Question

我正在尝试运行一个项目。它无法找到依赖。所以我在pom.xml中添加了存储库

但它无法查找相同内容。

来自pom.xml

<repositories>
    <repository>

        <releases>
            <enabled>true</enabled>
            <updatePolicy>always</updatePolicy>
            <checksumPolicy>fail</checksumPolicy>
        </releases>
        <snapshots>
            <enabled>true</enabled>
            <updatePolicy>always</updatePolicy>
            <checksumPolicy>fail</checksumPolicy>
        </snapshots>
        <id>spring</id>
        <name>Spring Framework Maven Release Repository</name>
        <url>http://oss.sonatype.org/content/groups/public</url>
        <layout>default</layout>
    </repository>

</repositories>

81749 [警告]无法为其创建Maven项目 com.gemstone.gemfire：gemfire：pom：8.1.0来自存储库。 org.apache.maven.project.ProjectBuildingException：解析错误项目工件：找不到 com.gemstone.gemfire：gemfire：pom：8.1.0 in https://repo.maven.apache.org/maven2被缓存在当地存储库，在更新之前不会重新尝试解析中心间隔已过，或者强制更新项目 com.gemstone.gemfire：的GemFire：POM：8.1.0

当我申请-X时，我看到以下

103850 [DEBUG] === PROJECT BUILD PLAN ================================================
103850 [DEBUG] Project:       xxxxx:xxxxxx:0.0.1-SNAPSHOT

103850 [DEBUG] Repositories (plugins)     : [central (https://repo.maven.apache.org/maven2, default, releases)]

我在这里缺少什么？我有父pom.xml和存储库提及

父母不包括在孩子

鉴于此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>test</groupId>
    <artifactId>test</artifactId>
    <version>0.1-SNAPSHOT</version>
    <dependencies>
        <dependency>
            <groupId>com.gemstone.gemfire</groupId>
            <artifactId>gemfire</artifactId>
            <version>8.1.0</version>
        </dependency>
    </dependencies>
</project>

当我试图跑步时：

$mvn clean compile

结果是：

所以我研究了mvnrepository.com中的依赖关系和存储库，我发现包含这种依赖关系的存储库是Spring Plugins和Spring Libs：

然后我刚刚在我的pom中添加了Spring Plugins存储库，它确实有效！

最终的POM是：

<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">

    <groupId>test</groupId>
    <artifactId>test</artifactId>
    <version>0.1-SNAPSHOT</version>
    <dependencies>
        <dependency>
            <groupId>com.gemstone.gemfire</groupId>
            <artifactId>gemfire</artifactId>
            <version>8.1.0</version>
        </dependency>
    </dependencies>
    <repositories>
        <repository>
            <id>spring</id>
            <url>http://repo.spring.io/plugins-release</url>
        </repository>
    </repositories>
</project>

即使我指定了回购，maven依赖查找也会失败
