Hola, estoy haciendo mi primer curso de Java.
Al querer ejecutar Hello World me sale esto:

Error occurred during initialization of boot layer
java.lang.module.FindException: Error reading module: /home/homero/eclipse-workspace/JavaBasics/bin
Caused by: java.lang.module.InvalidModuleDescriptorException: HelloWorld.class found in top-level directory (unnamed package not allowed in module)
