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

Question

我有一个已经工作了几年的程序，但现在因为一个jackson.core错误而不能工作了，我想不通为什么会抛出这个错误。

抛出该错误的代码块(最后一行):

//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()); 

}

我得到的错误是：我使用的是jackson-core-2.6.1库和java中的dorpbox v2 core api。

我使用的是jackson-core -2.6.1库，也就是java中的dorpbox v2 core api。没有使用maven或gradle或任何东西。

如果你检查你的libs，你有两个 jackson-core 的依赖关系。2.6.1和2.7.4.通常这种异常与依赖冲突有关，所以去掉一个应该可以解决。
