Roh*_*han 19 java build repository nexus maven-3
我在settings.xml中有以下内容
<mirrors>
<mirror>
<id>paid-jars</id>
<name>jars with license</name>
<url>http://url:8081/nexus/content/repositories/paidjars/</url>
<mirrorOf>!central</mirrorOf>

<mirrorOf>central</mirrorOf>
</mirror>
</mirrors>

在pom.xml中我有两个罐子
但是当我运行maven clean install它时,它试图从Org-central下载licensed.jar.
如何让它使用付费罐子下载?是否有可能首先进入Org-central,如果失败,它会尝试付费罐子?如果是这样,怎么样?我不想把repo条目放在pom.xml中
将Settings.xml

你必须设置镜像
<mirror>
<id>nexus</id>
<mirrorOf>*</mirrorOf>
<url>http://internal/nexus/content/repositories/thirdparty</url>
</mirror>
<mirror>
<id>google</id>
<mirrorOf>google</mirrorOf>
<url>http://google-maven-repository.googlecode.com/svn/repository</url>
</mirror>

然后添加内部和外部回购

如果您需要区分内部(Nexus,Artifactory,..)存储库和 Maven 中心,这里已经讨论过的基于使用<mirrorOf>标签功能的多个镜像的解决方案(如官方文档中所述)工作正常(与此相同)所以问答)。
但是在我们的例子中,我们希望从内部 Nexus 1 下载一些库 - 以及从内部 Nexus 2 下载其他库(具有相同的包名称,但不同的版本),这些解决方案不起作用。我们根本无法使用<mirrorOf>标签。
我们找到了另一种基于多次激活的 Maven 配置文件内部<repository>定义的解决方案(如果没有配置文件定义,它就无法工作!!)。这是我们的:settings.xml
<?xml version="1.0" encoding="UTF-8"?>

如果您正在寻找一个成熟的 . settings.xml,其中 - 除了多个存储库 - 还定义了一个公司代理以及用于推送到公司 Nexus 1的凭据maven-releases和maven-snapshots用户,请查看这个 gist。
如果你想快速检查,如果你的配置正在工作,你可以简单地使用maven-dependency-plugin's dependency:get:
mvn dependency:get \
-DgroupId=your.package.name \
-DartifactId=yourArtifactId \
-Dversion=YOURVERSION \
-Dpackaging=jar

如果这导致 a BUILD SUCCESS,其中至少可以下载一个来自 Nexus 1 的依赖项和一个 Nexus 2 的依赖项,那么一切都应该按预期工作,并且看起来像这样(省略了很多包!):

在settings.xml,mirror使用id和为我工作url的存储库定义profile,如下所示:

指定专用存储库来查找工件是不可能的。Maven 将一一查找所有配置的存储库,直到找到工件。只需将中央镜像和内部存储库添加到settings.xml,就可以了。
阅读Maven 指南以设置多个存储库。关于存储库的顺序,请参阅此答案。
