如何在 Maven 设置中设置存储库的顺序.xml

我的设置中有3个存储库.xml因为我需要所有这些存储库中的工件。每当找不到依赖项时，Maven 都会尝试

Downloading: http://some.server/mvn2repo/releases/org/apache/lucene/lucene-core/2.9.1/...
[INFO] Unable to find resource 'org.apache.lucene:lucene-core:pom:2.9.1' in repository
Downloading: http://some.server/mvn2repo/3rdParty/org/apache/lucene/lucene-core/2.9.1/...
[INFO] Unable to find resource 'org.apache.lucene:lucene-core:pom:2.9.1' in repository
Downloading: http://repo1.maven.org/maven2/org/apache/lucene/lucene-core/2.9.1/lucene-core-2.9.1.pom
<success>

所有存储库，但大多数时候当然会在中心（repo1）中找到工件。我希望Maven首先检查此存储库。我尝试了设置中的声明顺序.xml，但不起作用。根据fgysin的说法，我也尝试了相反的顺序，这并没有改变任何东西。

我的专家版本：

答案 1

据我所知，pom.xml中存储库的顺序也将决定存储库访问的顺序。

至于在设置中配置存储库.xml，我已经读到存储库的顺序很有趣，与访问存储库的顺序相反。

这里有一篇文章，有人解释了这种好奇心：

答案 2

在我的情况下，这些答案都不正确。顺序似乎取决于<id>标记的字母顺序，这是一个任意字符串。因此，这个强制回购搜索顺序：

            <repository>
                <id>1_maven.apache.org</id>
                <releases>  <enabled>true</enabled>  </releases>
                <snapshots> <enabled>true</enabled> </snapshots>
                <url>https://repo.maven.apache.org/maven2</url>
                <layout>default</layout>
            </repository>

            <repository>
                <id>2_maven.oracle.com</id>
                <releases>  <enabled>true</enabled>  </releases>
                <snapshots> <enabled>false</enabled> </snapshots>
                <url>https://maven.oracle.com</url>
                <layout>default</layout>
            </repository>
