Question

尝试部署具有服务发现模块的弹出启动微服务项目时，我收到以下错误

[ERROR] Failed to execute goal org.springframework.boot:spring-boot-maven-plugin:1.3.5.RELEASE:
run (default-cli) on project serviceDiscovery: An exception occurred while running. null: 
InvocationTargetException: Unable to start embedded container; 
nested exception is org.springframework.boot.context.embedded.EmbeddedServletContainerException:

我发布了我正在使用的pom.xml http://maven.apache.org/xsd/maven-4.0.0.xsd"> 4.0.0

问题始于spring-boot-starter-parent版本1.3.2.RELEASE。它开始出现以下错误

[ERROR]     Non-resolvable import POM: Failure to find 
org.springframework.cloud:spring-cloud-sleuth-dependencies:pom:1.0.2.BUILD-SNAPSHOT 
in https://repo.spring.io/snapshot was cached in the local repository, 
resolution will not be reattempted until the update interval of spring-snapshots 
has elapsed or updates are forced 
@ org.springframework.cloud:spring-cloud-dependencies:Brixton.BUILD-SNAPSHOT, 
/home/soumya/.m2/repository/org/springframework/cloud/spring-cloud-dependencies
/Brixton.BUILD-SNAPSHOT/spring-cloud-dependencies-Brixton.BUILD-SNAPSHOT.pom

我想把spring-boot-parent版本增加到1.3.5，但是它给了我一些在开头提供的问题

Answer 1

Okk，这是解决方案。将父母保持为

<parent>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-parent</artifactId>
    <version>1.3.5.RELEASE</version>
    <relativePath />
    <!-- lookup parent from repository -->
</parent>

现在添加/修改以下依赖关系管理

<dependencyManagement>
    <dependencies>
        <dependency>
            <groupId>org.springframework.cloud</groupId>
            <artifactId>spring-cloud-dependencies</artifactId>
            <version>Brixton.RELEASE</version>
            <type>pom</type>
            <scope>import</scope>
        </dependency>
    </dependencies>
</dependencyManagement>

spring-boot-starter-parent（1.3.5和1.3.2）的两个版本都在工作。实际上我在我的依赖管理中使用 Brixton.BUILD-SNAPSHOT ，现在已经改为 Brixton.RELEASE 。

Answer 2

您可以使用spring-cloud-starter-parent而不是spring-boot-starter-parent。

<parent>
    <groupId>org.springframework.cloud</groupId>
    <artifactId>spring-cloud-starter-parent</artifactId>
    <version>Brixton.RELEASE</version>
    <relativePath/> <!-- lookup parent from repository -->
</parent>
