This pageI'm trying to start Fighting ICE using Eclipse while referring to, but the following error occurs and I can't start it.

Error occurred during initialization of boot layer
java.lang.module.FindException: Unable to derive module descriptor for C: \ pleiades \ workspace \ FightingICEv4.50 \ lib \ py4j0.10.4.jar
Caused by: java.lang.IllegalArgumentException: py4j0.10.4: Invalid module name: '10' is not a Java identifier

I also import the library as specified in the reference URL, and even if I search by the error code, there is no solution that comes to my mind, so I will ask you a question.

Eclipse is downloaded from Pleades and is Version: 2020-09 (4.17.0).
Settings such as JDK have not been tampered with and are the same as when downloaded.

Please answer somebody.
