如何制作可运行的.jar文件？
[英]How to make a runnable .jar file?
问题描述
for school i have to make a game, together with 2 classmates. 
为了上学，我必须和两名同学一起做游戏。 our group had to make something in Java, a language we never used before. 我们的小组不得不用Java编写某种东西，这是我们以前从未使用过的语言。 we got ourselfs a little game now, but we can't seem to get it into a working .jar file nor a runnable jar. 我们现在有一个小游戏，但似乎无法将其放入工作的.jar文件或可运行的jar中。 We use eclipse, but the .jar file created through export => jar file doesn't work. 我们使用eclipse，但是通过export => jar文件创建的.jar文件不起作用。 it doesn't do anything. 它什么也没做。 (manifest file is totally empty) the runnable jar file is even worse, it says there is no main class selected, but when i try to set 'Main.class' as main class, then it's not in the list. （清单文件完全为空），可运行的jar文件甚至更糟，它说没有选择主类，但是当我尝试将'Main.class'设置为主类时，它不在列表中。 (at advanced options for creating a runnable jar in Eclipse) i tried through cmd too, but then it couldn't find a manifest attribute... any help? （在Eclipse中创建可运行jar的高级选项）我也尝试了cmd，但是后来找不到清单属性...有什么帮助吗？ my maps: -Smash'em All -.settings - bin -data (all my images and such) -Smash (all the .class files) -java.policy.applet - src -data (some old pictures, not the same as in the other data map) -Smash (all the .java files) - .classpath - .project 我的地图：-Smash'em全部-.settings-bin -data（所有我的图像等）-Smash（所有.class文件）-java.policy.applet-src -data（一些旧图片，与在另一个数据图中）-粉碎（所有.java文件）-.classpath-.project
any idea how to make a runnable jar? 任何想法如何制作一个可运行的罐子？ and if i want to implement it in HTML, do i need a runnable or just a .jar file? 如果我想用HTML来实现它，我需要一个可运行文件还是仅一个.jar文件？ EDIT: my lay-out doesn't seem saved? 编辑：我的布局似乎没有保存？ :( sorry, is my first post ever herer :( :(对不起，这是我的第一篇文章herer :(

如果要使用“ java -jar”运行，则需要在JAR清单中指定主类。

要使用java -jar命令运行jar，或双击您需要指示要运行的主类的jar，可以通过在jar的META-INF / Manifest.MF中添加Main-Class来进行操作 。可以看到如何设置主类

To add to Césars' comment, have you tried: 要添加到Césars的评论中，您是否尝试过：
jar cvf YourApplication.jar *.class
From " Java How to Program " : 从“ Java How to Program ”中：
That should jar up your classes which creates in the current directory a JAR file named YourApplication.jar containing the applet's .class files.
As per one of your questions, you asked "if i want to implement it in HTML, do i need a runnable or just a .jar file". 根据您的问题之一，您问“如果要在HTML中实现它，我需要一个可运行文件还是仅一个.jar文件”。 No, you can just run the class file, if you want. 不，您可以根据需要运行类文件。

<body>
<applet code = "YourApplication.class" width = "300" height = "45">
</applet>
</body>
</html>
