我正在尝试从多模块 Maven 项目构建一个独立的 .jar。

项目结构为

ema-server/ shared/ # 与 Java 客户端共享 rest-api/ # Spring REST API server/ # 为独立提供 main() 并捆绑在一起 web/ # 一个简单的 AngularJS Web 服务器

该server/模块的存在是为了构建独立 .jar的. 为此，它取决于rest-api/包含@SpringBootApplication.

你可以看看我拼命尝试完成这项工作，但这是我目前的“解决方案”：

模块的pom.xml：server/

<plugin>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-maven-plugin</artifactId>
    <configuration>
        <fork>true</fork>
        <mainClass>org.ema.server.Server</mainClass>
    </configuration>
    <executions>
        <execution>
            <goals>
                <goal>repackage</goal>
            </goals>
        </execution>
    </executions>
</plugin>
<plugin>
    <artifactId>maven-assembly-plugin</artifactId>
    <version>2.2-beta-5</version>
    <configuration>
        <archive>
            <manifest>
                <addClasspath>true</addClasspath>
                <mainClass>org.ema.server.Server</mainClass>
            </manifest>
        </archive>
        <descriptorRefs>
            <descriptorRef>jar-with-dependencies</descriptorRef>
        </descriptorRefs>
    </configuration>
    <executions>
        <execution>
            <id>assemble-all</id>
            <phase>package</phase>
            <goals>
                <goal>single</goal>
            </goals>
        </execution>
    </executions>
</plugin>

我想在这里声明，如果我在 Eclipse 中将这个东西作为 Java 应用程序运行，那么一切正常。

但是，如果我运行“独立” java "*" org.ema.server.Server，我会得到：

org.springframework.beans.factory.BeanDefinitionStoreException: Failed to process import candidates for configuration class [org.ema.server.Server]; nested exception is java.lang.IllegalArgumentException: No auto configuration classes found in META-INF/spring.factories.

您可以在此处查看完整的输出。

有人可以告诉我如何使这项工作吗？

如果我能提供更多信息，请告诉我。
