Maven 2.x Install Plugin

Do you have an example project that we can use to verify this issue?
It would also be good is you could supply more information about your environment, like Java version, Maven version etc.

I've just started seeing this same problem. I am running Maven builds from the Bamboo build server on a faster machine than I was on and am running multiple builds simultaneously.

We have the same Problem, using Continuum doing 'mvn deploy' simultaneously to the developers.

Same problem with simultaneous installs of a common parent library or pom on hudson.

Java 1.5.0_15
Maven 2.1.0
Maven Install Plugin 2.2

I received this error as well, not on my machine, just on the machine where runs Hudson.
I manage to make it back to work removing the maven-metadata-local.xml in the folder
/home/boxo-proto/.m2/repository/net/phaedra/phaedra-commons/0.6.2/

Both my machine and CI server run with ubuntu 9.10, sun JDK 6.

here was the output:

We're experiencing the same problem. We run

• Archiva 1.2.1
• CentOS release 5 (Final)
• Java 1.6.0_02
• Maven 2.2.1

[INFO] Retrieving previous metadata from snapshots 
[INFO] ------------------------------------------------------------------------
[ERROR] BUILD ERROR
[INFO] ------------------------------------------------------------------------

[INFO] ------------------------------------------------------------------------

This problem occurs on a regular basis (daily) and causes problems with our builds since artifacts cannot be deployed and builds fail. The corrupt metadata needs to be repaired manually which is quite a lot of work. Quite nerve wrecking when you really need that build and Archiva goes booooom.

An example for corrupt metadata look like this:

<metadata>
  <groupId>com.some.group</groupId>
  <artifactId>html</artifactId>
  <versioning>
    <latest>0.1-SNAPSHOT</latest>
    <versions>
      <version>0.1-SNAPSHOT</version>
    </versions>
    <lastUpdated>20100202145220</lastUpdated>
  </versioning>
</metadata>
>html</artifactId>
  <versioning>
    <latest>0.1-SNAPSHOT</latest>
    <versions>
      <version>0.1-SNAPSHOT</version>
    </versions>
    <lastUpdated>20100202163215</lastUpdated>
  </versioning>
</metadata>

I forgot to mention: Our environment is not multi threaded for artifact updates.

Also affects maven-install-plugin version 2.3

A similar problem did occur right now at our site

Using maven 22.1, Hudson 1.397 on a 8-core Linux-VM during release of one project.

Previously we had fixed down the use of mave-parent:0.12 (with install-plugin:2.2/invoker:1.2) via a dependcy-declaration.

We removed the maven-parent-version-lock (which was there for some unknown reasons) and the error suddenly occured (now install:2.3 and invoker:1.5) are used.

Is the patch of Geoff planned to be integrated?
