maven-metadata.xml is not updated when deploying to nexus

Question

i am using Apache Maven 3.0 Nexus Open Source Edition, Version: 1.8.0.1

this is part of my pom.xml

<plugin>
   <artifactId>maven-deploy-plugin</artifactId>
   <version>2.5</version>
</plugin>
<plugin>
   <artifactId>maven-release-plugin</artifactId>
   <version>2.1</version>
</plugin>

<distributionManagement>
   <repository>
   <id>nexus</id>
   <name>nexus</name>
   <url>http://myrepo/nexus/content/repositories/releases</url>
   </repository>
</distributionManagement>

it is a very simple project. when i do

  mvn release:prepare
  mvn release:perform

everything runs fine:

...
[INFO] [INFO] --- maven-deploy-plugin:2.5:deploy (default-deploy) @ simple ---

Now i download http://myrepo/nexus/content/repositories/.../maven-metadata.xml it looks like this:

<metadata>
<groupId>simple</groupId>
<artifactId>simple</artifactId>
<versioning>
<latest>0.5.8</latest>
<release>0.5.8</release>
<versions>
<version>0.5.9</version>
<version>0.1</version>
<version>0.3</version>
<version>0.4</version>
<version>0.5.1</version>
<version>0.5.2</version>
<version>0.5.3</version>
<version>0.5.4</version>
<version>0.5.5</version>
<version>0.5.6</version>
<version>0.5.7</version>
<version>0.5.8</version>
</versions>
<lastUpdated>20110202190804</lastUpdated>
</versioning>
</metadata>

my latest and just released version is not marked as "latest" and "release".

Now i do "Rebuild Metadata" inside Nexus WebUI. I download metadata after this again. It looks now like this

<metadata>
  <groupId>simple</groupId>
  <artifactId>simple</artifactId>
  <versioning>
    <latest>0.5.9</latest>
    <release>0.5.9</release>
    <versions>
      <version>0.1</version>
      <version>0.3</version>
      <version>0.4</version>
      <version>0.5.1</version>
      <version>0.5.2</version>
      <version>0.5.3</version>

      <version>0.5.4</version>
      <version>0.5.5</version>
      <version>0.5.6</version>
      <version>0.5.7</version>
      <version>0.5.8</version>
      <version>0.5.9</version>

    </versions>
    <lastUpdated>20110202191117</lastUpdated>
  </versioning>
</metadata>

This looks like a bug in nexus or in maven? Does anybody has a solution for this?

Have you tried setting updateReleaseInfo to true in your deploy plugin configuration?

<plugin>
    <artifactId>maven-deploy-plugin</artifactId>
    <version>2.5</version>
    <configuration>
        <updateReleaseInfo>true</updateReleaseInfo>
    </configuration>
</plugin>

Note, I haven't tried this, just happened to have the deploy plugin docs open when I read this question and it seems reasonable.

From the Maven docs:

updateReleaseInfo:
Parameter used to update the metadata to make the artifact as release.

Type: boolean
Required: No
Expression: ${updateReleaseInfo}
Default: false

maven-metadata.xml is not updated when deploying to nexus
