爲什麼Maven（錯誤地？）將我的SNAPSHOT部署到版本庫和快照庫？

我在嘗試設置項目以部署到內部聯繫存儲庫時目前遇到問題。由於我對整個Maven都比較陌生，因此我認爲在如何建立分銷管理方面我並沒有真正理解的東西。爲什麼Maven（錯誤地？）將我的SNAPSHOT部署到版本庫和快照庫？

基本問題是，當我執行「mvn deploy」時，工件已成功部署到快照存儲庫，但Maven也試圖將其部署到發佈存儲庫，因爲它應該是失敗的。我對當前配置的理解是，它不應該將其部署到發佈存儲庫。

我已經包含了各種配置元素下方，但如果我其實應該是管理與配置文件中的部分，以便建立快照只定義，併發布版本只定義我想知道。

對此的任何幫助/澄清將不勝感激。

我在我的POM配電管理的以下內容：

<distributionManagement> 
<repository> 
    <id>internal-releases</id> 
    <name>Internal Releases</name> 
    <url>http://localhost:8081/nexus/content/repositories/releases</url> 
</repository> 
<snapshotRepository> 
    <id>internal-snapshots</id> 
    <name>Internal Snapshots</name> 
    <url>http://localhost:8081/nexus/content/repositories/snapshots</url> 
</snapshotRepository> 
</distributionManagement>

其他地方我有以下設置爲允許使用這些存儲庫中獲得文物POM：

<repositories> 
<repository> 
    <id>internal-releases</id> 
    <url>http://localhost:8081/nexus/content/repositories/releases</url> 
    <snapshots><enabled>false</enabled></snapshots> 
</repository> 
<repository> 
    <id>internal-snapshots</id> 
    <url>http://localhost:8081/nexus/content/repositories/snapshots</url> 
    <snapshots><enabled>true</enabled></snapshots> 
</repository> 
<!-- other repos, etc, etc --> 
</repositories>

我在我的settings.xml中有正確的設置來提供證書，以便能夠發佈到我的計算機上運行的此測試nexus實例，並且實際上它正在成功部署快照。

的問題是，它也試圖部署快照釋放存儲庫，它被配置爲禁止快照。

從「MVN部署」輸出包括以下內容：

Nexus的日誌包含以下（因爲我希望它）：

所以最好的線索其實原來是正確的日誌在我的眼前。我曾經想過的唯一的工件是由我正在使用的POM生成的.war，但是您會注意到在日誌中，Maven試圖部署到該版本的工件實際上是一個.jar。

這是不夠的指針（即提供尖上有人Maven用戶郵件列表）來尋找，最終發現有人列入部署階段以下額外的配置。

<plugin> 
<groupId>org.apache.maven.plugins</groupId> 
<artifactId>maven-deploy-plugin</artifactId> 
<executions> 
<execution> 
    <phase>deploy</phase> 
    <goals> 
     <goal>deploy-file</goal> 
    </goals> 
    <configuration> 
     <packaging>jar</packaging> 
     <generatePom>true</generatePom> 
     <url>${project.distributionManagement.repository.url}</url> 
     <artifactId>${project.artifactId}</artifactId> 
     <groupId>${project.groupId}</groupId> 
     <version>${project.version}</version> 
     <file>${project.build.directory}/${project.build.finalName}.jar</file> 
    </configuration> 
    </execution> 
</executions> 
</plugin>

請注意，這實際上是直接引用${project.distributionManagement.repository.url}。另外，這種配置有些誤導，應該通過war插件的attachClasses屬性來完成。

難道是因爲神器版本沒有-SNAPSHOT後綴？

的神器版本是1.0.0，快照，因此沒有。 – imaginaryboy 2010-11-06 02:52:56

定義下列財產在你的POM Maven的部署，插件

<deployFileUrl>${project.distributionManagement.snapshotRepository.url}</deployFileUrl>

更改配置如下：

<plugin> 
    <groupId>org.apache.maven.plugins</groupId> 
    <artifactId>maven-deploy-plugin</artifactId> 
    <version>2.5</version> 
    <configuration> 
     <skip>true</skip> 
    </configuration> 
    <executions> 
     <execution> 
      <phase>deploy</phase> 
      <configuration> 
       <packaging>jar</packaging> 
       <generatePom>true</generatePom> 
       <url>${deployFileUrl}</url> 
       <artifactId>${project.artifactId}</artifactId> 
       <groupId>${project.groupId}</groupId> 
       <version>${project.version}</version> 
       <file>${project.build.directory}/${project.build.finalName}.jar</file> 
      </configuration> 
      <goals> 
       <goal>deploy-file</goal> 
      </goals> 
     </execution> 
    </executions> 
</plugin>

添加以下配置文件設定與存儲庫中的deployFileUrl財產網址

<profiles> 
    <profile> 
     <id>release-mode</id> 
     <properties> 
      <deployFileUrl>${project.distributionManagement.repository.url}</deployFileUrl> 
     </properties> 
    </profile> 
</profiles>

最後調用此配置文件中的maven釋放小插件

<plugin> 
    <groupId>org.apache.maven.plugins</groupId> 
    <artifactId>maven-release-plugin</artifactId> 
    <version>2.0-beta-9</version> 
    <configuration> 
     <releaseProfiles>release-mode</releaseProfiles> 
    </configuration> 
</plugin>
