我正在尝试从 eclipse 制作一个可执行的 jar 文件（使用 MySQL 作为数据库）。

如何制作可执行的 jar 文件？

我做了一个，但它显示了一些警告并且不起作用。我收到了一份很长的警告清单。这是警告：

“它显示了一些警告并且不起作用”请记住，如果您不提供有关您遇到的错误的详细信息，我们将无法为您提供太多帮助：http: //imgur.com/jacoj

Eclipse 可能会警告您已创建可执行 jar 文件并带有警告。这只是意味着您的课程有警告（黄色！）。这并不意味着生成的 jar 文件将不起作用。

  1. 右键单击需要导出为 jar 的项目
  2. 从列表中选择“导出”选项
  3. 从新的弹出窗口中，选择“可运行的 jar 文件”
  4. 单击“下一步”按钮
  5. 在下一个窗口中为您的 jar 和启动配置（具有 main 方法的类）命名
  6. 为所需的库选择适当的选项，然后单击完成按钮

文件->导出->可运行的 JAR 文件

然后你可以选择，天气你想在 jar 中复制 jar 或者只是提取它们

当您有一个其内容被完全注释掉的 java 类时，就会发生这种情况。但是，创建的 jar 应该最有可能工作。

警告很好，这不会导致可执行 jar 出现问题。

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

如果这Main-Class不存在，那么在创建 jar 时出现了问题。

确保您遵循正确的步骤。请查看本指南以创建 jar作为参考。

注意：您可以手动编辑MANIFEST.MF
