ModelDemo.java Compile Error

[刘乔森]

I get the following error when compiling as per` javac -cp lib/model.jar demo/ModelDemo.java`:

I did not modify the file and compiled it exactly as described in the comment at the beginning of ModelDemo.java.


UPPAAL Version: 5.0.0
Ubuntu: 22.04
Java Version: openjdk-17

Hi,

Thank you for the report.

There were lots of changes and concurrency fixes in the API and we forgot to update the ModelDemo, I am sorry.

I attach the fixed ModelDemo example which works with Uppaal-5.1.0-beta5:

https://people.cs.aau.dk/~marius/ModelDemo-for-UPPAAL-5.1.0-beta5.zip

Please unpack it into your uppaal-5.1.0-beta5/demo directory.

The archive has `run` script which should take care of compiling and launching the example.

On Windows the script assumes that UPPAAL_HOME environment variable is set to path where Uppaal is installed.

Best regards,
Marius
