我的pom文件如下:

<project xmlns="maven.apache/POM/4.0.0" xmlns:xsi="www.w3/2001/XMLSchema-instance" xsi:schemaLocation="maven.apache/POM/4.0.0 maven.apache/maven-v4_0_0.xsd"> <modelVersion>4.0.0</modelVersion> <parent> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-parent</artifactId> <version>1.4.1.RELEASE</version> </parent> <groupId>sample.api</groupId> <artifactId>api.test</artifactId> <version>0.0.1-SNAPSHOT</version> <name>api.testMaven Webapp</name> <url>maven.apache</url> <dependencies> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-web</artifactId> </dependency> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-actuator</artifactId> </dependency> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-test</artifactId> <scope>test</scope> </dependency> </dependencies> <properties> <java.version>1.8</java.version> </properties> <build> <finalName>api.test</finalName> <plugins> <plugin> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-maven-plugin</artifactId> </plugin> </plugins> </build> </project>

我不知道如何解决此问题.我尝试清洁和重建，甚至重新导入.我看过类似的问题，例如此 但似乎没有任何作用.

And I am at a loss for how to fix this issue. I tried cleaning and rebuilding, even re-importing. I looked at similar questions like this but nothing seems to work.

让程序运行的唯一方法是将父pom更改为版本1.3.1.RELEASE，但是我不想使用此版本，也不想使用1.4.1.RELEASE

The only way I got the program to run was by changing the parent pom to version 1.3.1.RELEASE But I do not want to use this version and want to use 1.4.1.RELEASE

任何帮助将不胜感激.

推荐答案

以下动作对我有用

运行mvn dependency:purge-local-repository删除所有依赖项并强制重新下载.

然后执行mvn clean verify

Run mvn dependency:purge-local-repository to remove all dependencies and force a re-download.

Then do a mvn clean verify
