Question

我有Jenkins部署Spring-Boot war的工作。

当我开始工作时，我有这个错误：

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）。因此，您需要为应用程序指定Main类。请在此处查看guideline。

因此，简而言之，您可以通过以下方式将主类添加到您的清单中：

直接添加到Manifest.MF

在pom.xml中为spring-boot-maven-plugin指定Optional Parameters。以下是示例：

<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>

将Spring Boot战争部署到Jenkins
