即使我指定了回購，maven依賴查找失敗

Question

我正在嘗試運行項目。它無法找到依賴關係。所以我在pom.xml中添加了倉庫

但是它無法查找相同。

從pom.xml的

<repositories> 
    <repository> 

     <releases> 
      <enabled>true</enabled> 
      <updatePolicy>always</updatePolicy> 
      <checksumPolicy>fail</checksumPolicy> 
     </releases> 
     <snapshots> 
      <enabled>true</enabled> 
      <updatePolicy>always</updatePolicy> 
      <checksumPolicy>fail</checksumPolicy> 
     </snapshots>

    </repository> 

</repositories> 

81749 [警告]無法創建Maven項目爲 com.gemstone.gemfire：的GemFire：POM：8.1.0從資源庫。 org.apache.maven.project.ProjectBuildingException：錯誤解決 項目神器：未能找到 com.gemstone.gemfire：的GemFire：POM：8.1.0在 https://repo.maven.apache.org/maven2當地 庫被緩存，分辨率不會重新嘗試直到中央的更新 間隔已過或更新被迫項目 com.gemstone.gemfire：的GemFire：POM：8.1.0

當我施加-X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)] 

我在這裏錯過了什麼？我有一個倉庫父pom.xml的提

父母不包括在孩子

鑑於這種pom.xml中：

<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> 

當我試圖運行：

$mvn clean compile 

的結果是：

所以我研究了在mvnrepository.com的依賴和倉庫，我發現，含有這種依賴的資源庫包括Spring插件和Spring利布斯：

然後，我剛添加的春天插件庫在我的POM和有效！

最終的POM是：
