找不到Spring Boot Starter Parent 2.0.0依赖项 [英] Spring boot starter parent 2.0.0 not found dependency

问题描述

我决定将spring-boot-starter-parent升级到2.0.0.M1版本，以便与Spring Core 5.0.0.RC1一起使用.

I decided to update my spring-boot-starter-parent to version 2.0.0.M1 in order to use it with Spring Core 5.0.0.RC1.

但是，我在从Spring里程碑存储库下载依赖项时遇到问题.

But, i am having issues downloading the dependency from the Spring milestone repository.

我的pom.xml

我有一个"clean Sheat" .m2 settings.xml，并且我已经清理了本地存储库，并确保可以连接到spring里程碑存储库.

I have a "clean sheat" .m2 settings.xml, and i have cleaned my local repository, and made sure i can connect to the spring milestone repository.

推荐答案

添加 Spring插件发行版到Plugin-Repositories.这样它就可以找到spring-boot-maven-plugin-2.0.0.M1.jar.我已经看到它包含在

Add Spring Plugin Release Repo to Plugin-Repositories. So that it can find the spring-boot-maven-plugin-2.0.0.M1.jar. I have seen that it contains in that repo

在<project>标记下添加以下几行，如下所示:

Add the below lines under <project> tag as like:

<project>
<!------ others lines -->
    <pluginRepositories>
        <pluginRepository>
            <id>repository.spring.release</id>
            <name>Spring GA Repository</name>
            <url>https://repo.spring.io/plugins-release/</url>
        </pluginRepository>
    </pluginRepositories>
</project>

编辑

由于我没有com.test.testplugin，因此我检查了以下内容.请删除<dependencyManagement>并将<dependencies>放在<project>下.最终的pom.xml如下:

As I have no com.test.testplugin, I have checked with the followings. Please, remove the <dependencyManagement> and put <dependencies> under <project>. Final pom.xml looks like:
