Eclipse的Java項目不能與一些奇怪的錯誤運行

大家好我收到以下錯誤，當我試圖運行一個開源項目，任何想法，以避免這些錯誤，Eclipse的Java項目不能與一些奇怪的錯誤運行

放需要的jar在類路徑 – Sanjeev

你可以在這裏添加您的代碼？除非我們能爲您提供什麼幫助？只有日誌不能提供更多信息。看來你缺少導入jar。 –

底部面板 - > java問題。 – rpax

Unresolved compilation problems

意味着兩件事情可以去錯在Eclipse：

1）src目錄沒有被標記爲源文件夾

轉到項目>屬性> Java構建路徑>來源並添加源文件夾

2）你必須從你的項目，要麼是不存在的項目或不在你的classpath中引用的一些jar文件。

轉到項目>屬性> Java構建路徑>庫和添加的jar 文件（如果你有罐子）

非常感謝我已經按照你的說法添加了它們，但它似乎還沒有解決，你能否看到屏幕截圖。 http://postimg.org/image/vc15wlubx/ – user3653683

我沒有看到任何新帖子 – Hirak

對不起，看到鏈接http://postimg.org/image/arlyo6r4n/和http://postimg.org/image/vc15wlubx/919cab8a/ – user3653683
