Question

我正在尝试从eclipse创建一个可执行的jar文件（使用MySQL作为数据库）。

如何制作可执行jar文件？

我做了一个，但它显示了一些警告而不起作用。我得到一个很长的警告清单。这是警告：

Answer 1

＆＃34;它显示一些警告而不是工作＆＃34; 请注意，如果您没有提供有关遇到的错误的详细信息，我们将无法为您提供更多帮助：http://imgur.com/jacoj

Eclipse可能会警告您已经创建了带有警告的可执行jar文件。这只意味着你的班级有警告（黄色！）。它并不意味着生产的jar文件不会起作用。

Answer 2

右键单击需要导出为jar
从列表中选择“导出”选项
从新弹出窗口中选择“Runnable jar file”
点击“下一步”按钮
在下一个窗口中，给出jar的名称和启动配置（带主方法的类）
为所需的库选择适当的选项，然后单击“完成”按钮

Answer 3

文件 - ＆gt;导出 - ＆gt;可运行的JAR文件

然后你可以选择，天气你想在罐子里复制罐子或只是接触它们

Answer 4

当您有一个Java类，其内容被完全注释掉时，可能会发生这种情况。但是，创建的jar很可能可以工作。

Answer 5

警告很好，这不会导致可执行jar的问题。

通过取消归档jar文件检查<Your JAR name>.jar\META-INF\MANIFEST.MF并找到Main-Class: <your entry point class with main method>。

如果没有Main-Class，那么在创建jar时会出现问题。

确保遵循正确的步骤。请将此guide for creating jar作为参考。

注意：您可以手动修改MANIFEST.MF
