将 Spring 启动项目导出到可运行的 jar 文件时缺少 Eclipse 启动配置

Question

I have a Spring boot project httpCommonInterface , and have run it in the Eclipse IDE, so I have a launch configuration for it, both in the ide, and on the <workspace>/.metadata/.plugins/org.eclipse.debug.core/.launches folder.(Also I noticed that there is a mismatch between them.)

---

The problem is when I tried to export it to a runnable jar, I can't find that configuration. (They are different for all these three lists!)

---

Without the configuration I can't export that project. How can I fix this?

Answer 1

Only Java Applications launch configurations are shown in the Runnable Jar dialog.

Even if the Spring boot project has been run as a Spring boot application (and a configration file is created, and we can see the spring boot lunch configuration in the ide), we still cannot export it to a runnable jar file.

So the solution is that we firstly run the Spring boot project as a java application , then its launch configuration is listed.

How to run the Spring boo project as a java application:

1. right click on the project;

2. run as -> run configration ;

3. on the left part of the window, choose one instance of Java Application (if none, new one);

   4. config the run configration , like the Project and Main Class in the Project tab.
