java.lang.NoSuchMethodError


(gregh) #1

Hello

I am getting this exception:

Caused by: java.lang.NoSuchMethodError: org.apache.commons.lang.ObjectUtils.clone(Ljava/lang/Object;)Ljava/lang/Object;

After upgrading to version 3.5. There is a clone method on org.apache.commons.lang3.ObjectUtils.

Cheers

Could you post the complete stack trace? When exactly does this happen?


(gregh) #3

Sorry, checking on my dependencies it was using commons-lang-2.4.jar and I think your classes uses commons-lang-2.6.jar. Everyone has now upgraded to lang3 but language tool plus one other are still using the old lan2. Is it possible to switch to lang3 here as version 2 is end of life now.


(Daniel Naber) #4

I've just done that (here). As one of our (unmaintained, it seems) dependencies is still on commons-lang 2.6, that still needs to be in the classpath, though.


(gregh) #5

OK great, checking on my dependencies it is only on the langualetool-core, possibly I exclude the jar that uses the 2.6 version? Which jar uses 2.6?


(Daniel Naber) #6

Actually lang-zh is still on 2.4, languagetool-dev (which shouldn't be relevant at runtime) is still at 2.6.


(gregh) #7

If its -zh, as I only use -en it should be gone. :smile:

org.languagetool
language-en

I do get a polish jar from morfologik-speller ??

morfologik-polish-2.0.0.jar

Cheers

I cannot reproduce that, could you check (and maybe post) the complete output of mvn dependency:report?

Maybe there was a bug in Morfologik 2.1.0 (used by LT 3.5), but it should be fixed in git, as I cannot reproduce this. We're using Morfologik 2.1.2 now.


(gregh) #11

I just specify 3.5 and Morfologik is only used for me by language tool so not sure why I only get 2.1.0.


(gregh) #12

If I only want to spell check do you know what jars I actually need?


(Daniel Naber) #13

No sorry, you'll have to try.
