How can I run Mauve (GUI) on Linux? I can use progressiveMauve on the terminal. How can I even open a java executable?

Thank you

Try java -jar Mauve.jar instead of ./Mauve.jar.

Mauve also may require Java 7/8.

I tried java -jar Mauve.jar but same error. My Java is:

openjdk version "17.0.9" 2023-10-17
OpenJDK Runtime Environment (Red_Hat-17.0.9.0.9-4) (build 17.0.9+9)
OpenJDK 64-Bit Server VM (Red_Hat-17.0.9.0.9-4) (build 17.0.9+9, mixed mode, sharing)

You likely need a much older version of Java. 7 or 8.

Also, since Mauve is no longer maintained, what is a contemporary alternative? Tx

I see, so Mauve GUI is a legacy software that needs an old version of Java no longer maintained. Tx
