Maven: Install external JAR automatically

My project has a dependency on oracle jar to connect to it's database. Since it's a external jar, I downloaded it from oracle website and installed it manually using 

mvn install:install-file -Dfile=ojdbc8.jar -DgroupId=com.oracle -DartifactId=ojdbc8 -Dversion=12.2.0.1 -Dpackaging=jar

running maven clean package on local runs fine, since the ojdbc.jar has been installed.

However, now I am moving the build step to Docker image. 

from alpine/git as clone
workdir /app
run git clone --single-branch -b master https://github.com/xxxxxxxx

from maven:3.5-jdk-8-alpine
workdir /app
copy --from=0 /app/idot/idot-backend /app
run mvn clean install -T 1C -DskipTests

from openjdk:8-jre-alpine
workdir /app
copy --from=build /app/target/idot-0.0.1-SNAPSHOT.jar /app
cmd ["java -jar idot-0.0.1-SNAPSHOT.jar"]

This step fails obviously during build since the external jar is not present. So to remove the dependency, I edited the pom.xml to include 

<repositories>
        <repository>
            <id>local-maven-repo</id>
            <url>file://${project.basedir}/libs</url>
        </repository>
</repositories>

and below dependency remains as before

<dependency>
            <groupId>com.oracle</groupId>
            <artifactId>ojdbc8</artifactId>
            <version>12.2.0.1</version>
</dependency>

and then I deploy the jar file using below command 

 mvn deploy:deploy-file -Dfile=ojdbc8.jar -DgroupId=com.oracle -DartifactId=ojdbc8 -Dversion=12.2.0.1 -Durl=file:./libs/ -DrepositoryId=local-maven-repo

This creates a libs folder with ojdbc8-12.2.0.1.jar and other meta information. I check this folder in github

Now while trying to build the docker image it fails with the below error message.

I used same approach, Its works for me. You can see here..

<dependencies>
    <dependency>
        <groupId>org.java-websocket</groupId>
        <artifactId>Java-WebSocket</artifactId>
        <version>1.4.2-SNAPSHOT</version>
    </dependency>
</dependencies>
        
<repositories>
    <repository>
        <id>maven-repository</id>
        <url>file:///${project.basedir}/repo</url>
    </repository>
</repositories>

mvn deploy:deploy-file -Durl="file:\\\<project-path>\repo" -Dfile=Java-WebSocket-1.4.2-SNAPSHOT.jar -DgroupId=org.java-websocket -DartifactId=Java-WebSocket -Dpackaging=jar -Dversion=1.4.2-SNAPSHOT

Instead of all the headaches, I added the same install command in docker file also. It now works fine. 

from alpine/git as clone
workdir /app
run git clone --single-branch -b master https://@github.com/xxxx

from maven:3.5-jdk-8-alpine
workdir /app
copy --from=0 /app/idot/idot-backend /app
run mvn install:install-file -Dfile=/app/ojdbc8.jar -DgroupId=com.oracle -DartifactId=ojdbc8 -Dversion=12.2.0.1 -Dpackaging=jar
run mvn clean install -T 1C -DskipTests

from openjdk:8-jre-alpine
workdir /app
copy --from=build /app/target/idot-0.0.1-SNAPSHOT.jar /app
cmd ["java -jar idot-0.0.1-SNAPSHOT.jar"]
