Description

When building CAS-Product with Maven 3, Maven complains about a missing version number for the maven-war-plugin.

[WARNING]
[WARNING] Some problems were encountered while building the effective model for org.apache.oodt:cas-product:war:0.6-SNAPSHOT
[WARNING] 'build.plugins.plugin.version' for org.apache.maven.plugins:maven-war-plugin is missing. @ line 35, column 15
[WARNING]
[WARNING] It is highly recommended to fix these problems because they threaten the stability of your build.
[WARNING]
[WARNING] For this reason, future Maven versions might no longer support building such malformed projects.
[WARNING]

Later during the build it picks up the default version for the plugin:

[INFO] — maven-war-plugin:2.1.1:war (default-war) @ cas-product —

Explicitly stating this version number for the plugin in the POM, as shown below, clears the above warnings:

pom.xml

<plugin>
  <artifactId>maven-war-plugin</artifactId>
  <version>2.1.1</version>
  ...
</plugin>
