无法使用spring-boot项目的1.3.0.RELEASE

Question

I am not able to use 1.3.0.RELEASE version of spring-boot in my project. Following is my pom.xml:

<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.abc</groupId>
    <artifactId>xyz</artifactId>
    <packaging>jar</packaging>

    <parent>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-parent</artifactId>
        <version>1.3.0.RELEASE</version>
    </parent>

    <dependencies>
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-web</artifactId>
        </dependency>
    </dependencies>

    <build>
        <plugins>
            <plugin>
                <groupId>org.springframework.boot</groupId>
                <artifactId>spring-boot-maven-plugin</artifactId>
            </plugin>
        </plugins>
    </build>
</project>

I am getting following error:

Project build error: Non-resolvable parent POM for com.elm:elm:[unknown-version]: Failure to find org.springframework.boot:spring-boot-starter-parent:pom:1.3.0.RELEASE in https://repo.maven.apache.org/maven2 was cached in the local repository, resolution will not be reattempted until the update interval of central has elapsed or updates are forced and 'parent.relativePath' points at wrong local POM pom.xml /elm line 8 Maven pom Loading Problem

Answer 1

Your local cached repository seems to be messed up.

Either you can force maven to download dependencies with

mvn clean install -U

or you can clean your cached repository by removing <USER_HOME>/.m2/repository directory.
