在Jenkins中部署Spring Boot战争

I have a Jenkins job for deploy Spring-Boot war.

When I launch my job I have this error:

Why ?

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]

The spring-boot-maven-plugin allows you to package executable jar or war archives and run an application(automatically). So, you will need specify the Main class for your application. See guideline here.

So, in short, you can add main class to your Manifest by:

1. Add directly to Manifest.MF

2. Specify Optional Parameters for spring-boot-maven-plugin in your pom.xml. Below is example:

    <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>
