-----------------------------------------

hadoop-project patch failure is expect.

The way to show this issue is the following pom file
{noformat}
<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
         xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/maven-v4_0_0.xsd">
    <modelVersion>4.0.0</modelVersion>

    <groupId>org.apache.test</groupId>
    <artifactId>test</artifactId>
    <packaging>jar</packaging>
    <version>1.0.0</version>
    <name>test</name>
    <description>test</description>

    <dependencies>
        <dependency>
        <groupId>org.apache.hadoop</groupId>
        <artifactId>hadoop-common</artifactId>
        <version>0.23.1</version>
        <scope>compile</scope>
        </dependency>
    </dependencies>

    <build>
    </build>
</project>

{noformat}
MAVEN_HOME=<path to apache-maven-2.2.1> PATH=<path to apache-maven-2.2.1/bin>:$PATH mvn clean install -e -X > ~/build.log 2>&1
build.log will show the above error.

Error is not present with the above patch.
