Please notice extra slash in your path before train dir
/data//train/models/en/token/en-token.bin
Consider changing reading line to:
InputStream inputStream = new FileInputStream(environment.getProperty("nlp.learning.dir")+ "train/models/en/token/en-token.bin");

I have altered my maven plugin dependency , now it is working fine
<plugin>
<groupId>com.spotify</groupId>
<artifactId>dockerfile-maven-plugin</artifactId>
<version>1.4.7</version>
<!-- Wire up to the default build phases -->
<executions>
<execution>
<id>default</id>
<goals>
<goal>build</goal>
<goal>push</goal>
</goals>
</execution>
</executions>
<configuration>
<repository>${project.artifactId}</repository>
<buildArgs>
<JAR_FILE>target/${project.build.finalName}.jar</JAR_FILE>
</buildArgs>
</configuration>

Most likely you don't have a file src/nlp/train/models/en/token/en-token.bin the same directory as you are building your container from.
parent/
├── Dockerfile
└── src/
└── nlp/
└── train/
└── models/
└── en/
└── token/
└── en-token.bin <--- does this exist?
