Add compiled Java Classes to a Maven Project

There are several ways to add compiled external classes to a maven project. This method describes the local repository based method.

  • In the project directory, create a folder called repo, which we'll use as a folder based Maven repository.
  • Create a jar file from the compiled java classes with the following command.
jar cf jar-file input-file(s)


jar cf zql.jar .

  • Deploy the .jar to the file repository, with the following command:
mvn deploy:deploy-file
-Durl=file:///absolute/path/to/your-project/repo \
-DrepositoryId=file.repo \
-Dfile=path-to-your.jar \ \
-DartifactId=the-artifact-name \
-Dversion=1.0 \

mvn deploy:deploy-file -Durl=file:///home/TestProjects/MyImpl/repo -DrepositoryId=file.repo -Dfile=/home/TestProducts/ExternalProject/classes/zql.jar -DgroupId=zql -DartifactId=zql -Dversion=1.0 -Dpackaging=jar;
  • After adding the jar file to repository it looks as follows.

  • Finally add the file repository details and the dependency to your project pom.xml
