Java 可執行 Jar 文件

Question

我正在嘗試從 eclipse 制作一個可執行的 jar 文件（使用 MySQL 作為數據庫）。

如何制作可執行的jar文件？

我做了一個，但它顯示了一些警告並且不起作用。 我收到了一個很長的警告列表。 這是警告：

Answer 1

“它顯示了一些警告但不起作用”請記住，如果您不提供有關遇到的錯誤的詳細信息，我們將無法為您提供太多幫助： http : //imgur.com/jacoj

Eclipse 可能會警告您已經創建了帶有警告的可執行 jar 文件。 這只是意味着您的課程有警告（黃色！）。 這並不意味着生成的 jar 文件將不起作用。

Answer 2

1. 右鍵單擊需要導出為 jar 的項目
2. 從列表中選擇“導出”選項
3. 從新的彈出窗口中，選擇“Runnable jar file”
4. 點擊“下一步”按鈕
5. 在下一個窗口中，為您的 jar 和啟動配置命名（具有 main 方法的類）
6. 為所需的庫選擇適當的選項，然后單擊完成按鈕

Answer 3

文件->導出->可運行的 JAR 文件

然后你可以選擇，天氣你想要在 jar 中復制 jars 或只是 extact 它們

Answer 4

當您有一個 Java 類的內容被完全注釋掉時，就會發生這種情況。 但是，創建的 jar 應該最有可能工作。

Answer 5

警告很好，這不會導致可執行 jar 出現問題。

通過解壓 jar 文件檢查<Your JAR name>.jar\\META-INF\\MANIFEST.MF並找到Main-Class: <your entry point class with main method> 。

如果這個Main-Class不存在，那么在創建 jar 時就會出現問題。

確保您遵循正確的步驟。 請查看本指南以創建 jar作為參考。

注意：您可以手動編輯MANIFEST.MF
