问使用requestJWTUserToken时出错，只需替换我的帐户信息SDK项目，junit代码

EN

ApiClient apiClient = new ApiClient (BaseUrl);
//String currentDir = System.getProperty("user.dir");

try
{

    // IMPORTANT NOTE:
    // the first time you ask for a JWT access token, you should grant access by making the following call
    // get DocuSign OAuth authorization url:
    //String oauthLoginUrl = apiClient.getJWTUri(IntegratorKey, RedirectURI, OAuthBaseUrl);
    // open DocuSign OAuth authorization url in the browser, login and grant access
    //Desktop.getDesktop().browse(URI.create(oauthLoginUrl));
    // END OF NOTE
    byte[] privateKeyBytes = null;
    try
    {
        privateKeyBytes = Files.readAllBytes (Paths.get (privateKeyFullPath) );
    }
    catch (IOException ioExcp)
    {
        Assert.assertEquals (null, ioExcp);
    }
    if (privateKeyBytes == null)
    {
        return;
    }
    java.util.List<String> scopes = new ArrayList<String>();
    scopes.add (OAuth.Scope_SIGNATURE);
    scopes.add (OAuth.Scope_IMPERSONATION);
    OAuth.OAuthToken oAuthToken = apiClient.requestJWTUserToken (IntegratorKey, UserId, scopes, privateKeyBytes, 3600);
}
