Dropbox找不到资源trusted-certs.jks

Question

我试着在bukkit插件中正常使用dropbox java api，但由于某些原因，它就是不起作用。以下是dropbox部分的代码：

public DbxClient client;
final String APP_KEY = "<REDACTED>";
final String APP_SECRET = "<REDACTED>";

DbxAppInfo appInfo = new DbxAppInfo(APP_KEY, APP_SECRET);

DbxRequestConfig config = new DbxRequestConfig(
        "JavaTutorial/1.0", Locale.getDefault().toString());
DbxWebAuthNoRedirect webAuth = new DbxWebAuthNoRedirect(config, appInfo);
String authorizeUrl = webAuth.start();

public void geturl(Player p){
    p.sendMessage(authorizeUrl);
}

public void authorize(String code){
    try{
        DbxAuthFinish authFinish = webAuth.finish(code);
        String accessToken = authFinish.accessToken;
        client = new DbxClient(config, accessToken);
    }
    catch(DbxException e){}

}

public void upload(String fullpath){
    try {
        File inputFile = new File(fullpath);
        FileInputStream inputStream = new FileInputStream(inputFile);
        DbxEntry.File uploadedFile = client.uploadFile(fullpath,
                DbxWriteMode.add(), inputFile.length(), inputStream);
        inputStream.close();
    }
    catch(DbxException| IOException e){}

不管怎样，geturl运行得很好，它返回一个url，我点击它，然后复制我得到的代码。然后，我继续以该代码作为参数运行authorize，并得到以下错误：

显然，重要的部分是它所说的原因，我如何解决这个问题？

Answer 1

当我尝试使用webAuth.finish(代码)从Dropbox服务器获取访问代码时，我遇到了类似的问题。这个库需要"JKS“密钥库，这在android平台上是不存在的。
