部署春季引导战争詹金斯

Question

我有一个Jenkins部署弹簧引导战争的工作。

当我启动我的工作，我有这样的错误：

为什么？

Answer 1

[ERROR] Failed to execute goal org.springframework.boot:spring-boot-maven-plugin:1.3.0.RC1:repackage (default) on project rest-api: 
Execution default of goal org.springframework.boot:spring-boot-maven-plugin:1.3.0.RC1:repackage failed: **Unable to find main class** -> [Help 1] 

spring-boot-maven-plugin允许您打包可执行jar或war档案并运行应用程序（自动）。所以，你需要为你的应用程序指定Main类。 请参阅guideline这里。

因此，简而言之，你可以通过添加主类，以你的清单：

1. 直接加入的Manifest.MF

2. 在你的POM弹簧引导Maven的插件指定Optional Parameters .XML。下面是例子：

   <plugin> 
   <groupId>org.springframework.boot</groupId> 
   <artifactId>spring-boot-maven-plugin</artifactId> 
   <version>1.0.3.BUILD-SNAPSHOT</version> 
   <configuration> 
       <mainClass>com.test.Application</mainClass> 
   
   </configuration> 
   <executions> 
   <execution> 
       <goals> 
        <goal>repackage</goal> 
       </goals> 
   </execution>
