Im trying to import a library called ConfigUpdater, the problem is that even if there aren't problems (i defined it in the pom.xml and made no errors), when i load the plugin it give me the error: java.lang.NoClassDefFoundError

Thats the full error:

You need to shade it

#

or use the libraries feature if it's in maven central

median kelp Apr 26, 2023, 5:48 PM

#

i tried, maybe im doing it wrong

tall ferry Apr 26, 2023, 5:48 PM

i added this to the pom.xml to shade, but no changes

tall ferry Apr 26, 2023, 5:48 PM

#

https://maven.apache.org/plugins/maven-shade-plugin/examples/class-relocation.html

#

Also make sure to use the correct jar since it will create multiple

#

The shaded pattern should be inside your package

median kelp Apr 26, 2023, 5:50 PM

#

tall ferry Also make sure to use the correct jar since it will create multiple

how can i choose witch jar to use?

tall ferry Apr 26, 2023, 5:50 PM

#

?

#

The one you use is the one you put in the plugins folder

#

So only put the jar that doesn't end with -shaded or -original

median kelp Apr 26, 2023, 5:51 PM

#

aahh yeahyeah

#

im using eclipse, i could share the package with eclipse right?

tall ferry Apr 26, 2023, 5:58 PM

#

Don't use eclipses package name for your plugin

median kelp Apr 26, 2023, 6:02 PM

#

is it right?

tall ferry Apr 26, 2023, 6:07 PM

#

median kelp is it right?

I'd use a sub package for the dependency

#

other than that, try it and see

median kelp Apr 26, 2023, 6:13 PM

#

again the same error

tall ferry Apr 26, 2023, 6:17 PM

#

Could you send the jar

median kelp Apr 26, 2023, 6:25 PM

#

idk what to try anymore

tall ferry Apr 26, 2023, 6:33 PM

#

You're not even using maven to compile ._.

#

Use maven and it should work fine

median kelp Apr 26, 2023, 6:49 PM

#

but the file that i compile with maven doesnt have the plugin.yml

tall ferry Apr 26, 2023, 6:53 PM

#

Did you put it in the resources folder?

median kelp Apr 26, 2023, 7:32 PM

#

what?

#

its the first time that im using maven

tall ferry Apr 26, 2023, 7:32 PM

#

I can tell

median kelp Apr 26, 2023, 7:33 PM

#

do i have to change something in the build part?

tall ferry Apr 26, 2023, 7:36 PM

#

src/main/resources

#

put the plugin.yml there

median kelp Apr 26, 2023, 8:00 PM

#
