如何配置maven-version以使用Perforce作为SCM提供程序？

Question

我试图使用maven发布插件来创建一个Java项目的发布版本，该项目将Performe作为SCM。

我的pom scm部分是：

<scm>
  <connection>scm:p4:myperforcehostname:1666://mydepot/mycomponent</connection>
  <developerConnection>scm:p4:myperforcehostname:1666://mydepot/mycomponent</developerConnection>
  <url>http://myperforcehostname:1666</url>
</scm>

我还使用P4Maven插件和Maven发布插件：

<plugin>
  <groupId>org.apache.maven.plugins</groupId>
  <artifactId>maven-scm-plugin</artifactId>
  <version>1.4</version>
  <dependencies>
    <dependency>
      <groupId>com.perforce</groupId>
      <artifactId>p4maven</artifactId>
      <version>[2011,2012)</version>
    </dependency>
  </dependencies>
  <configuration>
    <connectionType>connection</connectionType>
    <username>myusernme</username>
    <password>mypassword</password>
    <includes>**</includes>
  </configuration>
</plugin>        
<plugin>
  <groupId>org.apache.maven.plugins</groupId>
  <artifactId>maven-release-plugin</artifactId>
  <version>2.5</version>
</plugin>

当调用“mvn release:prepare-DdryRun=true”时，我得到

[ERROR] Failed to execute goal org.apache.maven.plugins:maven-release-plugin:2.5:prepare 
(default-cli) on project mycomponent: The provider given in the SCM URL could not be found: 
No such provider: 'p4'. -> [Help 1]

有什么想法吗？

我可以调用mvn scm:checkout。

这是我最近做的：

        <plugin>
            <groupId>org.apache.maven.plugins</groupId>
            <artifactId>maven-scm-plugin</artifactId>
            <version>1.9.4</version>
            <dependencies>
                <dependency>
                    <groupId>com.perforce.p4maven</groupId>
                    <artifactId>p4maven-provider</artifactId>
                    <version>1.0.6</version>
                </dependency>
            </dependencies>
        </plugin>
        <plugin>
            <groupId>org.apache.maven.plugins</groupId>
            <artifactId>maven-release-plugin</artifactId>
            <version>2.5.3</version>
            <dependencies>
                <dependency>
                    <groupId>com.perforce.p4maven</groupId>
                    <artifactId>p4maven-provider</artifactId>
                    <version>1.0.6</version>
                </dependency>
            </dependencies>
        </plugin>

然后是一些有用的命令：

mvn scm:changelog -Dusername=yourP4user -Dpassword=yourP4pwd
release:prepare -Dusername=yourP4user -Dpassword=yourP4pwd -autoVersionSubmodules=true -DignoreSnapshots=true

Answer 2

事实证明，P4Maven并不是现成的。我必须从Perforce页面下载它并将其安装到我的存储库中（按照下载zip文件中的说明）。之后，我可以成功地使用p4作为SCM提供程序。

Answer 3

您需要将p4maven作为依赖项添加到maven scm插件以及maven发布插件。

<plugin>
  <groupId>org.apache.maven.plugins</groupId>
  <artifactId>maven-scm-plugin</artifactId>
  <version>1.4</version>
  <dependencies>
    <dependency>
      <groupId>com.perforce</groupId>
      <artifactId>p4maven</artifactId>
      <version>[2011,2012)</version>
    </dependency>
  </dependencies>
  <configuration>
    <connectionType>connection</connectionType>
    <username>username</username>
    <password>password</password>
    <includes>**</includes>
  </configuration>
</plugin>        
<plugin>
  <groupId>org.apache.maven.plugins</groupId>
  <artifactId>maven-release-plugin</artifactId>
  <version>2.5</version>
  <dependencies>
    <!-- P4Maven -->
    <dependency>
      <groupId>com.perforce</groupId>
      <artifactId>p4maven</artifactId>
      <version>[2011,2012)</version>
    </dependency>
  </dependencies>
  <configuration>
    <connectionType>connection</connectionType>
    <username>username</username>
    <password>password</password>
    <includes>**</includes>
  </configuration>
</plugin>
