Can't create a runnable jar file via Eclipse
提问by Yonatan Nir
I made a Java project with Eclipse. The project has a public static void main(String[] args)method in it.
When I try to export it to a runnable jar, the launch configuration does not include the project I created so I can't create the jar for the project. Any ideas why?
我用 Eclipse 做了一个 Java 项目。该项目中有一个public static void main(String[] args)方法。当我尝试将其导出到可运行的 jar 时，启动配置不包括我创建的项目，因此我无法为该项目创建 jar。任何想法为什么？

Try creating a new launch configuration from scratch:
尝试从头开始创建一个新的启动配置：
Run->Run Configurations...- Right click "Java Application" in the list on the left and select
New - On the right enter a descriptive name.
- In the Main tab browse for your project and search for and select the appropriate main class.
- Close the dialog.
Run->Run Configurations...- 右键单击左侧列表中的“Java 应用程序”并选择
New - 在右侧输入描述性名称。
- 在 Main 选项卡中，浏览您的项目并搜索并选择适当的主类。
- 关闭对话框。
Now try exporting your runnable JAR again using that run configuration.
现在尝试使用该运行配置再次导出您的可运行 JAR。

Either run the project once to automatically create a run configuration or go into the project options and create one manually.
要么运行项目一次以自动创建运行配置，要么进入项目选项并手动创建一个。

One more answer, in hope it will help some one:
I had a situation where the configuration did appear in the Run -> Run Configurationslist,
but did not appearon the list of the Ruannable JAR export wizard.
It was cured only after I closed and re-launched Eclipse.
还有一个答案，希望对大家有所帮助：
我遇到过这样一种情况，配置确实出现在Run -> Run Configurations列表中，
但没有出现在 Ruannable JAR 导出向导的列表中。
只有在我关闭并重新启动 Eclipse 后它才被治愈。
