问题始于 spring-boot-starter-parent 版本 1.3.2.RELEASE.它开始出现以下错误
The problem started with with spring-boot-starter-parent version 1.3.2.RELEASE. It started giving the following error
[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
我想将 spring-boot-parent 版本增加到 1.3.5 但它给我带来了另一组问题,正如开头提供的
I thought of increasing the spring-boot-parent version to 1.3.5 but it gave me another set of problems as provided at the beginning
推荐答案
好的,这里是解决方案.保持父级为
Okk, here is the solution.Keep the parent as
<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/修改如下依赖管理
Now add / modify the following dependency management
<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,我在依赖项管理中使用了 Brixton.BUILD-SNAPSHOT,现在已更改为 Brixton.RELEASE.
Both versions of spring-boot-starter-parent (1.3.5 and 1.3.2) are working.Actually I was using Brixton.BUILD-SNAPSHOT in my dependency-management which has now been changed to Brixton.RELEASE.
