外部Jars用于部署在heroku中的spring boot应用程序

Question

This question may seems duplicate but I tried all the options but no luck.

I want to add a external jar which is not there in maven repository in to my spring boot bulk jar. This application is deployed in the heroku cloud and is ran using the command

java -Dserver.port=$PORT  -jar target/myjar.jar

I tried various scenarios to fix this

1.

<dependency>
         <groupId>exjar</groupId>
         <artifactId>exjar</artifactId>
         <scope>system</scope>
         <version>JDK7</version>
         <systemPath>${project.basedir}/lib/exjar-JDK7.jar</systemPath>
      </dependency> 

2.

java -Dserver.port=$PORT -Dloader.path="lib/*" -jar target/myjar.jar

3. maven-install-plugin

None of the above worked. I want to try below approach, any idea of how to execute this command in heroku?

mvn install:install-file
   -Dfile=<path-to-file>
   -DgroupId=<group-id>
   -DartifactId=<artifact-id>
   -Dversion=<version>
   -Dpackaging=<packaging>
   -DgeneratePom=true

Any solution is appreciated.

Answer 1

Add following repository in you pom

<repositories>  
   <repository>
     <id>external</id>
     <name>External Project Repo</name>
     <url>file:///${project.basedir}/lib</url>
   </repository>
</repositories>

then add the dependency

  <dependency>
     <groupId>exjar</groupId>
     <artifactId>exjar</artifactId>
     <version>jdk7</version>
  </dependency> 

When you finished building your myjar.jar should have BOOT-INF/lib/exjar-jdk7.jar
