Maven Replacer Plugin StringUtil Issue - maven

Question

I'm trying to implement Maven Replacer Plugin in my build.
However I am stuck with this issue :
[INFO] ------------------------------------------------------------------------
[ERROR] Failed to execute goal com.google.code.maven-replacer-plugin:replacer:1.5.2:replace (default) on project ReportBCSIS: Execution default of goal com.google.code.maven-replacer-plugin:replacer:1.5.2:replace failed: A required class was missing while executing com.google.code.maven-replacer-plugin:replacer:1.5.2:replace: org/apache/commons/lang/StringUtils

[ERROR] -> [Help 1]
Below is my current pom configuration :
<plugin>
<groupId>com.google.code.maven-replacer-plugin</groupId>
<artifactId>replacer</artifactId>
<version>1.5.2</version>
<executions>
<execution>
<phase>prepare-package</phase>
<goals>
<goal>replace</goal>
</goals>
</execution>
</executions>
<configuration>
<file>target/${project.artifactId}/index.jsp</file>
<replacements>
<replacement>
<token>BUILDID-TOKEN</token>
<value>121212-HAHA</value>
</replacement>
</replacements>
</configuration>
</plugin>
Any idea ?

adding text below inside plugin does the trick :
<dependencies>
<dependency>
<groupId>commons-lang</groupId>
<artifactId>commons-lang</artifactId>
<version>2.6</version>
</dependency>
<dependency>
<groupId>commons-io</groupId>
<artifactId>commons-io</artifactId>
<version>2.0.1</version>
<type>jar</type>
<scope>compile</scope>
</dependency>
</dependencies>
