I have been trying to rename tika app class. There are loading conflicts due to duplicate classes on the class path. When I try and run maven install -e, it throwing the error and I want to use the

org.apache.tika

class as

com.test1.tika

The pom.xml file is given as below

 <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/xsd/maven-4.0.0.xsd"> <modelVersion>4.0.0</modelVersion> <groupId>com.test1.tika</groupId> <artifactId>tika-app</artifactId> <version>0.0.1-SNAPSHOT</version> <packaging>jar</packaging> <name>tika-app</name> <url>http://maven.apache.org</url> <properties> <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding> </properties> <dependencies> <dependency> <groupId>junit</groupId> <artifactId>junit</artifactId> <version>3.8.1</version> <scope>test</scope> </dependency> <dependency> <groupId>org.apache.tika</groupId> <artifactId>tika-app</artifactId> <version>1.20</version> </dependency> </dependencies> <build> <plugins> <plugin> <groupId>org.apache.maven.plugins</groupId> <artifactId>maven-compiler-plugin</artifactId> <version>2.3</version> <configuration> <source>1.6</source> <target>1.6</target> </configuration> </plugin> <plugin> <groupId>org.apache.maven.plugins</groupId> <artifactId>maven-shade-plugin</artifactId> <version>2.3</version> <configuration> <createSourcesJar>true</createSourcesJar> <relocations> <relocation> <pattern>org.apache.tika.</pattern> <shadedPattern>com.test1.tika.</shadedPattern> </relocation> </relocations> </configuration> <executions> <execution> <phase>package</phase> <goals> <goal>shade</goal> </goals> </execution> </executions> </plugin> </plugins> </build> </project>

The error from the mvn package command is the following:
