Maven：发布插件在<distributionManagement>中看不到我的<repository>

Question

To make Maven "deploy" to a directory, I use this:

<distributionManagement>
    <downloadUrl>http://code.google.com/p/junitdiff/downloads/list</downloadUrl>
    <repository>
        <id>local-hack-repo</id>
        <name>LocalDir</name>
        <url>file://${project.basedir}/dist-maven</url>
    </repository>
    <snapshotRepository>
        <id>jboss-snapshots-repository</id>
        <name>JBoss Snapshots Repository</name>
        <!--
        <url>https://repository.jboss.org/nexus/content/repositories/snapshots</url>
        -->
        <url>file://${project.basedir}/dist-maven</url>
    </snapshotRepository>
</distributionManagement>

This appears in the effective pom.

...
<distributionManagement>
<repository>
  <id>local-hack-repo</id>
  <name>LocalDir</name>
  <url>file:///home/ondra/work/TOOLS/JUnitDiff/github/dist-maven</url>
</repository>
<snapshotRepository>
  <id>jboss-snapshots-repository</id>
  <name>JBoss Snapshots Repository</name>
  <url>file:///home/ondra/work/TOOLS/JUnitDiff/github/dist-maven</url>
</snapshotRepository>
<downloadUrl>http://code.google.com/p/junitdiff/downloads/list</downloadUrl>
</distributionManagement>

But still, Maven insists that it's not there:

[INFO] [ERROR] Failed to execute goal org.apache.maven.plugins:maven-deploy-plugin:2.7:deploy (default-deploy) on project JUnitDiff: Deployment failed: repository element was not specified in the POM inside distributionManagement element or in -DaltDeploymentRepository=id::layout::url parameter -> [Help 1]

...

I am using it through the maven-release-plugin.

Update: This ^^^ seems to be the key part - mvn deploy works fine.

What's wrong?

Maven 3.0.4. Pom to be added.

由于maven-release-plugin不仅可以使用本地文件，还可以使用版本控制中的文件，因此它实际使用的文件看起来像缺少<distributionManagement>标记。
