Không thể chạy dự án mẫu playn - biên dịch lỗi

Question

Tôi đã cố làm theo hướng dẫn trên trang bắt đầu cho playn và gặp sự cố khi chạy chương trình giới thiệu java đầu tiên. Tôi nhận được các lỗi sau khi nhấp chuột phải và chạy thử Maven. Ngoài ra tôi nhận được rất nhiều sai sót trong vấn đề tab của nhật thực liên quan đến (thất bại trong việc chuyển xxx từ yyy) trong đó xxx là một số file jar và yyy là một gwt hoặc trang web playn

Nhấp chuột phải vào "playn-showcase", sau đó: Run As -> Maven Install

Lần sau bạn muốn khởi chạy mẫu, bạn có thể làm theo các thủ tục hướng dẫn: nhấp chuột

chuột phải vào "playn-showcase-java", sau đó: Run As -> Maven thử nghiệm
