Question

我正在Spring Boot和嵌入式服务器中迈出第一步。我发现这个In28Minutes Tutorial非常容易理解。现在我不得不尝试生成一个工件SNAPSHOT.jar文件，我将其导入到我的RCP项目中。运行maven clean install没有帮助。谁能帮我吗？ Hier是一些信息：

Spring Boot框架
Spring Boot默认使用Tomcat作为嵌入式服务器容器

Hier是控制台输出

Answer 1

所以我会尝试假设，你没有创建主类，在某个地方，你应该有类似的东西：

[INFO] BUILD FAILURE
[INFO] ------------------------------------------------------------------------
[INFO] Total time: 2.410 s
[INFO] Finished at: 2018-06-10T18:26:06+03:00
[INFO] Final Memory: 32M/1266M
[INFO] ------------------------------------------------------------------------
[ERROR] Failed to execute goal org.springframework.boot:spring-boot-maven-plugin:2.0.2.RELEASE:repackage (default) on project demo: Execution default of goal org.springframework.boot:spring-boot-maven-plugin:2.0.2.RELEASE:repackage failed: Unable to find main class -> [Help 1]

为了使这个工作添加主类到你的src / main / java文件夹

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;

@SpringBootApplication
public class HelloApplication {

    public static void main(String[] args) {
        SpringApplication.run(HelloApplication.class, args);
    }
}

在日志末尾执行mvn clean install的结果应该是：

[INFO] ------------------------------------------------------------------------
[INFO] BUILD SUCCESS
[INFO] ------------------------------------------------------------------------
[INFO] Total time: 3.043 s
[INFO] Finished at: 2018-06-10T18:29:38+03:00
[INFO] Final Memory: 40M/1004M
[INFO] ------------------------------------------------------------------------

在目标中，您将获得demo-0.0.1-SNAPSHOT.jar

希望这会有所帮助。

Answer 2

我欠你们一个道歉。我搞砸了。我有两个测试包，如下图所示。所以第一个是正确的设置，但第二个是没有。这就是为什么我有一次测试失败我无法解释的原因。现在，我删除了包，Maven运行槽。尽管如此，我还是要感谢你们帮助我解决一个不是第一个问题的问题:-)

maven clean install不会生成工件SNAPSHOT.jar
