从外部文件读取属性-Maven

Question

我必须读取多个maven项目共享的属性，为此，我尝试使用属性maven插件，如：

<plugin>
            <groupId>org.codehaus.mojo</groupId>
            <artifactId>properties-maven-plugin</artifactId>
            <version>1.0-alpha-1</version>
                <configuration>
                <files>
                    <file>conf.properties</file>
                </files>
            </configuration>
            <executions>
                <execution>
                    <phase>initialize</phase>
                    <goals>
                        <goal>read-project-properties</goal>
                    </goals>
                </execution>
            </executions>
        </plugin>
        </plugins>
        </build>
<distributionManagement>
    <snapshotRepository>
        <id>snapshots</id>
        <url>${nexusurl}</url>
    </snapshotRepository>
</distributionManagement>
</project>    

文件conf.properties包含：

 nexusurl=http://localhost:8081/nexus/content/repositories/snapshots

问题是，当使用mvn-deploy时，属性nexurel没有得到解决，导致的错误跟踪是：

[ERROR] Failed to execute goal org.apache.maven.plugins:maven-deploy-plugin:2.7:deploy
(default- deploy) on project parent: Failed to deploy artifacts/metadata: No connector 
available to access repository snapshots (${nexusurl}) of type default using the 
available  factories WagonRepositoryConnectorFactory -> [Help 1]
org.apache.maven.lifecycle.LifecycleExecutionException: Failed to execute
goal   org.apache.maven.plugins:maven-deploy-plugin:2.7:deploy (default-deploy) on 
project  parent: Failed to deploy artifacts/metadata: No connector available to 
access repository snapshots (${nexusurl}) of type default using the available
factories WagonRepositoryConnectorFactory

我曾试图更改插件的执行阶段（验证、安装、部署），将插件的版本更改为1.0-alpha-2，但问题仍然存在。

我将感谢任何援助。谢谢，

问题是pom.xml的读取和属性集成要早于插件加载。您可以将插件用于构建中的值，例如插件之间的值，但您试图做的事情不会像那样工作。
