I'm new to Spring and Spring Boot, but I'm using it as a template.

我是Spring和Spring Boot的新手,但我正在使用它作為模板。

The Main.java file contains in part the following:

Main.java文件部分包含以下內容:

package com.example;

@Controller
@SpringBootApplication
public class Main {

}

Unfortunately I need to import another class that is called Main, and use it in this class. The other class is in a Jar and I don't really want to recompile it, so I was thinking the best way would be to rename this Main.

不幸的是,我需要導入另一個名為Main的類,並在此類中使用它。另一個類在Jar中,我真的不想重新編譯它,所以我認為最好的方法是重命名這個Main。

However when I do that (renaming it to JavaGettingStarted), the Maven plugin for Spring Boot will fail:

但是,當我這樣做(將其重命名為JavaGettingStarted)時,Spring Boot的Maven插件將失敗:

[ERROR] Failed to execute goal
org.springframework.boot:spring-boot-maven-plugin:2.0.0.RELEASE:repackage
(default) on project java-getting-started: Execution default of goal
org.springframework.boot:spring-boot-maven-plugin:2.0.0.RELEASE:repackage
failed: Unable to find a single main class from the following
candidates [com.example.JavaGettingStarted, com.example.Main] -> [Help

Is Main some sort of default? Can I change it?

Main是某種默認值嗎?我可以改變嗎?
