爲什麼Maven會從settings.xml中指定的不同Nexus repo下載依賴項？

Question

我在做什麼不正確的處理JBoss的Nexus存儲庫的這個問題？

我正在嘗試構建JBoss AS7並通過內部Nexus代理服務器代理JBoss公共存儲庫組。我希望通過我的Nexus回購代理整個構建代碼 - 不會碰到jboss.org Nexus回購站。但是，我遇到了一個問題。

一切構建好，直到是時候測試jboss-as-jmx，因爲它想要從附加回購下載工件... /開發人員組。

我在日誌中發現它會嘗試這樣的：

Downloading artifact org.jboss.as:jboss-as-jmx:jar:7.1.2.Final from jboss-developer (http://repository.jboss.org/nexus/content/groups/developer/, releases+snapshots) 

所以我添加的jboss-開發商回購ID到我的Nexus指向http://repository.jboss.org/nexus/content/groups/developer，並把它添加到我的代理JBoss的公共組。然而，這似乎並沒有覆蓋的jboss-開發商回購和Maven仍嘗試從jboss.org

這裏下載神器試驗階段的有問題的日誌輸出：

這裏是我的本地〜/ .m2/settings.xml - 所有其他依賴項工件已由此代理，直到此階段。它仍然不會覆蓋Maven試圖從http://repository.jboss.org下載這個依賴關係，即jboss-as-jmx。

當我運行mvn幫助：有效-POM我看到這個片段

    <repository> 
     <id>jboss-releases-repository</id> 
     <name>JBoss Releases Repository</name> 
     <url>https://repository.jboss.org/nexus/service/local/staging/deploy/maven2/</url> 
    </repository> 
    <snapshotRepository> 
     <id>jboss-snapshots-repository</id>

     <url>https://repository.jboss.org/nexus/content/repositories/snapshots/</url> 
    </snapshotRepository> 
    </distributionManagement> 

這一個：

<jboss.releases.repo.url>https://repository.jboss.org/nexus/service/local/staging/deploy/maven2/</jboss.releases.repo.url> 
<jboss.snapshots.repo.url>https://repository.jboss.org/nexus/content/repositories/snapshots/</jboss.snapshots.repo.url> 

這是奇怪的，因爲我知道所有其他工件都從我的內部nexus代理回購下載OK。接下來我要嘗試的是將這些添加到我的/.m2/settings.xml中

Answer 1

下載這些依賴關係，因爲它們不是maven構建的一部分，而是測試套件的一部分。其中testsuite動態加載以前版本組件的maven依賴關係，以便測試與以前版本的兼容性。

採取如何/在哪裏這樣做是
