Question

我决定将spring-boot-starter-parent更新到版本2.0.0.M1，以便将它与Spring Core 5.0.0.RC1一起使用。

但是，我在从Spring里程碑存储库下载依赖项时遇到问题。

我的pom.xml

我有一个＆＃34;干净的衣服＆＃34; .m2 settings.xml，我已经清理了我的本地存储库，并确保我可以连接到spring milestone存储库。

Answer 1

将Spring Plugin Release Repo添加到Plugin-Repositories。这样它就可以找到spring-boot-maven-plugin-2.0.0.M1.jar。我看到它包含在that repo

中

在<project>标记下添加以下行：

<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，我已检查过以下内容。请移除<dependencyManagement>并将<dependencies>置于<project>下。最终pom.xml看起来像：

Answer 2

要使用spring-boot里程碑版本，请在<project></project>：

之间添加以下 pom.xml

<repositories>
    <!-- for spring milestone -->
    <repository>
        <id>spring.milestone</id>
        <url>http://repo.spring.io/milestone</url>
    </repository>
</repositories>
<pluginRepositories>
    <!-- for spring milestone -->
    <pluginRepository>
        <id>spring.milestone</id>
        <url>http://repo.spring.io/milestone</url>
    </pluginRepository>
</pluginRepositories>

Answer 3

For 

  `<parent>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-parent</artifactId>
        <version>2.0.0.M7</version>
    </parent>`

将下面的存储库标记放在pom.xml中，它帮助我构建了项目。

<repositories>
    <repository>
        <id>spring-milestones</id>
        <name>Spring Milestones</name>
        <url>https://repo.spring.io/milestone</url>
        <snapshots>
            <enabled>false</enabled>
        </snapshots>
    </repository>
    <repository>
        <id>repository.springframework.maven.release</id>
        <name>Spring Framework Maven Release Repository</name>
        <url>http://maven.springframework.org/milestone/</url>
    </repository>
    <repository>
        <id>org.springframework</id>
        <url> http://maven.springframework.org/snapshot</url>
    </repository>
    <repository>
        <id>spring-milestone</id>
        <name>Spring Maven MILESTONE Repository</name>
        <url>http://repo.spring.io/libs-milestone</url>
    </repository>
    <repository>
        <id>spring-release</id>
        <name>Spring Maven RELEASE Repository</name>
        <url>http://repo.spring.io/libs-release</url>
    </repository>
</repositories>
<pluginRepositories>
    <pluginRepository>
        <id>spring-milestones</id>
        <name>Spring Milestones</name>
        <url>https://repo.spring.io/milestone</url>
        <snapshots>
            <enabled>false</enabled>
        </snapshots>
    </pluginRepository>
</pluginRepositories>

Answer 4

将以下内容添加到pom.xml文件中。

 <repositories>
    <repository>
        <id>spring-snapshots</id>
        <name>Spring Snapshots</name>
        <url>https://repo.spring.io/snapshot</url>
        <snapshots>
            <enabled>true</enabled>
        </snapshots>
    </repository>
    <repository>
        <id>spring-milestones</id>
        <name>Spring Milestones</name>
        <url>https://repo.spring.io/milestone</url>
        <snapshots>
            <enabled>false</enabled>
        </snapshots>
    </repository>
</repositories>

<pluginRepositories>
    <pluginRepository>
        <id>spring-snapshots</id>
        <name>Spring Snapshots</name>
        <url>https://repo.spring.io/snapshot</url>
        <snapshots>
            <enabled>true</enabled>
        </snapshots>
    </pluginRepository>
    <pluginRepository>
        <id>spring-milestones</id>
        <name>Spring Milestones</name>
        <url>https://repo.spring.io/milestone</url>
        <snapshots>
            <enabled>false</enabled>
        </snapshots>
    </pluginRepository>
</pluginRepositories>

我建议您将Spring Boot版本更新到最新版本以获取最新的依赖项，目前它是2.0.0.M6，其中包含Spring 5.0.1.RELEASE的依赖项管理。

<parent>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-parent</artifactId>
    <version>2.0.0.M6</version>
    <relativePath/> <!-- lookup parent from repository -->
</parent>

或者从Spring Initializer生成一个基于Spring Boot 2.0的新项目，所有依赖项都将得到解决。

Answer 5

我没有“干净的表” settings.xml，因为我有一个个人镜像URL。解决此问题的唯一方法是在我的settings.xml中包含@Hantsy答案，而不是pom.xml

Answer 6

如果您在中国，则可以通过修改settings.xml文件来解决此问题：

<mirror>
    <id>nexus-aliyun</id>
    <mirrorOf>*</mirrorOf>
    <name>Nexus aliyun</name>
    <url>http://maven.aliyun.com/nexus/content/groups/public</url>
</mirror>

我的

settings.xml路径：C：\ Program Files \ apache-maven-3.6.0 \ conf \ settings.xml

Answer 7

这个问题有点老了，但是我在这里更新，希望它可以对某人有所帮助。

就我而言，脱机工作已得到检查，因此我遇到了错误。

这是我已解决的问题。在Mac中，导航至IntelliJ菜单，然后选择首选项或快捷键（Command +，）。

搜索专家并选择。然后uncheck 脱机工作（如果已选中）。

Answer 8

要解决此问题，请尝试单击重新导入所有Maven项目按钮：：
