Question

我想将我的Spring Boot应用程序上传到生产环境，但是当我构建JAR文件并上传到我的Ubuntu服务器时，我收到此错误：

jar文件中没有主要的清单

这是我的pom.xml

你不应该：

<plugin>
            <!-- Build an executable JAR -->
            <groupId>org.apache.maven.plugins</groupId>
            <artifactId>maven-jar-plugin</artifactId>
            <version>2.6</version>
            <configuration>
                <archive>
                    <manifest>
                        <mainClass>com.blockisland.BootApp</mainClass>
                    </manifest>
                </archive>
            </configuration>
        </plugin>

spring-boot-maven-plugin负责构建捆绑了所有依赖项的应用程序。

Spring Boot jar没有主要的清单错误
