Я пытался настроить проект deeplearning4j и OpenCV на Linux через maven, но я получаю UnsatisfiedLinkError:

Мои зависимости выглядят так:
<dependency>
<groupId>org.openpnp</groupId>
<artifactId>opencv</artifactId>
<version>3.4.2-1</version>
</dependency>
<dependency>
<groupId>org.nd4j</groupId>
<artifactId>nd4j-native-platform</artifactId>
<version>1.0.0-beta6</version>
<classifier>linux-x86_64</classifier>
</dependency>
<dependency>
<groupId>org.deeplearning4j</groupId>
<artifactId>deeplearning4j-core</artifactId>
<version>1.0.0-beta6</version>
</dependency>
<dependency>
<groupId>org.deeplearning4j</groupId>
<artifactId>deeplearning4j-modelimport</artifactId>
<version>1.0.0-beta6</version>
</dependency>
И Я нахожу решение на этой странице: deeplearning4j
Затем я делаю из него следующую команду: cd /root/.javacpp/cache/openblas-0.3.7-1.5.2-linux-x86_64.jar/org/bytedeco/openblas/linux-x86_64; cp libopenblas.so.0 libopenblas_nolapack.so.0
Это работает, похоже на ошибку пакета jar. Но я Хотите найти стандартное решение, такое как изменение зависимостей или использовать maven build для его решения, а не файловую операцию, как я могу это сделать?
Я нахожу в зависимости openblas pom, у него есть плагин сборки
<plugin>
<artifactId>maven-jar-plugin</artifactId>
<executions>
<execution>
<id>javacpp-${javacpp.platform}</id>
<phase>package</phase>
<configuration>
<excludes>

</excludes>
</configuration>
</execution>
</executions>
</plugin>
Я вижу, что libopenblas_nolapack был исключен в <exclude>org/bytedeco/openblas/${javacpp.platform}/*libopenblas_nolapack*</exclude>, так это проблема?
