如何在Maven settings.xml中设置存储库的顺序

Question

我在settings.xml中有3个存储库,因为我需要来自所有存储库的工件.每当找不到依赖项时,Maven就会尝试

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,但大多数时候在中心(repo1)找到工件.我希望Maven先检查这个回购.我在settings.xml中尝试了声明顺序,但是没有用.根据fgysin,我也尝试了相反的顺序,它没有改变任何东西.

我的Maven版本:

C:\>mvn -v
Apache Maven 2.2.1 (r801777; 2009-08-06 21:16:01+0200)
Java version: 1.6.0_15

Answer 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settings.xml中配置repos,我已经读过repos的顺序很有趣,与repos的访问方式相反.

这里有人解释这种好奇心的帖子:http:

Answer 2

在我的情况下,这些答案都不正确..顺序似乎取决于<id>标签的字母顺序,<id>标签是一个任意字符串.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>

另外,请考虑使用Nexus等存储库管理器并在那里配置所有存储库.
