原因：不是v4.0.0 POM

使用maven運行時出現生成錯誤。下面是錯誤代碼片段。原因：不是v4.0.0 POM

我已經添加了maven repo，然後adobe repo。 Internally build嘗試通過Maven回購找到Vault插件，這會導致錯誤FNF，然後嘗試Adobe回購。 Vault插件存在於adobe repo上，但它僅下載了帶有301消息的POM。

任何想法。

POM片段：

<repositories> 
     <repository> 
      <id>maven-central</id> 
      <name>Maven2</name> 
      <url>http://repo1.maven.org/maven2/</url> 
     </repository> 
     <repository> 
      <id>adobe-public</id> 
      <name>Adobe</name> 
      <url>https://repo.adobe.com/nexus/content/groups/public/</url> 
     </repository> 
    </repositories>

更改爲HTTPS後，回落不會發生在土坯。下面是錯誤：

看起來你正在做一個公司代理或防火牆...在哪裏不允許通過... – khmarbaise

@khmarbaise：沒有下載的jar在http://repo1.maven.org/maven2/com /day/jcr/vault/maven-vault-plugin/0.0.10/maven-vault-plugin-0.0.10.jar。我懷疑whay fallback沒有轉移到adobe repo。 – zdhim

你請求一個URL http並返回一個301重定向到URL https。由於安全風險，這些方案之間的重定向不會被默認遵守。當請求POM時，僅檢索到具有81ffbd1712afe8cdf138b570c0fc9934742c33c1作爲SHA1校驗和的301重定向HTML頁面。然後檢索POM URL + .sha1，該POM應在第一行中具有POM的校驗和並將它們進行比較。在這裏你再次獲得301重定向頁面，所以81ffbd1712afe8cdf138b570c0fc9934742c33c1與'<html>\n<head><title>301'進行比較，這當然不匹配。

直接配置https URL代替Adobe回購，它應該工作得很好。
