Atollic/STM32cubeMX generates code but fails to open project (Java version problem?)
I just installed the latest Atollic package, and the latest STM32cubeMX 4.27.0 plug-in.
Created a cube project, edited the configuration, generated code.
After code generation I clicked Open Project, but it failed:

The newly generated project doesn't show up in the workspace where it was created.
If I add the project manually to the workspace, it does not build.
How can I get past this?
Thanks!
