java.lang.NoSuchMethodError com.fasterxml.jackson.core.JsonParseException using dropbox v2 core api java

Question

I have a program that is already working a couple of years but it is not working anymore now due to a jackson.core error and I can not figure out why it is thrown.

Chunck of code that throws the error ( last line ):

//Build inputstream
if(yearDirCheck == true && monthDirCheck == true){
//The folder already exists, upload the file directly
try (InputStream in = new FileInputStream(docname)) {
FileMetadata metadata = client.files().uploadBuilder(path + "/" + jaar + "/"+ maand +"/" + docname)
    .uploadAndFinish(in);
} 
catch (IOException ex) {
    Logger.getLogger(maakPDF.class.getName()).log(Level.SEVERE, null, ex);
}  
mail.verzendOverurenKaart(Technician, client.sharing().createSharedLinkWithSettings(path + "/" + jaar + "/"+ maand +"/" + docname).getUrl()); 

}

The error i get:

Exception in thread "AWT-EventQueue-0" java.lang.NoSuchMethodError: 'void com.fasterxml.jackson.core.JsonParseException.<init>(com.fasterxml.jackson.core.JsonParser, java.lang.String)'

I am using the jackson-core-2.6.1 library and thus the dorpbox v2 core api in java. Not using maven or gradle or anything.

Answer 1

If you check your libs, you have two jackson-core dependencies. 2.6.1 and 2.7.4. Usually this kind of exception is associated with dependencies conflicts, so removing one should fix it.
