How to include local jar files in Maven project [duplicate]

by

Although it works to use the systemPath reference, it is better to create a local repository. And fortunately, it is easy to do.

Creating a local repository holding jars not available in a public repository

NOTE: I use Eclipse, so some of the instructions are specific to Eclipse. Most are easily generalizable.

Assumptions

  • The jar was created by Maven in another project with the following…

    <groupId>com.foo</groupId>
<artifactId>test</artifactId>
<version>0.1.1</version>
<packaging>jar</packaging>

In Project (that wants to access the jars)

  • Create repo directory just off the project base directory
  • For each jar to be accessed locally…
    • add directories for each level of the groupID (ex. /repo/com/foo)
    • add jar name (aka artifactId) without the version (ex. /repo/com/foo/test)
    • add directory for the version of the jar (ex. /repo/com/foo/test/0.1.1)
    • put the jar in that directory (ex. /repo/com/foo/test/0.1.1/test-0.1.1.jar)

In pom.xml (for the project that wants to access the jars)

  • Define the local repository

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

  • Add the dependency on the local jar. From our example above, this would be…

    <dependency>
  <groupId>com.foo</groupId>
  <artifactId>test</artifactId>
  <version>0.1.1</version>
</dependency>

Rebuild

  • Rt click pom.xml -> Run as -> Maven build
