Hi,

trying to build a WAR-Artifact with:

<build>
<finalName>${artifactId}</finalName>
<sourceDirectory>src/main</sourceDirectory>
<plugins>
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-war-plugin</artifactId>
<version>2.0.1</version>
<configuration>
<warSourceDirectory>web</warSourceDirectory>

<warSourceExcludes>WEB-INF/lib/jta*.jar,WEB-INF/tld/*.tld</warSourceExcludes>
<archive>

<manifestFile>web/META-INF/MANIFEST.MF</manifestFile>
</archive>
</configuration>
</plugin>

...I get the following error:

Embedded error: The attribute "Hudson-Build-Number" may not occur more than once
in the same section
