Hello all the doc in https://docs.oracle.com/javase/9/docs/specs/jar/jar.html lists for Main-Class entry in jars: "attribute defined for stand-alone applications: This attribute is used by stand-alone applications that are bundled into executable jar files which can be invoked by the java runtime directly by running "java -jar x.jar". apparently it means that you should not create a modular jar with a manifest template containing a Main-Class entry (apparently if you run the app with command "java -module-path dir -m com.thing.app" with the generated com.thing.app.jar the main class will not be found : you get a message saying you've got no Mainclass atrribute) but if you generate the jar with a manifest template with no Main-Class entry and instead use the --main-class option then the main class will be found. funnily the MANIFEST-MF will then have the same Main-Class entry! so what is the difference? (btw I suggest more docs that differentiate clearly what to do 1) with non-modular jars 2) with modular jars .. ... or is it I can't read the doc properly?)
thanks Bear
