I have met an error message like thatI don't know where that message throws from and is there anyone can tell me how to fix it.Thanks everyone,
What version of LT are you using? The stand-alone one or the LibreOffice add-on?
I am using the standard-alone version.
The latest one, i.e. 3.7? Could you check what's in your libs folder inside the LT directory? How do you start LT, by clicking the languagetool.jar file I guess?
Yes, I start LT by clicking the languagetool.jar file. I think the cause of error is Lucene library. LT used Lucene 5.5.3 and the lastest version of Lucene is 6.5.0.
Yes, but we provide the proper library for that (libs/lucene-backward-codecs.jar), that's why I asked for the contents of your libs folder. With LT 3.7, I cannot reproduce your issue, sorry.
Ok, don't bother it. You helped so lots. You answered a lot of my questions. I'm very appreciative.
