如何將預先存在的Java項目導入Eclipse並啓動並運行？

關於重複參考的評論：爲什麼在標記爲重複的問題之前的幾年被問到時，這會被標記爲重複？我也相信問題，細節和反應比引用的問題好得多。如何將預先存在的Java項目導入Eclipse並啓動並運行？

我一直是一個C++程序員很長一段時間，但我是新來的Java和新的Eclipse。我想使用touch graph "Graph Layout" code可視化我正在使用的一些數據。

該代碼被組織這樣的：

./com 
./com/touchgraph 
./com/touchgraph/graphlayout 
./com/touchgraph/graphlayout/Edge.java 
./com/touchgraph/graphlayout/GLPanel.java

如何在Eclipse中添加此項目，並把它編譯和運行快？

在Eclipse中創建一個新的Java項目。這將創建一個src文件夾（包含您的源文件）。
還創建一個lib文件夾（名稱不是那麼重要，但它遵循標準約定）。
將./com/*文件夾複製到/src文件夾中（您可以使用操作系統執行此操作，無需從Eclipse GUI進行任何特殊導入或任何操作）。
複製（即項目本身取決於jar文件）到/lib任何依賴關係（注意，這不應包括TGGL jar - ！由於評論者邁克橋面指出我的老年退休金計劃的誤解後）
複製其他TGGL東西到根項目文件夾（或專用於您需要在最終應用分發許可其他文件夾）
早在Eclipse中，選擇你在步驟1中創建的項目，然後點擊F5鍵（這會刷新實際內容的Eclipse文件夾樹視圖。
/src文件夾的內容將自動進行編譯（將類文件放置在Eclipse爲您創建項目時爲您生成的/ bin文件中）。 如果你有依賴項（你不在你當前的項目中，但爲了完整性我將在這裏包含它），編譯將最初失敗，因爲你缺少項目類路徑中的依賴關係jar files。
最後，在Eclipse中打開文件夾/lib，right click每個需要jar file，選擇Build Path->Add到構建路徑。
