yeah,I can install through Eclipse Installer. But for some reason, I need to use json2model in Sirius, so I find that it can't install in Sirius.

You'll need to install Sirius manually through the Help -> Install New Software menu and the https://download.eclipse.org/releases/2023-12 update site as shown below.

it seems I can't install Obeo Designer Community 11.8?

[kolovos]

I'm not familiar with Obeo Designer Community I'm afraid.

[kolovos]

@Haochi1222 I've been able to install Epsilon 2.5 on top of Obeo Designer Community using the following steps:

• Start with a clean instance of Obeo Designer Community 11.8
• Install XSD - XML Schma Definition SDK from https://download.eclipse.org/modeling/emf/emf/builds/release/2.26
• In the Preferences of Obeo Designer Community, go to Install/Update -> Available Software Sites and untick the Eclipse Repository item
• Install Epsilon from http://download.eclipse.org/epsilon/updates/2.5/ excluding the following features
  • Epsilon Sirius Integration
  • Epsilon UML Integration
  • Epsilon CDO Integration

[Haochi1222]

Thank you so much for your detailed response to my question! But when I try the 3rd step, it comes the same error as before , now I'm trying to use both epsilon and obeo Designer to work. I sincerely appreciate the time and effort you took to help me.

[kolovos]

You're right. I've updated the instructions above and it should work now.

[Haochi1222]
