java - Java eBay SDK - 无法初始化类 com.ebay.sdk.SdkAPIInterfaceServiceLocator

Question

我正在使用 eBay SDK for Java 进行 API 调用以返回订单。这在过去有效，但最近我收到以下错误：

Exception in thread "Thread-4" java.lang.NoClassDefFoundError: Could not initialize class com.ebay.sdk.SdkAPIInterfaceServiceLocator
at com.ebay.sdk.ApiCall.executeByApiName(Unknown Source)
at com.ebay.sdk.ApiCall.execute(Unknown Source)
at com.ebay.sdk.call.GetOrdersCall.getOrders(GetOrdersCall.java:169)

我这样称呼它：

GetOrdersCall call = new GetOrdersCall(context);        
    call.setCreateTimeFrom(createTimeFrom);
    
    call.setCreateTimeTo(Calendar.getInstance());
    
    PaginationType pagination = new PaginationType();
    pagination.setEntriesPerPage(pageSize);
    pagination.setPageNumber(pageNumber);
    
    call.setPagination(pagination);     
    
    ordersResult = call.getOrders();

我的 Classpath 中有所有必需的 JAR。有任何想法吗？
