanks,
Steve

State-machine support should be pretty complete (including parallel regions). That does not exclude that there are eventually bugs, but we're done quite a lot of tests from the PSSM (precise semantics of state-machines) test suite.

There is currently no specific support for more recent variants of C++, notably the native threading.
