Running Forge 1.12-14.21.1.2397, 64bit java 8 update 131

 

ForgeGradle and Minecraft are using jopt-simple-5.0.3, but Forge still seems to be using jopt-simple:4.6. This might be causing strange exceptions when calling any method deriving from JOpt.

 

For example:

parser.acceptsAll(Arrays.asList("help", "?"), "Help");

will throw

java.lang.NoSuchMethodError: joptsimple.OptionParser.acceptsAll(Ljava/util/List;)Ljoptsimple/OptionSpecBuilder;

ONLY when running outside the developer environment, otherwise it runs just fine.

 

Edit: just to be clear. I am talking about the dependencies listed in the json file inside the versions folder.

Right, Forgot we have to force the server to have JOpt, because Mojang believes in manually parsing the command line for the dedicated server -.-
