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。
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
<?xml version="1.0" encoding="UTF-8"?> <project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd"> <modelVersion>4.0.0</modelVersion> <groupId>com.test.testapplication</groupId> <artifactId>application</artifactId> <version>1.0-SNAPSHOT</version> <packaging>jar</packaging> <parent> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-parent</artifactId> <version>2.0.0.M1</version> </parent> <repositories> <repository> <id>repository.spring.milestone</id> <name>Spring Milestone Repository</name> <url>http://repo.spring.io/milestone</url> <snapshots> <enabled>false</enabled> </snapshots> </repository> </repositories> <dependencyManagement> <dependencies> <dependency> <groupId>com.test.testplugin</groupId> <artifactId>plugin</artifactId> <version>1.0-SNAPSHOT</version> </dependency> <dependency> <groupId>com.test.testutils</groupId> <artifactId>utils</artifactId> <version>1.0-SNAPSHOT</version> </dependency> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-web</artifactId> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-context</artifactId> </dependency> <dependency> <groupId>junit</groupId> <artifactId>junit</artifactId> </dependency> <dependency> <groupId>org.mockito</groupId> <artifactId>mockito-core</artifactId> </dependency> </dependencies> </dependencyManagement> <build> <plugins> <plugin> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-maven-plugin</artifactId> </plugin> </plugins> </build> <properties> <maven.compiler.source>1.8</maven.compiler.source> <maven.compiler.target>1.8</maven.compiler.target> </properties> </project>
我有一个“ clean Sheat” .m2 settings.xml，并且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。

将Spring Plugin Release Repo添加到中Plugin-Repositories。这样就可以找到了spring-boot-maven- plugin-2.0.0.M1.jar。我已经看到它包含在该回购中
Plugin-Repositories
spring-boot-maven- plugin-2.0.0.M1.jar
将以下各行添加到<project>标记下，如下所示：
<project>
<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，我已经检查了以下内容。请删除<dependencyManagement>和放在<dependencies>下面<project>。最终pom.xml看起来像：
com.test.testplugin
<dependencyManagement>
<dependencies>
