安装 wikidata-query-rdf / Blazegraph 失败

Question

我正在尝试安装 wikidata-query-rdf (https://github.com/wikimedia/wikidata-query-rdf)，但 Blazegraph 出现故障：

git clone https://gerrit.wikimedia.org/r/wikidata/query/rdf wikidata-query-rdf
cd wikidata-query-rdf
sudo mvn install

我第一次收到这种警告： [警告] com.blazegraph:bigdata-cache:jar:2.1.5-SNAPSHOT 的 POM 丢失，没有可用的依赖信息

然后：

Answer 1

Maven 找不到某些依赖项。您可以看到它正在查找一个只有版本但没有快照可用的存储库。

您应该将 SNAPSHOT 存储库添加到父 pom.xml 文件：

<repositories>
       ....
  <repository>
            <id>wmf.snapshots</id>
            <url>https://archiva.wikimedia.org/repository/snapshots</url>
  </repository>
</repositories>

或者，将 Blazegraph 依赖版本属性更改为最新发布版本：

<properties>
        <blazegraph.version>2.1.4</blazegraph.version>
        ...
</properties>
