It would be really helpful for others to help you if you could provide additional details such as what is not working for you, what exactly are you trying to do after installing the designer?

Hi ‌,

You are right, the link to the build has been removed during the migration.

We are facing the issue.

Maybe you could grad the source code directly from github : Releases · Activiti/Activiti-Designer · GitHub.

Prior to this, i have changed following file /Activiti-Designer-master/org.activiti.designer.parent/pom.xml and change line from

<graphiti-site>http://download.eclipse.org/graphiti/updates/0.11.4</graphiti-site> to

<graphiti-site> http://archive.eclipse.org/graphiti/updates/0.11.4</graphiti-site>

As, location for graphiti site has been changed at eclipse.

After more investigation, i found reason was due to machine environment properties.

<environment>
<os>macosx</os>
<ws>cocoa</ws>
<arch>x86_64</arch>
</environment>

I have changed it to following , and it works.

<environment>
<os>win32</os>
<ws>win32</ws>
<arch>x86</arch>
</environment>

If you have the build, could be an idea to share it here. 🙂
Many thanks.
