Could not load plugin when composed into JAR #9

Closed quartzsaber closed 6 years ago

quartzsaber commented 6 years ago

If I load the plugin via FDevTools, it loads. But if I compose it into jar with makeplugin and load that jar instead, nukkit says [CRITICAL] Could not load plugin 'MyPlugin' and provides no further information.

My directory structure:

MyPlugin_src/
├ plugin.yml
└ src/
    └ com/example/myplugin
        └ Main.java

Content of plugin.yml:

name: MyPlugin
main: com.example.myplugin.Main
version: "1.0.0"
api: ["1.0.0"]
author: min050820@gmail.com
description: Keep EXP even after death!

I wonder what's wrong. My plugin works as expected in source format.

I can't find any mistakes,is this [CRITICAL] message send by Nukkit or FDT?

Best Regards, FENGberd

I believe it's from nukkit since I removed FDT when testing the JAR. I'll post the whole log soon.

Here is the whole log from nukkit. Note that I removed FDT to test my plugin. (So FDT not loading is expected.)

Should I go to nukkit issue tracker then?

quartzsaber commented 6 years ago

Okay, now I know what happened. I opened the JAR file, and it contained no class file. At all!

I believe it happens when there are multiple plugins loaded by FDT. When I removed my helloworld plugin (which was also loaded by FDT), /makeplugin correctly made JAR file with class files. Also, I should note that I put multiple classes in one .java file, in case it has something to do with this issue.

Fine,glad to hear you've solved it.
