创建可执行jar - 无法找到或加载主类

Question

我已经创建了一个Java Swing应用程序，现在我想将其导出为可执行jar文件。我在eclipse中创建了应用程序，它具有以下结构：

其中文件夹mysqlconnector也包含jar文件。我在制作名为manifest的{​​{1}}文件时做了三件不同的努力：

1。

manifest.mf

2。

 Main-Class: bin.main.MainClass

3。

 Main-Class: src.main.MainClass

我将 Main-Class: MainClass 放在文件夹manifest.mf中，并在终端中提供了以下命令：

seo

创建jar -cvfm seo.jar manifest.mf * 后，命令：

jar

给我以下输出：

jar -tvf seo.jar

但是当我从终端0 Wed Mar 15 09:13:26 EET 2017 META-INF/ 101 Wed Mar 15 09:13:26 EET 2017 META-INF/MANIFEST.MF 0 Fri Dec 09 14:00:06 EET 2016 arial-unicode-ms/ 23275812 Fri Dec 09 14:00:06 EET 2016 arial-unicode-ms/ARIALUNI.TTF 2426 Fri Dec 09 14:00:06 EET 2016 arial-unicode-ms/arial-unicode-ms.png 98 Fri Dec 09 14:00:06 EET 2016 arial-unicode-ms/myfontsfree.txt 23275812 Fri Dec 09 13:59:58 EET 2016 ARIALUNI.TTF 0 Mon Mar 13 11:35:16 EET 2017 bin/ 0 Mon Mar 13 09:03:32 EET 2017 bin/gui/ 5702 Mon Mar 13 09:03:32 EET 2017 bin/gui/GuiFrame.class 73666 Mon Mar 13 09:03:24 EET 2017 bin/gui/img.png 0 Wed Mar 15 09:10:16 EET 2017 bin/main/ 1961 Mon Mar 13 09:03:32 EET 2017 bin/main/ReadProperties.class 1007 Mon Mar 13 11:30:24 EET 2017 bin/main/MainClass.class 0 Mon Mar 13 11:29:12 EET 2017 bin/main/resources/ 157 Mon Mar 13 11:29:12 EET 2017 bin/main/resources/connectionprops.properties 0 Mon Mar 13 09:03:32 EET 2017 bin/listeners/ 5395 Mon Mar 13 09:03:32 EET 2017 bin/listeners/RegisterIdListener.class 5065 Mon Mar 13 09:03:32 EET 2017 bin/listeners/PayIdListener.class 5081 Mon Mar 13 09:03:32 EET 2017 bin/listeners/StarToBirdListener.class 5095 Mon Mar 13 09:03:32 EET 2017 bin/listeners/DeleteStarListener.class 648 Mon Mar 13 09:03:32 EET 2017 bin/listeners/GoBackListener.class 2707 Mon Mar 13 09:03:32 EET 2017 bin/listeners/DeleteListener.class 73666 Mon Mar 13 09:03:24 EET 2017 bin/listeners/img.png 2612 Mon Mar 13 09:03:32 EET 2017 bin/listeners/NewYearListener.class 6023 Mon Mar 13 09:03:32 EET 2017 bin/listeners/PassListener.class 6710 Mon Mar 13 09:03:32 EET 2017 bin/listeners/AllListener.class 3523 Mon Mar 13 09:03:32 EET 2017 bin/listeners/PdfListener.class 7011 Mon Mar 13 09:03:32 EET 2017 bin/listeners/NewStarListener.class 6620 Mon Mar 13 09:03:32 EET 2017 bin/listeners/PaidIdListener.class 2644 Mon Mar 13 09:03:32 EET 2017 bin/listeners/PayListener.class 6737 Mon Mar 13 09:03:32 EET 2017 bin/listeners/GotIdListener.class 6671 Mon Mar 13 09:03:32 EET 2017 bin/listeners/ToBirdsListener.class 5474 Mon Mar 13 09:03:32 EET 2017 bin/listeners/ReportsListener.class 5385 Mon Mar 13 09:03:32 EET 2017 bin/listeners/NewListener.class 2892 Mon Mar 13 09:03:32 EET 2017 bin/listeners/RegisterListener.class 0 Mon Mar 13 11:35:16 EET 2017 bin/META-INF/ 53 Mon Mar 13 11:35:16 EET 2017 bin/META-INF/MANIFEST.MF 73666 Mon Mar 13 09:03:24 EET 2017 bin/img.png 0 Mon Mar 13 11:35:18 EET 2017 classes/ 0 Mon Mar 13 11:35:18 EET 2017 classes/artifacts/ 0 Mon Mar 13 11:35:18 EET 2017 classes/artifacts/seo_jar/ 3406481 Mon Mar 13 11:35:18 EET 2017 classes/artifacts/seo_jar/seo.jar 157 Sun Jan 22 18:26:06 EET 2017 connectionprops.properties 2148384 Mon Nov 14 17:22:10 EET 2016 itextpdf-5.5.4.jar 31 Mon Mar 13 09:27:02 EET 2017 manifest.mf 0 Thu Dec 08 14:32:48 EET 2016 mysqlconnector/ 960374 Fri Oct 17 08:05:36 EEST 2014 mysqlconnector/mysql-connector-java-5.1.34-bin.jar 1358 Fri Mar 10 09:57:22 EET 2017 seo.iml 0 Wed Mar 15 09:11:32 EET 2017 src/ 0 Wed Feb 01 15:01:04 EET 2017 src/gui/ 73666 Fri Dec 09 13:56:32 EET 2016 src/gui/img.png 5617 Wed Feb 01 12:15:26 EET 2017 src/gui/GuiFrame.java 0 Wed Mar 15 09:08:44 EET 2017 src/main/ 601 Fri Mar 03 19:11:24 EET 2017 src/main/MainClass.java~ 1315 Sun Jan 22 18:30:54 EET 2017 src/main/ReadProperties.java 1060 Mon Mar 13 11:30:24 EET 2017 src/main/MainClass.java 0 Mon Mar 13 11:27:02 EET 2017 src/main/resources/ 157 Sun Jan 22 18:26:06 EET 2017 src/main/resources/connectionprops.properties 48 Wed Mar 15 09:08:32 EET 2017 src/main/MANIFEST.MF 0 Fri Mar 10 10:55:40 EET 2017 src/listeners/ 4761 Wed Feb 01 15:33:12 EET 2017 src/listeners/DeleteStarListener.java 5330 Fri Mar 10 10:55:38 EET 2017 src/listeners/PaidIdListener.java 5268 Fri Mar 10 10:55:40 EET 2017 src/listeners/GotIdListener.java 5233 Fri Mar 10 10:55:40 EET 2017 src/listeners/ToBirdsListener.java 5217 Wed Feb 01 15:33:52 EET 2017 src/listeners/RegisterIdListener.java 405 Wed Feb 01 15:32:56 EET 2017 src/listeners/GoBackListener.java 2361 Wed Feb 01 12:13:34 EET 2017 src/listeners/PdfListener.java 5761 Fri Mar 10 10:55:40 EET 2017 src/listeners/AllListener.java 4700 Wed Feb 01 15:33:30 EET 2017 src/listeners/PayIdListener.java 5165 Fri Mar 10 10:15:20 EET 2017 src/listeners/NewListener.java 4717 Wed Feb 01 15:33:18 EET 2017 src/listeners/StarToBirdListener.java 5222 Fri Mar 10 10:12:06 EET 2017 src/listeners/ReportsListener.java 5922 Fri Mar 10 10:17:32 EET 2017 src/listeners/PassListener.java 73666 Fri Dec 09 13:56:32 EET 2016 src/listeners/img.png 2333 Wed Feb 01 12:13:34 EET 2017 src/listeners/NewYearListener.java 6827 Wed Feb 01 15:33:36 EET 2017 src/listeners/NewStarListener.java 2008 Fri Mar 10 10:14:06 EET 2017 src/listeners/PayListener.java 2162 Fri Mar 10 10:15:20 EET 2017 src/listeners/RegisterListener.java 1982 Fri Mar 10 10:15:20 EET 2017 src/listeners/DeleteListener.java 73666 Fri Dec 09 13:56:32 EET 2016 src/img.png 执行时，我收到错误：

或

  

错误：无法找到或加载主类src.main.MainClass

或

  

错误：无法找到或加载主类MainClass

根据我在清单文件中指定的主类。

我做错了什么？我应该改变项目结构中的某些内容吗？如何创建可执行文件java -jar seo.jar并成功执行它？
