First here is the configuration:
Apache Maven 3.0.4 (r1232337; 2012-01-17 12:44:56+0400)
Java version: 1.7.0_04, vendor: Oracle Corporation
Default locale: en_US, platform encoding: UTF-8
OS name: "mac os x", version: "10.7.4", arch: "x86_64", family: "mac"
Nexus repository: 2.0.6
The parent POM:
<modelVersion>4.0.0</modelVersion>
<name>Parent POM</name>
<groupId>my.com</groupId>
<artifactId>parent-pom</artifactId>
<version>0.1-SNAPSHOT</version>
<packaging>pom</packaging>
<build>
<pluginManagement>
<plugins>
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-site-plugin</artifactId>
<version>3.1</version>
<configuration>
<reportPlugins>
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-project-info-reports-plugin</artifactId>
<version>2.4</version>
</plugin>
</reportPlugins>
</configuration>
</plugin>
</plugins>
</pluginManagement>
</build>
The aggregation project pom:
<modelVersion>4.0.0</modelVersion>
<name>My Site</name>
<groupId>my.com</groupId>
<artifactId>site</artifactId>
<version>0.1-SNAPSHOT</version>
<packaging>pom</packaging>
<parent>
<groupId>my.com</groupId>
<artifactId>parent-pom</artifactId>
<version>0.1-SNAPSHOT</version>
<relativePath/>
</parent>
<modules>
<module>projA</module>
<module>projB</module>
</modules>
The pom of Project A:
<modelVersion>4.0.0</modelVersion>
<name>Project A</name>
<groupId>my.com</groupId>
<artifactId>projA</artifactId>
<version>0.1-SNAPSHOT</version>
<parent>
<groupId>my.com</groupId>
<artifactId>parent-pom</artifactId>
<version>0.1-SNAPSHOT</version>
<relativePath/>
</parent>
The pom of Project B:
<modelVersion>4.0.0</modelVersion>
<name>Project B</name>
<groupId>my.com</groupId>
<artifactId>projB</artifactId>
<version>0.1-SNAPSHOT</version>
<parent>
<groupId>my.com</groupId>
<artifactId>parent-pom</artifactId>
<version>0.1-SNAPSHOT</version>
<relativePath/>
</parent>
Here is the structure of the folder where I run "mvn clean site":
./pom.xml (aggregation project)
./projA/pom.xml (Project A)
./projB/pom.xml (Project B)
parent-pom is successfully deployed to NEXUS repository before the execution of
mvn clean site with following command:
mvn deploy
-DaltDeploymentRepository=snapshots::default::http://MyServer:8081/nexus/content/repositories/snapshots
And finally the problem itself:
When I run mvn clean site right after the deployment of parent-pom site is
built successfully. If I delete the folder (with its content) "my" (it contains
the parent-pom) from the local repository (~/.m2/repository) and then try to
build the site with mvn clean site I am getting the error described at the
beginning. Actually Maven downloads the parent-pom from the NEXUS. I have
compared the downloaded files and files which have been generated after the
deployment and have realized that few are missing, for instance
maven-metadata-local.xml near to "0.1-SNAPSHOT" folder.
So when I am trying to run the site building job from Jenkins I am getting the
error described above, because the parent-pom is not deployed from the machine
where Jenkins run.
